That's wolverine. And it's deadpool with his fingers behind his head. Wolverine hates deadpool but deadpool loves messing with wolverine. Wolverine is who dp got his regenerative powers from so neither one can die. Also dp started in the x men series and then got his own series. Holy shit I never thought I would explain the relationship between two fictional characters like this.
And some one has a two fingers behind whoever that is on the right beside Spider-Man
