I haven't established his character much at all. I was playing him like an extension of his 616 version, basically. 

As for events, Deadpool assisted Wolverine and others in capturing the hulk for the Professor. They brought Banner back to base, where Valkyrie broke the Hulk loose and they ravaged the facility. Team X was broken up after the Professor revealed that he had been controlling the minds of his agents. The facility was blown up by a nuke and Wolverine was captured; the other agents are presumed to have escaped.
