Fracture already fought Captain Stupendous in the early issues, he knocked major power-clone's original pretty much out of the fight with One punch. So yeah, if MP and Fracture go at it all out, with fracture not even bothering with holding back (he was, in that fight, mostly just trying to protect a shop getting robbed and defending himself) then MP is so in for a lesson in humility.
Black Rose--Brooder knows nothing of this. Brooder is concerned about Janjawid hiring assassins and terrorists to go after Fusion, as well as political fallout here at home.
