Neo Heroes Saga[]

Psychic Sisters Arc[]

After the threat of Garou and the Monster Association had passed. Fubuki, along with members of the Fubuki Group, visit Saitama at the new A-City base of operations for the Hero Association.

He's silently livid at the fact that said hero whom would never agree to work under their leader had recently become an A-Class Hero. Regardless of that, he would cater Saitama alongside Fubuki to the prison area of their escort's new home base. Whilst the two meet an old friend of their leader's, Mountain Ape and the rest would stand guard.[4]

Much too their horror however they are beset by Tatsumaki at the prisons entrance.

Ape and the remaining few of his colleagues still conscious would attempt to bind the S-Class hero using a psionic hold taught to them by their leader. It was less than ineffective, as the tornado of terror just as easily blew right through the lot of them as she did before they erected they're psionic defenses.[5]

Appearances in Other Media[]


A New Wind Blows[]

Mountain Ape makes his first appearance shouting in a blow horn, telling Banero to surrender. The Blizzard Group surround Banero in an alleyway. After a short conversation with Eyelashes, the criminal decides to attack with a bundle of Molotov cocktails, but the Blizzard group is able to quickly subdue the criminal. The group then discuss how to split the credit. Eyelashes suggests that the newcomer should receive no credit as he didn't contribute in the fight.

During the fight against Demonic Fan, Fubuki and her underlings try to defeat the Mysterious Being but are easily beaten by it and are subsequently rescued by Fubuki's sister, Tatsumaki who takes her away after defeating the Fan.

Struggle of the Blizzard Group[]

The Blizzard Group is in need of a new car. Fubuki suggests that there are plenty of flyers nearby and if they, the Blizzard Group, work together they should be able to earn 5 million, enough to buy a new car.

Like the others, he is shocked when Fubuki said she meant to go after criminals bounties for the money.
