Since this is a character who is not in games, and hasn’t appeared since his last episode, I don’t have much to compare with his future or origin since… well this is it. In fact other than fanfiction, Captain N is still sat in the palace of Power, well other than the rather striking image which was the last ever preview with Captain N in it.
Anyway, so other than that Kevin never reappears. Of course that is because his whole purpose is to familiarize people with Videoland. As such he’s really meant to represent the viewer, similar to how Dr Who has an assistant who’s usually not travelled with him around the universe before, so the viewer gets a similar experience to the Doctor’s Assistant. However Kevin has an extra part to his character, as he’s played and beaten almost every game out there, and as such he has a lot of knowledge of what to do, but he’s still just one of us, and at the end of the day, even if he knows for example how to beat King Hippo in Punchout!!, actually having the strength to beat him, even with knowledge of his weak points, is a whole other matter.
This is a key point with Kevin that his character is pretty weak, and must use his knowledge to win. That said he also has quick reactions due to his time playing games, so with the Zapper he’s pretty deadly.
One other important point about his character is that he’s pretty much a loser outside Videoland. In the real world, he doesn’t seem to actually have any friends (at least none are ever shown) and the few others from his home we meet either don’t know him, or hate his guts. Mike Vincent is the main one of Kevin's friends shown, and whilst they've grown apart to the extent that Mike now bully's Kevin (is it me or is there a Gary Oak thing going on here?), it's shown in the end that Mike was a decent guy underneath. I think given the chance Mike would of been real and died at the end of the episode, it's only due to the censorship etc that he was an android. This is really an important development in proving that Kevin's bettered himself, and he knows that he can reason with his enemies instead of out rightly killing them.
Also of note, is that one of the biggest character developments is sadly in the unintentional final episode. We get to see here that due to Kevin’s jealousy and need to have Lana like him, he actually is corrupted by evil influence. Of course it’s a typical ‘hero gets hypnotised’ episode, but I do feel it is clever in the way that Kevin is only hypnotised due to there being dark thoughts at the back of his mind which he could be influenced into acting upon.
And that’s about it for this history in animation. This character only appeared in animation, and therefore I can’t do the game to animation comparison.
