He says it's Axle's son and three original characters. That bulking dude looks like a mix between Hagar and Blanka. Blangar.
So we got carbon copy of Axel, anime waifu, evil Haggar, and Will Smith... they all look fucking boring. What's the point of coming up with a son for Axel if he's going to look exactly like him? You might as well just use Axel himself, even if he's old as damn... actually, an old looking Axel sounds far more interesting for a protagonist than a son that looks exactly like he did. The compensation for Blaze fucking sucks, I don't even need to say why. The hip hop dude is so generic that it makes Lucky Glauber from KOF look like an actually well thought design-- they could've at least made his clothes be a little more unique, because his outfit alone looks too bland. At least the wrestling looking guy looks kind of cool. I just don't get why his hair is orange, it just kind of seems to clash with the rest of his color scheme.
The fact that Axel's son is called "Burn": Sounds like a very flamey name, dunnit? Can we surmise Axel and Blaze got busy? Is the dude on the right Sammy/Skate all growed up or another member of the Hunter clan?
