@Weird Tales Overall I like the character, but there's two things that bother me, the surfboard and the trident. The trident especially bothers me as the Sample Post indicates that Jason's abilities are a blessing from the Hawaiian gods, but the Trident is a Greek weapon. My suggestion to you would be to look up Hawaiian/Polynesian/Samoan weapons and choosing something that would be more thematically appropriate. The surfboard on the other hand just seems redundant with Jason's strength and swimming speed. As there's no mention of his stamina, I suppose it could be argued that he needs the board to reserve it, but over the course of the RP he'd have very few chances to truly use the surfboard. Remember this RP is set around the adventures of the group at a school, it's not a Teen Titans RP where they're going to be sent off on missions.
Aside from those two gripes, you'll need to double check the rules as you're missing a small something from your notes before I can accept the character.
