Histroy
As children growing up in Australia, Baran Flinders and his sister Selinda received nothing but mockery as their unique abilities developed, she could transmute elements, while he exhibited terrifying strength. The world-renowned scientist Dr. Helga Jace taught them how to control their talents, whereupon they created the villainous identities of Mammoth and Shimmer and joined Doctor Light I, Gizmo, and Psimon as members of the Fearsome Five. Mammoth has clashed with the Teen Titans and Superman, both with the Fearsome Five and on his own. Devoted to his sister, Mammoth suffered deep psychological trauma when Psimon killed her. With the help of Doctor Sivana, however she was resurrected and the Fearsome Five reunited. Mammoth joined Alexander Luthor's Secret Society of Supervillains along with Psimon, Shimmer, and Jinx.

Mammoth is seen in multiple issues of Salvation Run on Team Joker, from getting in an argument with Ibac to punching Martian Manhunter in the face.

Mammoth has a run in with Bane, Scandal, Deadshot and Ragdoll when they broke into Alcatraz trying to free Tarantula. They battled with Mammoth with little success and ended up enraging him even more. Scandal finally puts him down by remotely piloting Black Manta's ship through the wall and ramming him.

Powers
Baran is immeasurably strong and is partially invulnerable. He appears quicker than his considerable bulk would imply but lacks any developed skills as a hand-to-hand combatant.

Baran's durability has been shown to fluctuate through the years, at one point Wonder Girl and Starfire could not physically harm Baran with some of their best attacks, and at other points he's been able to be physically harmed by Bane.

Also, Baran appears to be emotionally underdeveloped and has a very strong attachment to his sister. He can become uncontrollable if separated from Selinda.
