Those characters can die and deal with really dark themes. Your character does neither.

It just sounds like you can't handle some equilibrium. Dark stuff needs comedy to contrast the dark and enhance it, otherwise you just get super boring things. Imagine Batman TAS for example, or Adventure time, or Steven Universe. They have their dark and their comedic. Sure the latter two are more lighthearted, but if we do batman TAS for example, they still had comedy all the time. Mostly joker stuff, but it was still comedy. Heck, did you see all the innuendos that Harley was involved in?

Have you been in lots of RPS where someone did a comedic character and didn't keep it in the confines or tone of the RP? It can be done and done well, but you'll never see if it you don't give people a chance :P.
