No one follows Transformers?
The way I see it:
Devastator+
Menasor
vs
Superion
I think Superion could take them both. Usually, he has the edge against Menasor, and he could probably one shot Devastator. And in Takara's Headmasters, he did well against them both.
Bruticusvs
Defensor
Defensor can take him.
Predakingvs
Raiden
Raiden is the gestalt formed from the train bots, introduced in Takara's Headmasters. They've fought a number of times, and imo Predakings had the edge.. Raiden's no lightweight, but he's not quite in Predakings class.
Predaking wins.
Abominusvs
Computron
Both have beaten the other, but I think it would go as it did in Return of Optimus Prime:
"You talk too much, BLAM!"
Abominus beats Uber Nerd.
So that leaves us with
Superion and Defensorvs
Predaking and Abominus
Predaking alone can probably win this. The only way this isn't over in moments is if Defensor erects a shield, and he can't maintain one forever.

I had the G1 cartoon in mind, but you can do one for applicable comic book continuity, if you want.
Pretty sure Raiden only exists in the Headmasters cartoon though.. And the Autobots are kind of short on gestalts.
I suppose you can just sub in Omega Supreme or Sky Lynx.
