Some robots are destroyed in violent ways, such as getting blown up, crushed, shot and having their motherboard torn out.
Blood is very briefly seen in an episode where Constantine pulls quills out of Kamikazi's hand.
Violence appears in every episode where the main character fights with his enemies.
However the violence is at a good level for young children with nothing too violent or gory.
No gore.
The human characters such as Robotboy's friends appears in near-death situations but Robotboy always manage to save them at the last minute.
