Which MCU hero has the highest kill count?
All the MCU heroes (from both movies and TV shows) are partying in a bar. They get drunk (yes even Cap - because Thor gave him some of his more potent stuff) and start bragging about how many foes they've dispatched.
As usual we go by onscreen feats, but in this case we also assume that any hit that looks like it should be lethal will be considered a kill, even if it's not specifically shown on screen that the victim actually died. All we need is that the hit was done on screen and we have reasonable cause to assume it was a lethal strike.
So with that in mind, which hero can claim bragging rights for highest kill count?
