Phoenix Man/Synopsis

History
At an unknown point in time, Phoenix Man was an actor and mascot who played an idiotic phoenix character called Bird Brain in a dark humor TV show called Animal Kingdom who always revived every time he accidentally died in every episode. Because of the dark humor, the show was canceled due to the negative reaction from the audience and Phoenix Man was fired by his cruel and unsympathetic producer.

Unable to let go of his role in the show, he refused to take off the costume and began to lose his humanity day by day, until one day, he found that he couldn't remove it and began to hear the voice of his suit. Its will caused him to fuse with the costume, turning him into a Mysterious Being and granting him the powers of a phoenix, which is resurrection.

Monster Raid Arc
Phoenix Man is first seen in S-City accompanying Sludge Jellyfish and Rhino Wrestler. The three monsters corner Mohican and Pineapple, who are carrying Narinki and his son Waganma. He watches the battle between Garou and Metal Bat and comments that Garou could be a useful asset to the Monster Association.

He then invites Garou to join the Monster Association, but his offer is rejected. He says he will overlook Garou's rude behavior this time and promises that they will meet again if Garou continues to hero hunt.

After successfully capturing Waganma, Phoenix Man retreats underground with Rhino Wrestler and Elder Centipede.

Super Fight Arc
Phoenix Man takes Waganma to the Monster Association headquarters and is commended by Gyoro Gyoro. He informs Gyoro Gyoro about monsters being cornered by heroes and asks if they should send reinforcements, but his request is denied.

Monster Association Arc
During Garou's fight against Bang and Bomb, Phoenix Man is sent by Monster Association to rescue Garou with the assistance of Elder Centipede and some other weaker monsters.

After seeing Genos, Bang and Bomb's presence, he laments that he cannot approach them to grab Garou without risking death, having seen many of his monster comrades already fall. Phoenix Man considers quitting the Monster Association and fleeing, since he would be devoured by Orochi if he came back empty-handed after sacrificing so many troops. Eventually he decides to make his move, catching the group by surprise and blowing them away with a gust of air before grabbing Garou and flying off with him. As he escapes, Genos begins to target him to blast him out of the sky, so Phoenix Man calls Elder Centipede to cover him, intercepting the attack. He then takes Garou away, informing him of their plans to take him to Orochi.

After Garou's recovery, Phoenix Man reveals to Garou that Bang, Bomb, Genos, and the rest of the heroes survived the battle with Elder Centipede.

During Royal Ripper and Bug God's observation of Garou, Phoenix Man questions Gyoro Gyoro on the purpose of sending combat types to observe Garou as both Royal Ripper and Bug God can decide to kill Garou if they're being provoked enough. Gyoro Gyoro reveals that it was a test and to facilitate Garou's growth, stating that he needs to be ravaged both physically and mentally. Gyoro Gyoro in particular is excited to see what changes Garou will undergo as a result of experiencing monsters. Gyoro Gyoro reveals that Orochi was once a human that, after countless failures and sacrifices, became the ultimate being, much to the deep shock of Phoenix Man. Gyoro Gyoro created Orochi and that only it knows the secret trick of doing so. Gyoro Gyoro mentions that with the right nourishment, Garou has the potential of becoming a second Orochi, but that if he dies then he was never good enough. While resting in his nest, he ponders that if Gyoro Gyoro could make Orochi, a former human, become such a powerful monster, so could he. Therefore, he began to dream about being a monster king like Orochi.

During the Hero Association raid, he faced off against Child Emperor, but wastes too much time mocking Child Emperor, which enables the latter to put the transparent defense wall to nullify his Beak Attack, effectively stunning him. He is then shredded to death by Child Emperor's utility backpack.

However, in a shocking turn of events, Phoenix Man overcomes his near death experience and explosively grows in power to a Dragon-disaster level. He then engages Child Emperor in battle and forces the hero to call in his trump card, Brave Giant.

