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

Drive Knight is first shown at the S-Class Hero Association meeting. After the Dark Matter Thieves attack A-City, the heroes go outside to confront them. Drive Knight, Genos, and Child Emperor watch Tatsumaki besiege the alien spaceship. Seeing that his help is not needed, Drive Knight states that he has errands to run. Before walking off, he tells Genos that Metal Knight is his "enemy", and that Genos will soon find out what he means.

Super Fight Arc
After a sudden increase in monster attacks in the cities, Drive Knight confronts a group of monsters of the Monster Association. He uses Tactical Transformation: Silver to kill two of the group and demands information on the monster influx from the last.

Monster Association Arc
Drive Knight provides several pieces of extracted information to the Hero Association: After transmitting this intelligence, Drive Knight leaves to investigate the Monster Association on his own and loses contact with the Hero Association.
 * The source of the monster surge is the Monster Association.
 * The organization's purpose is to oppose the Hero Association.
 * They possess a method of turning humans into monsters.
 * The name of their leader is Monster King Orochi.
 * The suspected location of their hideout is Z-City.

Later, Drive Knight shows up to the raid and interrupts the fight between the heroes and Nyan. He ignores Nyan's inquiry about his identity and leaps towards him on the offensive. Drive Knight uses his Tactical Transformations to keep Nyan busy, leaving the cat monster unable to retaliate. The two engage in an intense scuffle. Nyan then slips into the cracks between Drive Knight's armor and attacks him from the inside. However, Drive Knight raises his body temperature to an extreme degree and burns Nyan, forcing the monster out. Drive Knight grabs Nyan in a chokehold, stabs the monster through the lower torso, and incinerates it. He announces the defeat of Nyan and walks to Sekingar with the corpse of the monster in his hand.
