i watched this a long time ago in a land far far away.
it's like this: there's this dude, and he like dies or something, then he sorta regains his strength and is given an exosuit armor typo thing. his suite is all white, sorta spiky, and he has a double ended spear sword thingy. his shoulder opens up and rockets come out. his mission is to protect earth from these weird giant spider things. ok, my description is really really corny, but bear with me. he goes to earth, and fights the spider things. he alse meets his evil brother, who has a red version of a similar kind of suite. and they battle all throughout the show. on earth, scientist made their own suite, and it's got this huge plasma cannon thingy on the guy's shoulder. they picked a guy to pilot it, and he helps the good guy (the guy with the rocket shoulders and white suite). at the end, i remember that he defeats his evil brother, and a small spider thing comes out of his body, showing that he was possessed the whole time by the spider. after the spider leaves his body, he becomes good, and dies in like a minute. this is japanese anime btw.
sory bout the horrible descirption, but u have to help me. i really want to c this show again. it's not eska flowne or gundam wing. gundam is like a mobile suite, where people sit in a cockpit of this giant thing 2-3 stories tall. in this show, the suite is like an armor worn by the guy. so he's about he same size as he was before. does that ring any bells? go ahead and laugh if u think this is stupid, but if u know anything bout this, please help me.
