Hero Name Victims Association

The Hero Name Victims Association (ヒーローネーム被害者の会, Hīrōnēmu Higaisha no Kai) is a group of Hero Association heroes discontent with their given hero names.

Overview
The Hero Name Victims Association consists of several heroes ranging from C-Class up to A-Class who are displeased with the names given to them by the Hero Association. Their goal is to force the Hero Association to apologize and give them new names. After recruiting Saitama, he becomes their leader.

Neo Heroes Uprising Arc
The members of the Hero Name Victims Association implore Saitama to become the executive for their group. As they claim that he is "the one with by far the most terrible name among A-Class heroes." Saitama mistakes this hero group for the Neo Heroes, saying "you must be the rumored..."

The existence of the Hero Name Victims Association appears to trouble Saitama, as he continues to ponder and consider joining them long after their first meeting. Genos mistakes this for him worrying about Sweet Mask.

The group appears outside the Hero Association headquarters while staff members are meeting to talk about the Neo Heroes. They express their displeasure about their hero names, with Saitama leading the effort. The gathering is interrupted by the announcement of several Dragon-level monsters being spotted.

Trivia

 * The group is the second group Saitama is a part of, the first one is the Blizzard Group even though he is not aware that Fubuki and her people made him their official member.
