Firstly, these both appear to be Arrancar class characters, not hollows. Hollow's are more common and have finite number of abilities. I would look over the description provided in the topic post.

For your character, MC; I'm fine with the majority of his abilities with the acception of Silence, Summoning, and Reform. Silence, regardless of how infrequently it is used, is a form of controlling another character which is a roleplay taboo. For Summoning, though you can open a portal to hueco mundo and attract hollows with spiritual pressure, simply materializing a hollow goes against the natural order. It wont hurt to go hunting. As for reform, vital organs aren't able to be regenerated as they provide the basic needs to generate spiritual powers. Rapid regeneration for all other parts of the body however is fine. Beyond this, MC looks ready to be accepted.

For Light; Extreme Regeneration is a no no for the same reasons being my explanation from Reform. Even the most powerful forms of regenerations have a limit. Also it takes away from your other abilities. Extreme Strength or Kinetic Combat. I would pick just one. Personally I like you Kinetic Combat ability better then just sheer strength. Maybe instead of flat out power, Light's power could scale with her kinetic speed. So in the beginning of a combat situation, she would be relatively slow and weak, but can rise to dangerous levels as the battle continues.

I still want to have balance among characters within the story. As I said before, traits that are considered OP should be avoided or at least be countered by an equal weakness.
