The Energon Pub

Can someone tell me which 2 characters these are and from what show they are from?
Thanks in advance!

The hero is Ippatsuman from the series Gyakuten! Ippatsuman: https://en.wikipedia.org/wiki/Gyakuten!_Ippatsuman



(Hmm, that certainly ends....interestingly.)

His mecha is called the Gyakuten-Oh.

Luckily this guy was featured in the video game "Tatsunoko Vs. Capcom" for the Wii, so it was super simple to dig up a little info for you(and I think I remember looking it up once too).

Wow! Thanks so much for your detailed help.
I will have to look no further...
