After becoming stranded on Earth, an unidentified alien befriended young Paddy McGinty, and used its native shapeshifting ability to blend in by assuming various forms, most commonly posing as a goat.
Paddy McGinty’s Goat featured throughout the entire short run of IPC’s weekly comic Jet. By the modern day, as shown in Rebellion’s The Vigilant, the “goat” had been forcibly enslaved by the villainous Von Hoffman, who forced it to fight his enemies.
