Growler was a humanoid bear-man and one of the many genetically evolved experiments conducted by Project Moreau in the 1940s.
Of the three, Growler was the most passive, despite his prodigious size and strength. He had a sharp, analytical mind, but was not adverse to using the strength his body afforded him should the need arise.
Growler and the other Wild Men befriended Superboy when he mysteriously appeared on the island and helped him to liberate several human slaves from the trader known as Sacker. Afterward, they accompanied Superboy back to his home in Hawaii and assisted him in repelling an invasion of Pearl Harbor perpetuated by the bat-woman Nosferata and Killa the gorilla. Although Pearl Harbor was saved, Nosferata manipulated her way into becoming the new queen of the Wild Lands. As such, she forced the Wild Men into exile, and they were never allowed to return to the land of their birth.
Growler and the others then embarked upon a quest to locate Superboy's lost love, Tana Moon.
