My Lord and Saviour Dust Man is the only option here
(Comeback of the century lets go)

Dust Man

It is futile in voting for anyone else but the rules require it...

Air Man
Mega Man
LarkMan.EXE

Pluto - (I have nothing to add but need to extend this comment)

The machines are the final bosses of each main series game, whatever contraption Wily is fighting you with

No 1
No 4
No 6
No 9

Pluto
Rush

Pluto
Tundra Man
Quint
Rush

Flash Man

Tornado Man

But Omega Parallel Protoeon is unable to do that because the final super gear only exists in the original universe, held by Magnum Pyre who is in hiding (because him and celestial jewel were immune to the tomline events so there is only one final super gear despite the other 6 existing in multiple tomlines), so you'll have to find and fight him to get it

Y'all need to play MM11
Its pretty good and all the RMs show some personality. Fuse Man at least said a bad pun, What does Star Man show?

Acid Man
Tornado Man

Soil tycoon goes down round one, nice

Centaur Man
Flash Man

Magnum Pyre apparently put himself and celestial jewel in a time homeostasis prior to all these tomline shenanigans resulting in them not having 2 alternate versions of themselves (even though Alternate Pyre never existed in the first place)

The nuclear blast from the T-Pose caused the final super gear to unfuse from Celestial Jewel.
Magnum Pyre picks it up and surges with power (but still not aware of any thing that has happened with the other gears) and goes into hiding to plan his REVANGE against evry juan eggnoring him

Pyre is completely lost at what is happening but suddenly...
Pyre merges with Parallel Pyre (Alternate Pyre isn't real) and forms Magnum Pyre!
Magnum Pyre decides to attack celstial jewel with a nuclear T-Pose for no apparent reason

Hmm...
So the way this is set up is that my picks are going against my own picks...
In that case I can't wait for a full round of 8 Wily Machines (make it happen eon)

Centaur Man
Slash Man
Turbo Man
Splash Woman

Fuse Man
Acid Man
Tornado Man
Gemini Man

RM with an ugly, annoying vertical stage with AI so bad that it's only beaten by Toad Man in that department or some cool dude who just wants to kill X

Vile all the way

Pyre finds Ninja Ghost annoying and blames Beta Shadow for bringing him here. In retaliation, Pyre uses SUPER MEGA HYPER EXTREME ULTRASPACE RUDE BUSTER (totally not ripped from Deltarune) on Beta Shadow. Beta Shadow is hit so hard that he is flown back at the asteroid Aeon hit and impacts it with such a force that it sends a massive shockwave throughout the universe and creates a new Big Bang.

The slap is so powerful that it creates a rift in the space-time continuum causing a newcomer named Pyre to fall out of a portal directly in front of alternate spectre

This is going to be meme-y and bad but I'll do it anyway

There is only one character to vote and that is my Lord and Saviour Dust Man

It is futile for anyone other than Dust Man to win but just in case the impossible happens...
