Cool!!!

 Thanks, I will include a reference then

I've filled in the gaps for "The Dark Dimension Cyberman."  Also, I've made him a boss here, but it can work as a very strong mob.

Name: Cyber-Commander (Boss)

Attack Style: It will run or sprint at the player, since it's more agile than other Cybermen, it can also walk, but only when it is very close to the player.

Spawning: On any planet/dimension. Rarely.

Nature: Hostile

Special Traits:  Can shout "All life shall be converted!" or "All will be Cybermen!" when active. Additionally, when inactive, there will be Cybermen guarding it.

Drops: Steel (obviously) but in great quantities [greater than the normal drops].

Can also drop its Head as a reminder of how terrifying and dangerous the Cybermen can actually be.

Stats: Has a greater amount of health than any other boss (if mob, it will have 50 health points).

Attacks/Abilities: Will use its claws or fists to attack the player  (Note: The claws will do more damage than its fists). 

Can spawn other cybermen (Classic, Tenth Planet, Cybus, etc.) [If mob, it will summon nearby Cyber-Mobs for assistance].

If it kills the player, it will convert the player's "corpse" into a Cyberman (a Cyberman will spawn with the player's name attached).

Once it defeats the player, there is an extremely rare chance that it will enact (what I call) "The Endgame Protocol," which makes all nearby Cybermen/Cyber-Mobs attack each other, since, by logic, they think that there aren't any other beings to convert, so termination is made primary procedure.

Notable Weaknesses: If player can avoid the Cyber-Commander for a period of 30 seconds or longer, it will stop and "recharge," rendering it inactive for five seconds or longer (not to breach seven seconds) allowing the player to attack it mercilessly (other methods are not excluded[such as just attacking it outright]).

Can also jump as high as a player.

Can also break blocks weaker than Obsidian (if met with an Obsidian or Bedrock block, it will attempt to break it, and will eventually get there[Note: It will break the weaker blocks at the speed of a Diamond {or Brass, depending on how good it is |I don't know|} Pickaxe). This prevents the player from Nerdpoling away from danger or blocking the Cyber-Commander's path.

Is invulnerable to Lava and cannot be damaged/drowned in Water.

Any weapons mentioned by ArcPheonix will damage it more than conventional weapons (i.e. diamond swords, bows).

Suggestion for implementation: The structures mentioned by ArcPheonix can spawn a Cyber-Commander if left unchecked or it can spawn as mentioned.

Why it should be implemented: It would add more danger and risk of death/defeat to the current version of the Dalek Mod, seeing as all that is needed to kill Cybermen is a structure (Nerdpole)  that allows the player to attack them from above or a wall that blocks the Cyberman from getting to the player.

Any other information: It should be taller than the average Cyberman (maybe four blocks?) and it should look like image ArcPheonix has posted or close enough to the point of recognizing it as a Cyber-Commander.

Feel free to say this should be removed or put somewhere else, otherwise, do what you like with it.

 I really like this. I'll start adding this into the main post

Added. Also, I fixed the Table of contents. It was pretty off and outdated

Why, thank you. :)

There's a fan series being made about The Dark Dimension at the moment. I got most of the information from one of the videos it appeared in and put it into this format. Whenever an opportunity emerges to fill in the blanks I'll use it.

I think there's two suggestions that could be added:

The Cyber Time-Squad and the Cyber..."Things" in "The Fate of Krelos" (I'll find out what they're called when I re-listen to it);

And I think I can work the Cyber-Hunters into that Time-Squad. I'll work on both of them later, but thank you for not removing my earlier post.

There'll be an edit later when I find out what they're called.

EDIT: Well...the best they call them are "Headsets" but I'll call them "Cyber-Headsets."

Drat. I've found errors.

In "Notable Weaknesses", the "Can also break blocks weaker than Obsidian" shouldn't be there as well as "Is invulnerable to lava and cannot be damaged/drowned in Water." The second detail (concerning Lava and Water) should be in "Attacks/Abilities." The "Can also break blocks weaker than Obsidian" should be removed from "Notable Weaknesses."

