This is Transform-Oh
, with the Bulkhead-styled mecha
as a replacement arm. Not sure there's not much else that needs to be said. I could note, however, that although he has a new arm, he still has the same fist (Transform-Oh's fists come out of the chest of the Optimus-based mecha).
Somehow, working on stuff like this, I keep thinking of the various finishers from Power Rangers Samurai. I don't even like that show much, but the theme music is AWESOME.
Ugh, those cheesy things the monsters say when they die...
