I was just about to guess him. Um......no I wasn't. That's a fucking shit addition to be fair. All that history and they go for (after a Google search) some guy from Rome: Total War 2?
Edit: They've also added someone called General Winter from Company of Heroes 2 apparently, although I think these are PC additions only. Sort your colleagues out Dave, this would instantly sell millions if they added Segata Sanshiro to the roster.
They've said they're going to add one more character from the community vote so i'm guessing this was something Sega bugged them to do. It won't necessarily be the top voted either.
Tbh i'd be happy with any of the top voted apart from Miku.
It seems ridiculous to drop the rest of it. Sonic and friends were in Transformed, anyone who wants Sonic in a car is catered for, so why not add Tyris Flare on a dragon for the rest of us?
