Very stylised video game violence.
All the violence in the film is intentionally comic and not intense.
Stylized, hyper-kinetic action. When people are defeated, there is no blood, since they become coins. All fights are comic, with words like "THUD" or "KPOW" when someone hits a wall, etc. It is meant to resemble a comic or video game.
Scott punches Roxy in the boob.
In one instance, Scott is very briefly seen slicing off a man's leg with a sword (It explodes into coins, followed by the man a second later).
Scott slashes an Gideon across the face, leaving a small cut.
Todd flings a Scott towards a tower, and the young man smacks the wall, falls through scaffolding, and finally lands on the ground. He defies physics by not being injured at all.
Todd also flings Scott up in the air, then the young man lands on a pile of garbage. Again, no injuries.
Knives battles with swords. She doesn't injure anyone with them.
Knives and a Scott play a Ninja Dance-Revolution type arcade machine. A very brief image of a ninja kicking off another ninja's head, with some blood and gore, is flashed. "Blink and you will miss it" moment.
Some slapping between characters and mild arguing. A few characters can look menacing.
