Blue

Blue is the founder and top hero of the Neo Heroes. He is purportedly the son of Blast.

History
16 years prior to his introduction, Blue was supposedly born to Blast and an unknown mother. Sometime prior to the Supreme Hero Arc, he created the Neo Heroes and recruited several people to form its ranks.

Supreme Hero Arc
Blue is first shown chasing Saitama, who is running away from the battle that just transpired in I-City with a monsterized Sweet Mask in tow. Worried that he is going to fall behind, Blue decides to use his one-time weapon, stating that he needs to remove his suit's limiter. However, he is intercepted by Genos, who orders him to stop and questions him on his actions. Blue frustratedly asks Genos why he would interfere in his attempt to catch Saitama, also questioning Genos on the motives of the Hero Association and Saitama's identity. He begins to remove his jacket, warning Genos that the situation could escalate to violence if he did not cooperate. Genos remarks on the high energy signature he detects on Blue's forearm, stating that it is prohibited for individuals unregistered in the Hero Association to carry weapons of that nature. Blue retorts that Genos himself resorted to vigilantism prior to registering as a hero, stating that he did a background check on every powerful hero. Blue then introduces himself as the number one Neo Hero. Genos, upon realizing this, states that there is no reason for them to fight and then begins to walk away. Blue demands to know what Saitama will do with Sweet Mask, but Genos offhandedly states that he does not know before leaving. Blue contemplates the corruption of the Hero Association.

Later, Blue is shown sitting in the back of the Neo Heroes leader meeting and is introduced by McCoy as the catalyst for the organization's creation. Blue states that he created the Neo Heroes to show the world what heroes truly are, adding that this was no easy task and that they would have to give it their all. 'A' expresses his surprise at Blue's young age, and Zaedats remarks that Blue is special due to him being Blast's son.
