Even though Deadpool and the Punisher typically fight for the same side in the Marvel Universe the two gun happy dispensers of vigilante justice have clashed over the years, most recently in the mini-series Deadpool Vs. The Punisher.

So instead of having one of your nerdy dreams come true please enjoy this fan made trailer for Marvel's The Punisher Vs. Deadpool by Stryder HD. (NSFW language)
