Bofoi

Bofoy (ボフォイ博士, Bofoi Hakase) is an S-Class, rank 6, superhero for the Hero Association. He also goes by the hero name Metal Knight (メタルナイト, Metarunaito).

Appearance
Not much is known about Bofoy's real appearance as his full face has never been fully shown. From what has been seen he has white hair and a large nose. He is also seen wearing a lab coat over his blue shirt. Bofoy acts mainly through the use of robots controlled from a safe distance. Two of his robots have been displayed, the first a large unit capable of flight with a high level of firepower attached. The second was much smaller, roughly human sized and with no visible weaponry. Each robot shown has had a distinct set of three circular marks on its "face".

Personality
He appears to have an avid interest in any form of high technology, as shown when he sent one of his robots to collect remnants or look for anything that might be useful in the wreckage of the Dark Matter Thieves' ship. Despite being a hero, he has no compassion for others if it won't benefit him. Even when a meteor is about to strike Z-City, his only concern is the reliability of his new missiles. Because of Engine Knight's warning to Genos, anything about Bofoy remains mysterious.

Giant Meteor Arc
As Genos prepares to take on the giant meteor, a large robot flies by and lands on a nearby building, shortly followed by Genos who then reveals the large robot is in fact an S-Class hero for the Hero Association. Genos introduces himself and asks Bofoy for his help, but Bofoy refuses, stating that he is only there to test out a new weapon, and that he would prefer to be called Metal Knight, as it is weird to call a hero by his real name. He then reveals that he isn't even in Z-City, but is instead using a remote controlled robot from a safe distance away. Genos then runs off to a better place to stop the meteor, but stops as Bofoy fires a volley of large missiles which converge on the meteor and cause a massive explosion. This, unfortunately, is not enough to stop the meteor which bursts through the cloud of smoke cause by the explosion much to both Genos and Bofoy's surprise.

Alien Conquerors Arc
After Lord Boros's defeat and the fall of the Dark Matter Thieves' spaceship, Bofoy, through one of his robots, appear in the ruins of A-City to collect the remains of the spaceship. Genos then confront him asking what he will do with it, and Bofoy answers that he will use their technology to make new powerful weapons, that are needed for the sake of peace. It is also revealed that Genos and Bofoy may have a connection, as Engine Knight tells Genos that Bofoy is his "enemy".

Bofoy sends a giant robot commandeering multiple drones to rebuild A-City into the Hero Association's new HQ, taking only seven days to do so from the estimated ten years.

Centipede Arc
While Elder Centipede wrecks havoc to S-City, Bofoy arrives and attacks Elder Centipede. Despite his powerful set of missiles, Elder Centipede only get's annoyed. Bofoy see this as an opportunity to collect Elder Centipede skin after his defeat to build more weapons.

He then tells the Mohican and Pineapple to leave because of the potential destruction his weapons can cause.
