MCU: The Worst Thing EVERY Avenger Has Done
4. Black Panther - Attempting To Kill Bucky
If you've watched Black Panther, you're probably well aware of the fact that T'Challa is a pretty great guy. A noble king, formidable fighter and just hero, he never wavers in his conviction and rarely strays from the path of heroism. The one time that he did, however, he was pretty relentless - and understandably so.
Our first introduction to the Black Panther came in Captain America: Civil War when he showed up intent on killing Bucky Barnes. The Winter Solider had been unjustly framed for killing King T'Chaka earlier in the film and, as a result, the king's son was out for vengeance.
The fact that he later allowed Bucky to stay in Wakanda was a major step in both men's relationship and highlighted how well-developed characters they were, but once upon a time, it seemed unfathomable. Thankfully, T'Challa never crossed that line and we got to see him for the good-hearted hero that he truly is.
