Regeneration ultimate: to be able to regenerate at a unparraled speed is a form of immortality in its own right from a scientific perspective due to recovering from cellular aging and decay it would also be really hard to kill you
Kinetic energy absorbtion & redirection: basically able to absorb any amount of kinitic impact and storing the energy to redirect at a later time which could be directed thru physical contact (being able to select how much of what is stored would be preferable) this is kinda like invulnerability just to kinetic. Other things like heat, plasma sonic microwave etc etc still hurt.
Steal/transfer life: the ability to take store and give life energy (from a scientific standpoint it's taking the cellular lifespans the amount of times your cells can replicate before cellular damage prevents tangible replication. Use that stored stolen cellular lifespan and give it to other since I myself would not need it as much due to regeneration negating majority of the natural cellular decay I would suffer. From a technical standpoint I could effectively make someone live longer and recover from injury faster or the opposite depending on if I'm taking or giving.
With these 3 powers I would be a unparalleled soldier, medic, fighter, construction worker.
My ability to push past what my muscles should be capable of would problem suprise people since every time I tear the muscles it heals almost immediately.
