You know after all this time, I Finally read your post, Zereil.
Dont take it to the Literal sense about the Batman-Spiderman derivitive. It ws'nt that depp. I was'nt going as so far to say that THEY are alike. Spiderman has made his own legacy. I was merely noting that, Batman has a 30 year jump on Spidey, and it's NO Coincidence in Comic history, that most heroes at that time were either on foot, OR Flying like Superman. Once Bat's came in 1939, He does'nt Fly, yet he's swinging from building to building. And the fact that both of theirs names contains an animal/and "man" at the end, is no accident. Batman was the blue print. Marvel (thankfully) was able to create a newer character, Based off of a more interesting animal than a bat, and thus making him a very enjoyable comic book heroe. And as for swingin, Spidey owns it, and perfected. Spidey gives swinging style.
And Batman uses the moblie for Certain situation, basically for getting around the city, or car chases. But open any book, and he's hardly using it. Infact he probably just takes it out just so he can get back home. He mostly makes rounds on rooftops and looks down for crime. If he see's the joker down at street level blocks away causing chaos, he's not going to go run to the batmobile, he's going to swing down there.
HOWEVER, since you brought it up, they do have some thing similar. Both were created by crime related deaths to family members. One one has a vendetta, one is holding a promise.
