The Fearsome Five was a villain group founded by members of the H.I.V.E. organization. They were only featured in the Teen Titans Go! comic series. Jinx, Mammoth, and Gizmo appear as H.I.V.E. Academy students, and later members of the H.I.V.E. Five. Doctor Light appeared as a minor villain constantly annoying the Titans. Psimon also appeared in the fifth season, capturing Raven for the Brotherhood of Evil. The only member never seen was Mammoth's sister Shimmer.
Doctor Light would form the team due to constant losses to the Titans. He would advertise in a super villain's newsletter: The Underworld Star.
Psimon would eventually take over as leader and kick Doctor Light out. Psimon was a servant of Trigon and made the Team help him, but his failures made Trigon banish him to another dimension. The members would soon find and save Psimon. The members would later kill Psimon for his alliance with the superhero Moniter. Psimon was alive though and tried to destroy his former teammates, he would attack Gizmo, Mammoth, and Shimmer, but only Shimmer died.
A man named Dr. Sivana (enemy of Captain Marvel) would reunite the team and revive Shimmer. Dr. Sivana would eventually get fed up with the team and leave them after killing Gizmo. The Last appearance they made was working with the Society of Supervillains before being sent to a Prison Planet.

The Fearsome Five made an appearance in the issue The Fearsome Five. In this issue, Doctor Light and Psimon were looking to recruit some of the former H.I.V.E. students (such as XL Terrestrial, See-More, Angel and Kyd Wykkyd), some villains that worked solo (such as I.N.S.T.I.G.A.T.O.R.., Cinderblock and Adonis) and some never before seen villains. They all gathered and Doctor Light and Psimon pitted the villains that were interested in a position on the team, and those who weren't. However, this didn't go as they hoped, and all the villains ended up knocking each other out. Last to arrive were Gizmo and Mammoth, who sent a letter to Jinx (who turned good by this point) asking her to come back. Jinx went to the meeting and formed the Fearsome Five with them, but she was actually faking it. The Fearsome Five tried to take over Titans Tower, but because Jinx revealed her plan, the Fearsome (now Four) went to jail.
