Looking for inspiration on a character build.

Fire Force has a character named Charon the Reflector. His whole shtick is absorbing and redirecting incoming force. I am not looking to do a 1-1 character based on Charon, but I do like the idea of a character who can take a strong hit and then deal either the same amount of damage or an increased amount of damage (up to a threshold) to the offender (like Hellish Rebuke) or redirected to a new target. It can be either for a PC or as a stronger enemy (boss or boss's lieutenant, for example). I'm mostly curious to see what you guys can come up with.
