Because he literally transformed from Spider-Man
Ok this one needs a little explanation. In the first version of Revenge of Shinobi, you actually have a boss fight against Spider-Man AND Batman. When you beat Spider-Man he actually transforms into Batman. Sound crazy? Check it out for yourself.
This was obviously changed in the second version of the game but that's crazy, eh?
Yes. And to prove that it's legit, you can play the original version, and it gives copyright claims to both Marvel and DC.
baman and piderman!
Does what a neighbor hood Spider-man can because he's Batman.
In the second version its a mutant batman if i recall, SHINOBI IS AWESOME
Nana nana nana nana nana nana SPIDERBAT!
Spidey and Batman in the same game together!? AWESOME
I didn't know Peter Parker was Batman!!
This just proves that Batman and Spiderman are the most famous of all super heroes. It makes me so glad that Spiderman is finally going to be in a Death Battle. I want Spiderman's opponent to be Batman. Make it happen Screwattack.
WTF! i knew i shoul have bought this game
and he can fly too.
wow, best boss fight of all time
