Wow, this art is so inconsistant. Just look at how huge Bombstrike is compared to Lifeline who's in front of her. (and please, no puns should be made from my comment)

As for who the blond guy is... I'm gonna go on a limb and say it's Lt. Stone from the GIJoe Extreme series. And why not? Sgt. Savage and Freight are there, as are all of the guys from Savage's toyline.
