There are battles with swords, spears, guns and fantastical weapons.
The violence in Black Panther is slightly more intense and realistic than other MCU films. Characters are impaled and slashed with spears and swords, the blood and wounds not always focused on by the camera.
A man is stabbed in the chest, another the same, another stabbed in the abdomen.
A man is cut numerous times during a fight
A large battle/civil war takes place with friends fighting each other. No clear if anyone actually dies, though bodies are thrown, trampled, stabbed, etc.
Security guards are shot, some at point blank range, another shot in the back unexpectedly
Two main characters are shot, one at point blank range (offscreen). Bullet wounds are shown (though not much blood)
One of Klaw's henchmen gets scared of Black Panther during a car chase and jumps out of the vehicle, only to be run over by another car. It is played as a funny scene although the man clearly dies.
