Drive Knight/Synopsis

History
Drive Knight was named by the Hero Association after a direct request from himself.

Alien Conquerors Arc
Drive Knight is first shown at the S-Class Hero Association meeting. Shortly after the attack from the Dark Matter Thieves, he alongside Genos and Child Emperor observe Tatsumaki besieging the thieves spaceship. As this happens, he states that he has errands to run. Before walking off, he mentions to Genos that Metal Knight is not to be trusted, and that Genos will soon find out why.

Super Fight Arc
Drive Knight takes care of several monsters and asks one of them for information about the current invasion.

Monster Association Arc
Drive Knight managed to retrieve information from the monster and transmit it to the Hero Association Headquarters, revealing that the Monster Association Headquarters may be in Z-City. He apparently went there on his own and is presumed to have been defeated since the Association lost contact with him.

However, it is later revealed that Drive Knight is perfectly fine, and he arrives at the battle against Nyan to fight the Dragon-level feline.
