Bofoi

Dr. Bofoi (ボフォイ博士, Bofoi Hakase), also known by his hero alias  Metal Knight (メタルナイト, Metarunaito), is the S-Class Rank 6 hero for the Hero Association. He offers many services for the hero association, such as weapons sponsorships and facility construction.

Appearance
Not much is known about Bofoi's real appearance, as his full face has only been shown in the webcomic. 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. Bofoi acts mainly through the use of his robots controlled from a safe distance. Two of his robots have been displayed. The first is 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, possibly used for reconnaissance.

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 little 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 Drive Knight's warning to Genos, anything about Bofoi remains a mystery.

He is also aware of the corruption inside the administration of the Hero Association, but isn't at all above using their pettiness to his own gain.

When dealing with monsters, he is very cautious and pragmatic since he can see through the provocation of the Monster Association as a trap to destroy the majority of heroes in the Hero Association. However, at the same time, his pragmatism also makes him extremely ruthless, since he suggests planting bombs at the weak points of the Monster Association hideout to kill them while disregarding the life of the hostage child of one the main sponsors of the Hero Association. As the result, the Hero Association rejects his plan, and even Child Emperor feels disgusted about this.

While he comes off as cold, practical and calculating in demeanor, Bofoi's actions and decisions stem from what appears to be fear of an unknown evil that is lurking in the shadows. His particular fear is shown towards the Monster King, who eliminated his robot probe in an instant. Bofoi himself even stated it wasn't the Monster Association so much that he was afraid of, but Orochi.

The moments where Bofoi shows care for others are rare. During his attack on Elder Centipede, he stopped to warn two heroes to get out of his field test. Though this was mostly for his own interest rather then acting heroic. His reasoning to bomb the Monster Association can stem to his desire to keep his fellow heroes alive in order to further protect humanity.

So far, the only person Bofoi shows some level of care towards is Child Emperor. Bofoi was willing to reveal his personal fears to Child Emperor and went out of his way to warn him about the dangers lurking in the shadows, going so far as to even give him some personal advice on how to stay alive and telling him to take care.

His justice involves sacrificing a few to save the many instead.

'''The following section contains Webcomic spoilers. You have been warned manga-only readers.''' After Saitama destroys all of his robots, he begins to gain interest in the Caped Baldy and begins to spy on Saitama intensively, since he considered the latter to be a potential threat to his ranking in the future.

He harbors some resentment towards Saitama due to being reprimanded by the Hero Association staff for his unreliable defense against monsters which Saitama destroyed and blamed on its malfunction.

Abilities and Powers
Being a S-Class hero, it can be assumed that Bofoi is very powerful, though he got to that position due to his brain power and the strength of his weapons, as opposed to his own physical strength. According to Gyoro Gyoro, he is one of the four heroes that could beat Elder Centipede. Despite this, he was unable to damage the monster when he fought it with his drone. However, it is noted by Phoenix Man that the full extent of Bofoi's military might and weaponry is unknown, even to the Hero Association, which is why they fear his potential betrayal, as he would pose a huge threat.

Fighting Style
Mech Pilot: Bofoi is said to have a reputation of using powerful weaponry to pulverize his opponents and everything else in the vicinity. He uses for his missions and experiments various remotely controlled robots equipped for the occasion. He also appears to have great skill in piloting his favored battle robot. With this form of combat, Bofoi has the advantage of not putting his own life at stake, as he controls his robots from a safe distance.

Miscellaneous Abilities
Genius Intellect: Bofoi possesses a genius-level intellect, which enables him to create highly advanced machines and weapons.
 * Master Scientist and Inventor: He created various defense systems for the Hero Association, such as a nearly indestructible shelter and various powerful weaponry.
 * Master Architect: He was also able to rebuild the Hero Association's HQ in A-City in a few days, proving great architectural knowledge.

Equipment
Robots: (ロボット, Robotto) Given his preferred form of combat, Bofoi has a vast amount of remotely controlled robots with built-in weapons, which he also uses for experimentation, scouting, and rebuilding.


 * Battle Robot: (Unofficial Name by HA) (戦闘ロボット, Sentō Robotto) Bofoi's favored remotely controlled robot, which he uses in combat. It is a large silver-colored robot with multiple cannons attached to its back. It has a distinct set of three circular marks on its "face." Bofoi is capable of communicating through this robot. It is first shown when Bofoi was testing its weapons against a colossal meteorite.
 * Flight: Bofoi's battle robot is shown to be capable of flight. This is due to the multiple jet propellers incorporated in its design.
 * Missiles: Bofoi's battle robot is shown to be able to fire off massive volleys of large, powerful missiles. They are noted by Genos to possess great destructive power.
 * Suction Pads: The battle robot possesses multiple suction pads inside its body, which it can extend out in order to cling onto something. Bofoi first used them on Elder Centipede, when the latter retreated with its comrades.
 * Durability: The strengths and limits of the Battle Robot's defensiveness and durability have so far not been shown. However, when Bofoi was explaining his encounter with the Monster King, he placed an emphasis on the fact the Monster King was able to penetrate through the robot's hands and body in a single strike. This can suggest that the Battle Robot has considerably strong durability.


 * Bofoyrobot.png Reconnaissance Robot: (Unofficial Name by HA) (偵察用ロボット, Teisatsu-yō Robotto) A smaller, roughly human-sized robot with no visible weaponry or armor. Like the favored battle robot of Bofoi, it has a distinct set of three circular marks on its "face". Bofoi, like with his other robots, is capable of communicating through this robot. It was first shown after the battle against the Dark Matter Thieves, coming out from a pod.


 * Construction Robot: (Unofficial Name by HA) (エ事用ロボット, E koto-yō Robotto) A colossal four-legged robot with a vast amount of drones stored inside and a large cannon mounted on its front. Bofoi, like with his other robots, is capable of communicating through this robot. It was used by Bofoi to rebuild the Hero Association's HQ after the battle against the Dark Matter Thieves. The robot was seemingly unhampered by Tanktop Master's attempt to halt its movement, and later flung the S-Class hero far away with little effort.
 * Small Recovery Robots: (回収用小型ロボット, Kaishū-yō Kogata Robotto) The construction robot has multiple small recovery robots in it, which it can send out to recover materials. The recovery robots are ball-shaped and have propellers, which enables them to fly. The are also able to extend arms to collect debris.
