Guardians Of The Galaxy Vol. 2: 12 Biggest Questions It Leaves Unanswered

11. Are Peter's Celestial Powers Totally Gone?

The Question: By killing Ego, Peter essentially made himself mortal once again, but are his celestial powers completely gone, or is there something left behind?

The Likely Answer: While it's possible that his prior handling of an Infinity Stone and unconventional origins may have left some residual supernatural power, it makes a lot more sense character-wise for Peter to now be strictly mortal.

Considering The Avengers already has its share of God-like characters, he's probably powerless from now on, as was the trade-off of his decision to kill Ego. If he's still got powers that can be pulled out in a desperate deus ex machina moment, it somewhat undermines that choice.