This isn't your fault, since I suspect you copied and pasted from mine, which has those errors.

Now, to work on the mentioned: "Cyber Time-Squad" and "Cyber-Headsets."

 Thank you for catching that. Just updated it.

Never heard of either, but I'm looking forward to hearing the details

Now, to work...again since the last time I typed this it didn't save it...apparently.

Name: Cyber-Headset

As heard in: The Fate of Krelos

Reference Image: 

Ignore the thing in the top-left corner, that's just K-9 photobombing.

Details: There are two forms of the Cyber-Headset: 1) The "Unconverted" Form in the reference image or 2) The "Converted" Form, when it has Cyber-Converted a Villager of its own accord or has been spawned by a Cyberman upon Cyber-Conversion of a Villager. 

Description: The "Unconverted" Form will look like the reference image while the "Converted" Form will have its tentacle around the Villager's head and its (the Cyber-Headset's) head will be resting on the Villager's head. Upon conversion of the Villager, more tentacles will spawn and move in an upwardly direction and, when undisturbed, move like a Squid. When attacking, all the tentacles will be pointing to the entity it's attacking (except for the one that's holding onto the Villager).

Spawning: Wherever a Cyberman can spawn, an "Unconverted" Cyber-Headset can spawn; it will have the same spawn rate as a Cyberman.  Otherwise, the "Converted" Cyber-Headset will spawn when a Cyberman converts a Villager or when an "Unconverted" Cyber-Headset converts a Villager.

Nature: Hostile

Attack Style: Melee

Special Traits: It exists as a separate entity to the Villager. It will control the Villager's body upon Cyber-Conversion.

Drops: Once again, steel, but, rarely, it can also drop itself (the Cyber-Headset); the same thing will happen if it's killed before the Villager itself. It will be broken, but, if repaired in an anvil with four blocks of steel, can be turned into a Anti-Cyber-Headset, which can cure all Converted Villagers in a 10x10 area once before breaking completely.

Stats: It will have the same amount of health as a Cyber-Villager when on a Villager's head when in its "Converted" Form; in its "Unconverted" Form it will have the speed and health of a Silverfish. When on top of a Villager's head as a "Converted" Cyber-Headset, it will control the Villager's body to have the speed of a running Villager.

Attacks/Abilities: Will use its tentacle(s) to attack the player or Villager for Cyber-Conversion in "Converted" Form; in its "Unconverted" Form, it will attack like a Silverfish.

Upon killing the player, a Mob will spawn with the player's skin with the Cyber-Headset, since the player's corpse has been Cyber-Converted.

Notable Weaknesses: Interference with the Sonic Screwdriver (right-clicking on the Cyber-Headset) will frenzy it for 10 seconds, making it attack any other Cyber-Mob, but it can also mercilessly attack the player. Additionally, after the first attempt, the time needed to interfere with the Sonic Screwdriver will increase, then, after the second time, it will increase again, then it will increase again, etc., etc.

Suggestion for Implementation: The structures that ArcPheonix has mentioned can spawn an "Unconverted" Cyber-Headset or when a Cyberman has converted a Villager, the "Converted" Form of the Cyber-Headset will spawn on top of its head, controlling it until its death.

Why it should be Implemented: It would add more variety to the effects of Cyber-Conversion, since there's only one result of  a Villager's Cyber-Conversion and that is a Cyber-Villager...which is basically just a Cybus Cyberman's head on top of a Villager's body.

Any other information: The Cyber-Headset should not replace the Cyber-Villager result from Cyber-Conversion. There should be a 50/50 chance of the Villager either being a Cyber-Villager or having a "Converted" Cyber-Headset when a Cyberman converts the Villager. When an "Unconverted" Cyber-Headset converts a Villager, there is only the chance of a "Converted" Cyber-Headset controlling the Villager as the end result (the "Unconverted" Cyber-Headset will despawn, because it is now a "Converted" Cyber-Headset).

