Bofoi/Relationships

Child Emperor
Bofoi has cordial relationship with Child Emperor. He cares about him enough to warn him of dangers of others and to amass his own strength for himself.

Bofoi and Child Emperor are two of the only heroes whose intelligence and reliance on their own technology are their strength, nor do they possess any superhuman attributes or abilities (disregarding Child Emperor's above average human abilities).

Child Emperor appears to be one of the few heroes that Bofoi frequently keeps in contact with, as he has displayed multiple moments of temper tantrums that Child Emperor is used to dealing with. Beyond that however, their relationship appears to be a professional one rather than an intimate one.

Child Emperor and Bofoi have contrasting mindsets due to their differing personalities. Child Emperor has a caring side that makes him think of the well being of others in a given situation, while Bofoi focuses on a more cold and calculating method in order to achieve better results without excessive consequences. This creates a conflict between the two when proposing strategies in a given situation.

Child Emperor seems to hold some level of respect for Bofoi. Upon hearing of him not partaking in the rescue and ambush of the Monster Association, Child Emperor was shocked and attempted to make Bofoi reconsider, though he would find some of Bofoi's methods to be more excessive than it has to be. Bofoi seems to hold Child Emperor to some level of regard, as he expected Child Emperor to analyze the situation better than he did and lectured him about his failings and the potential of the Monster Association threat.

Child Emperor was also an assistant to Bofoi for an unknown amount of time in the past.

Drive Knight
The relationship between Bofoi and Drive Knight is currently unknown. However, Drive Knight appears to know Bofoi enough to not trust him.

Saitama

After Saitama destroyed his robots, he was shocked by his power and decided to look at Saitama achievements. Bofoi found out that Saitama got promoted too fastly, but his achievements are small. Bofoi realized that Saitama is as strong as an S-class hero or even more stronger. He decided to spy at him, in case Saitama becomes his enemy.

Bofoi also gained a grudge against Saitama for destroying his robots and Hero Association blamed it on him.

Saitama
After Saitama destroyed Bofoi's defense system around A-City, Bofoi developed a grudge against him for being reprimanded by the Hero Association staff.
