I added some weaknesses to Haze (my oc).
He can be touched, but only gods and demigods can kill him, he only trims off the dying parts of the universe if they could actually harm the multiverse (otherwise he has no power and can't do anything to anyone and could be killed by anyone if they manage to use an effective weapon), he isn't immortal, he doesn't live forever until the end of the bossverse (he actually dies a few million years before that), if he isn't needed he is sleeping which makes him weaker since he can't be waken up from his sleep unless he ABSOLUTELY needs to which is so rare that you had have a better chance somehow of spitting into the sun.
Deities like Collector can also kill him in one blow.
This makes him absolutely useless but at the same time a little important.
But let me know if you think I added too many weaknesses or made characters like Collector too op against this thing.