While I was listening to "The Fate of Krelos" and "Return to Telos," I came up with two more suggestions: The Particulate Vacuum Cleaner; and Cyber-Particles.

These two are the easiest, so I'll format them first.

Name: Particulate Vacuum Cleaner

Description: The Doctor has this somewhere in his TARDIS. Thankfully, it was on hand to foil the Cybermen's Temporal Agenda via their Cyber-Particles, so, by association, it can go into this thread. Also, it's the only item that I know that can eliminate Cyber-Particles. "We should put it on E-Bay. See what it gets."

As heard in: The Fate of Krelos; Return to Telos

Suggestion for Implementation: When a Cyber-Mob has been killed, there's a rare chance that a "Data Log (Signed Book)" will drop, having entries in it that a Cyberman would do in its daily routine ("Systems ...Online...."; "Conversion of 32 Compatibles"; etc.) but it would go from most recent to most earliest, so that the first statement in the "Data Log" would be "TERMINATION" followed by "Dispersion of Infectious Cyber-Particles halted by Device known as: 'Particulate Vacuum Cleaner.'"Giving reason for the player to have one, so that they can avoid conversion by Cyber-Particles.

How does the player obtain it: The player obtains it either by crafting it or by finding it in a chest.

(Note: The Particulate Vacuum itself is made of two parts: The Motor and The Bag which holds the Cyber-Particles).

Why Should this be Implemented: It allows more ways to defeat the Cybermen than just killing them with swords and bows.

How it Should Look: It should just look like a portable Vacuum Cleaner...sounds strange but that's basically it.

Any Other Information: Unlike most weapons, the durability on the Particulate Vacuum Cleaner works in reverse. When the bar is completely filled, it must be "cleaned" by putting the Vacuum Cleaner in a Crafting Table for it can be dismantled into the Motor and Bag. The Bag can be cleaned by crafting it with Gold Nuggets in a Crafting Table. Then you put the Bag and Motor back into the Crafting Table to complete the Vacuum Cleaner. Additionally, It eliminates Cyber-Particles by Right-Clicking.

Name: Cyber-Particles

Description: These particles can infect anything that's remotely technological. and they're nearly impossible to see. The only way to be sure they are eliminated is by cleaning the area with a Particulate Vacuum Cleaner. Otherwise, the mentioned effect shall occur and Cybermen will come to integrate it into their systems by taking it while converting any nearby compatibles in the process.

As heard in: Return to Telos

Attack Style: Wither/Poison Effects (Compatible Mobs). Conversion Abilities (Turning an item or block into a piece of Cyber-Technology).

Spawning: In the Cyber-Structures ArcPheonix has mentioned; Rare; from Cybermen.

Nature: Hostile.

Stats: The stats of a Silverfish.

Attacks/Abilities: Able to convert anything remotely technological into Cyber-Technology (Bows become Cyber-Guns; Solar Cells become Batteries; Arrows become Vastial Cartridges [The Cybermen's form of Ammunition {I suggest just using gray rectangles with green specks at the top for their texture}]).

When the Compatibles have all been converted, they will take all the Cyber-Technology that is nearby into their inventories for integration into the Cyber-Systems.

They are able to convert any Compatibles into their Cyber-Counterparts.

If the player is killed by them, a Mob will spawn with the player's skin, but grayed out, and will continue to become grayer and grayer, and will start exhibiting Cyber-Parts until it is a complete Cyberman.

Invulnerable to every weapon except the Particulate Vacuum Cleaner.

Once all the nearby Compatibles are Converted, all Cyber-Mobs will move as one group to the nearest group of Cybermen, then, when they reach that group, they will then move as a group to the next nearest group of Cybermen and so on and so on. While this occurs, the Cyber-Particles will work to make (spawn) more Cyber-Particles to infect and convert other clusters of Compatibles, then, when that's been done, they will follow the same process that has been described.

