Nope he is not Spike was only made for thatr Crap of a Show. GAMBIT WAS EVIL. Spike is not and will never be a part of the X-Men world. Any thing that has to do with X-Men Evo is not X-Men. How dare Silent bring that up.
Yes Silent the show was fake, a sham, false. It was like a really bad X-Men Dream that lasted for 3 years. If I had to pick I'd take X3 over that anyday.
