Ok here's the fifth member of my teen-created team FORCE! His name is Impulse, and I think he was also a leader contender with G-Force. I saw the two having arguments much like Cyclops and Wolverine. Impulse had super instincts that would warn him of dangers right before they would happen. In fact, they were so strong that many times he would react to something before he consciously would register it!
(And before you can say it, yes I'm aware of the DC Impulse character. This guy was created in my mind YEARS before that! :D )
