You can see this guy's remains in Endless Frontier.

Well one thing why everything's easier is because of the twin system.

nah Dygen breaker is my invented move that can wipe out big mechs. Dygenguard combines with SRX and SRX simply throws everything it has along with Dygenguard running at them and later stabs the sword in the enemy and turns into the colossal zankantou that is what i call a special move

hmm? I wonder how the Wurger lifted that thing, lol

If we were going with that, it's have to start with RHB, then TBS, followed by Rampage Ghost and finished with R-Formation. Actually, no... Reverse R-Formation and Rampage Ghost, since this is Kyosuke and Excellen's villain. In fact, screw Royal Heartbreaker and throw Tornado Blade in there instead.

then rampage ghost followed by a royal heartbreaker XD

Now THAT is how you end a final battle. Although I think it would have been better to start with Twin Bird Strike and end with R-Formation. TBS would carry over after the SRX team get pushed off the screen, and then you'd get R-Formation's dynamic kill.

lots of mecha series like to use german words for weapons names and stuff.

What's up with Banpresto's obsession with German?

Yep that's "GO!!" playing it plays when you reduce Sterns Hp enough.

Is the SRW Impact main theme playing in the background?

He still looks pretty cool.
