[@Dedonus] Question: 

Why would Christopher want to recruit War-Pulse, but not the guy with the giant mech? I mean, maybe the whole thing with the helicopter, and those news people, but c'mon, GIANT BADASS MECH that went toe-to-toe with a guy who could probably fight Icon one-on-one.

Because War-Pulse has faced the main villains of the story arc.  They also worked together briefly in D-Day.