This includes TARDIS' for Cyber-Conversion by Cyber-Particles.Once a TARDIS has been converted, the Cybermen would then create the Cyber Time-Squad...or was it already here?

These Cyber-Particles can work on Daleks, Autons, Clockwork Droids, K-9, sadly (before the hatred starts, it happened in the story the Cyber-Particles came from so don't blame me), and even the Empty Child and the Empty People, since they're being converted by a technological advancement (the Nanogenes).

Any Mob that has been suggested by ArcPheonix can be converted by Cyber-Particles into their Cyber-Counterparts.

Even other Mobs that the Cybermen have no use for (yet...) can be converted, they'll just look like they're a part of the Cyber-Race (in other words, they'll look like they're made out of steel), but are in fact "Neutral" until attacked.

Notable Weaknesses: The Particulate Vacuum Cleaner.

If a TARDIS has been infected by Cyber-Particles then the only way to cure it would be to travel in that TARDIS  to and from dimensions/planets/eras. Only then will your TARDIS be free of the Cybermen. Unfortunately for you, the longer your TARDIS is under the control of the Cybermen, the more trips are needed to cure it and also unfortunately, the technology they learnt is still in their databanks...

There will be a Timer in place to measure how much time has passed since your TARDIS has been underneath the control of the Cybermen. If it was 0-20 minutes, it will need five trips to be cured. If it was 21-40 minutes, it will need 10 trips. If it was 41-60 minutes, it will need 15 trips and if it was 61-80 minutes, it would need 20 trips to be cured. This rate of change will go up to 1 Week, after that, your TARDIS is irretrievable from the Cybermen.

(Note: The Exterior will become more Cyber-like as time passes and once the TARDIS is cured it will become normal again).

[Additional Note: The Interior will not show signs of conversion {i.e. gray blocks; steel blocks} so that the owner can use the "/tardis-interior-pos X Y Z" command to save their Interior, but the Exterior cannot be saved. Unfortunately, the Cybermen can enter that TARDIS from the old Exterior and try to convert the interior until the owner stops them. The mentioned process for curing the TARDIS will work {The Interior will still not show signs of conversion, instead, the monitor display will look more Cyber-Like as time passes until the TARDIS is cured and there will be Cybermen in that TARDIS}].

Suggestion for Implementation: The Cyber-Structures mentioned by ArcPheonix can spawn them, as well as Cybermen who detect Compatibles but cannot convert them because they only have the capacity to convert Humanoids so they spawn the Cyber-Particles to convert them.

Why It Should be Implemented: It adds more variability to the Cyber-Conversion process and gives a bigger threat of the Cybermen taking over everything in Minecraftia.

Any Other Information: They should be very, very, very....(an eternity later)...very hard to spot and if you do spot them, they will spot you...
They can only be defeated by the Particulate Vacuum Cleaner, so whenever you encounter a Cyberman that's walking away from a nearby Compatible...be very, very careful...

They should be a single pixel in length, width, height, and depth and they move in groups.

 I'll add these in too, though I feel a bit iffy about some of the details around having the particles take over Tardises.

Which details exactly?

 Well, never mind.

About the timer, do you think it would be a part of the HUD, and item, or a block?

I think it would be a part of the TARDIS Interface on the Monitor (that is what you mean by HUD?). To be honest, in the story (The Fate of Krelos; Return to Telos) it started to convert the TARDIS immediately and it was just luck that the Doctor was there when it started.

I can be sarcastic and mean sometimes but even I'm not that evil.

As for which Doctor it was that stopped the conversion, it was the one before the one that appeared in Spare Parts.

 For the HUD, I mean like the Breath Meter, EXP Bar,  Armor bar, hunger bar, and inventory. How they're all part of the player's HUD.

And ok.

Also, does the conversion count for ingame time only or does time offline also count (in the case of a multiplayer server)? 

Well, now that that's cleared up. Yes, it will be a part of the HUD.

And yes, time offline counts (that's why I put 1 Week as the irretrievable point).

Now, to work on the Cyber Time-Squad...again.
