Brotherhood

The Brotherhood is an evil organization bent on world domination and the elimination of heroes founded and formerly led by Brian Death, his associates Lady Death, General Death, Monsieur Mallus, and Dr. Cyanide, with Ghost doing their deeds, serving as the main antagonists of Season 5 and the archenemies of Sebastian Harper.

Their plan was to eliminate every potential threat like the Legends and take over the world. Hiring and disposing of certain employees, they have been attacking Bianco Academy for years, until focusing on West City and are responsible for the death of Janet Roane. After Ghost seemingly took out the Legends, he lead an assault on the city and caused chaos, capturing the Legends, the Arsenals, Team Silver, and Team Zero. After defeating Ghost, who revealed the whereabouts of his friends and the existence of the Brotherhood, Sebastian lead a final assault against the Brotherhood, freeing his friends, avenging Janet, and ending their reign of terror.

After the fall of the Brotherhood, however Luke Richards gathered the remaining members and currently continue the legacy of the Brotherhood.
