The First Order vs the Avengers

[Peelee]

Lethal blasts never hit organic main characters. Stun blasts almost always do.

Lethal blast hit Leia in the shoulder on Endor. "Lethal" in the sense of "full-powered blast, not a stun blast."

ETA: Also, the stun blasts in the new trilogy are significantly more likely to be lethal in the sense of "can freaking kill you." Old stun blasts just dropped you, which makes sense. New stun blasts throw you across the room, which should right off the bat break bones and can very likely kill if you hit the wrong thing the wrong way. All for a cheap laugh.
