Brin gained his super powers from experiments conducted on the fictional element Zuunium by his father, Dr. Mar Londo. A jealous android assistant of his father, named Karth Arn, switched identities with Brin, but the plot was eventually revealed when "Lone Wolf" first meets the Legion. He was an initial graduate of the Legion Academy. Brin was thought dead for six months, but had actually been kidnapped by the villain Tyr (during his captivity he gained more lupine features). He had a long standing romance with fellow Legionnaire Light Lass. They eventually broke up due to a misunderstanding when Light Lass found Timber Wolf embracing Saturn Girl on a frozen asteroid. In the fourth Legion of Super-Heroes series (known as V4 to fans), The Legion hid Brin's identity from most due to a desire to protect his friends from finding out what had become of him; when a young girl named Gemini discovered this, she "rescued" Brin from his teammates as they traveled the galaxy in search of Darkseid (who was holding Gemini's brother hostage). Intrigued by Gemini's kindness towards Brin, Darkseid restored Brin to normal in exchange for Gemini killing Darkseid. Brin renounced the Legion, horrified at their treatment of him, and fled using a time machine back to the 20th Century. There he befriended the "New Blood" super-hero Jamm and was experimented on again by mad scientists who sought to create their own "Timber Wolf". The process transformed Brin again, making him physically wolflike (with brownish black skin limited fur on his body) but allowed him to retain his mind. Timber Wolf returned to the future and ultimately reconciled with the Legion. In the Post-Zero Hour reboot, Timber Wolf was introduced in the Legion Worlds miniseries. He is a rival gang leader to Ultra Boy in this continuity. There is a love triangle between himself, Ultra Boy and Apparition, as he met Apparition while Ultra Boy was part of the team lost in the Second Galaxy, and formed a strong connection with her. Timber Wolf later realized his feelings for Apparition were only those of a friend, but Ultra Boy remained jealous.
