my teenage time controlling edgelord

(does he even count as an OC if I did like, half of the initial developing and then picked him up as my own later?)
okay, so, his name is Seth and he was originally a GMPC that was meant to become the main villain of SBARG, but the previous person that had rping duties for him was kind of a dick so me and the rest of the staff for SBARGv2 decided to change his fate so he didn't have to be tossed aside (and as a huge middle finger to the last guy).
A lot of stuff for his character was formulated so that he'd drift into assuming the bad guy role, so we started him out as this pathetic whiny 13 year old that shops at hot topic and swears too much, and then gave him time powers and a hit list to follow (me and the team decided he would only go after dreamselves with the other rper's permission and that worked out fairly well) to be more threatening.

I wound up being the next in line to rp and write for him since I knew more about him than the previous actor did. After the original session ended, I struggled for a while with playing as him, because I had never really considered myself edgy in any manner, but he grew on me. But, what helped the most with developing him, was writing a narrative-based Let's play of Link's Awakening with him as the main character. Eventually, one rpg maker game later, I finally had him developed in a rounded manner (and I began swearing out of character too @ _@).
At this point, he's a kinda rude but protective 18 year old who has duties regarding keeping the wheel of time turning in his universe (the session was successful... against all odds). He's also kinda confused regarding if he's a human or not, considering that he has some odd features compared to everyone else from his  session (completely pale #ffffff white skintone, a weirdly angular jawline, two horns on his head that resemble bec's ears that can detect the passage of time, and weird pointy notches in front of his earholes instead of regular looking ears.) He's also a scythe user because relevant symbolism to older plot points (and the artist who first drew him with a scythe made it look pretty badass). A lot of other characters give him flack for maining such an inefficient weapon, but he sticks with what he knows because it looks cool. He's currently dating an alternate version of a girl that he had once accidentally killed before the universe was remixed/rebooted/whatever. He's also in close contact with a ton of ghosts of his doomed timeclones, most of which are jealous that he gets to be the alpha Seth.
I could probably talk all day about him, but I'm gonna stop now.
