Answer 1

...sounds very much like the 1991 sci-fi/action flick, "The Guyver", which was based on the Japanese anime; actor Mark Hamill starred in the film, and his character was the one who became the mutated spider creature, at the end of the film...

...check it out, here; there WAS a 1994 sequel, in fact, entitled "Guyver: Dark Hero", as well...
