Okay so if you remember from one of the previous chapters I said that the semblance would be from a Ghost Rider game I played so pretty much whenever you kill a powerful demon, fallen angel and  humans then you'll absorb his/her soul (if you don't use the Penance Stare) and gain all of their powers.I haven't come up with a name for it but I'll update from time to time whenever you gain new powers. But here are your powers currently.

-Electrical Attacks(Use electricity in different ways of attack)

-Electrical Healing(Can heal yourself and others through electricity) 

-Enhanced Strength(Stronger than peak condition humans)

-Enhanced Speed(Faster than bullets and normal cars)

-Electricity Detection(You can sense where electricity is)