Before Child Emperor can attack, Phoenix Man transports both of them into his Phoenix Space. Phoenix Man explains to Child Emperor that he intends to scout him to become a costume monster, stating that of all the heroes, he has the most darkness in him. Child Emperor denies this, saying that the other heroes look way more scary than he does, but Phoenix Man replies that Child Emperor appears to be the most stressed due to his inner desire for a trustworthy companion and an organization that makes the most of him. Phoenix Man offers to create a powerful organization with Child Emperor, one that can surpass disaster level God. He begins to hypnotize Child Emperor, telling him to reincarnate as the monster Brave Giant Man, but Child Emperor breaks out of his hypnosis and returns to the real world, punching him to the ground with Brave Giant.

Phoenix Man transforms into his Prominence Hawk Mode and knocks Brave Giant back with a barrage of strikes, remarking on Child Emperor's stubbornness and stating that he will change his mind once he sees the resurrected Phoenix Man's powers. He then transforms into Phoenix Fire Falcon Mode and attempts to critically damage Brave Giant, but Child Emperor retaliates by using his move 20000 Fold Rope Skip Grinder, knocking Phoenix Man into a pillar. Child Emperor uses Brave Giant to chase Phoenix Man through the Monster Association base, but Phoenix Man suddenly turns around and uses his Phoenix Flares to burn Child Emperor's hands. Phoenix Man then attempts another attack, but promptly flies into another one of Child Emperor's electromagnetic shields which he attached while flying. Phoenix Man asks Child Emperor to reconsider the offer, but the latter is undeterred and drives his fist into the powerful bird monster.

Suddenly, Phoenix Man transforms into Full Power 10000ºC Prominence, burning Child Emperor's hand again. Child Emperor counters by releasing Brave Giant's output limiter, breaking the floor and sending himself and Phoenix Man into freefall.

Phoenix Man and Child Emperor reach the underground waterfall, causing structural damage to part of the Monster Assocation base. Adapting again to his surroundings, Phoenix Man transforms into Phoenix Penguin Mode, leaping away before throwing a large chunk of ice at Child Emperor in his special attack Phoenix Antarctic Iceberg Attack.

Phoenix Man, Child Emperor, and Waganma land on top of the graveyard of the Subterranean People, with Saitama landing next to them. Child Emperor continues to fight Phoenix Man, but before the fight drags on, the latter transports them back to the Phoenix Space.

Phoenix Man points out that the Subterraneans killed each other, stating that their unity was weak and likening it to both the Hero and Monster Association. He then mentions the behind-the-scenes crimes of the Hero Association. Child Emperor initially brushes it off as a psychological attack, but Phoenix Man states that he's just talking as a friend, and then confides in Child Emperor about his power, stating that his Birdbrain costume granted him freedom. Phoenix Man asks if Child Emperor's heroism benefited him and requests him again to join forces. Before Child Emperor can respond, their conversation is interrupted by Saitama, who somehow found a pathway into the Phoenix Space. Saitama states that turning into a monster doesn't give someone glory and admonishes Phoenix Man for bothering children, also expressing annoyance at the level of noise from all the fighting. Phoenix Man is shown to be nervous and ultimately transports all of them back to the real world.

Phoenix Man resurrects the Subterraneans, who climb over Brave Giant, immobilizing it. He throws a monster cell through a crack in Brave Giant's machinery, stating it's medicine for the disease known as humanity. The monster cell attempts to force its way into Child Emperor's mouth, but he spits it out, stating that being a hero comes from the inside. He instructs Saitama to take Waganma and hide before unleashing Brave Giant's power by using Gigavolt Smash, which wipes out all the revived Subterraneans at the cost of self-destructing. Phoenix Man mocks Child Emperor for this move, stating that only his eye was slightly damaged, but then he begins hysterically laughing and writhing around. Child Emperor reveals that he tossed Tickle Bug #3 into Phoenix Man's suit, stating that he'll eventually suffocate from laughing too much. Phoenix Man ultimately transforms into the tiny and extremely weak Monster Chick Man before attempting to run away. He tries to sneak attack Waganma, but Saitama notices and kicks him away.
