If Deadpool is ever killed, he will best be remembered for his never-ending mouth, for he says a lot during encounters with others. A part of the Weapon X project, Deadpool is a ruthless, cold-blooded assassin who is very skilled in combat.
The last true issue where Deadpool and Shatterstar clashed was in X-Force #11, where Deadpool was seeking out the fake Domino at the X-Force headquarters. Shatterstar was glad he finally had a true equal for a challenge, but Deadpool quickly disabled Shatterstar with a blow in the midsection, knocking the wind out of Shatterstar. It remains to be seen, though, when they will once again encounter and Shatterstar can pay back his debt to Deadpool.
