History: (Challengers of the Unknown I #26) - A group of extraterrestrial criminals set up shop on Earth, and brought along space capsules containing alien beasts to aid the process once they hatched. The Bird-Beast would serve as general security with its' petrifying gaze, and since the aliens were weakened by sunlight and water they brought a Builder-Creature to dig underground tunnels with its' drill-like snout, and an Aqua-Beast to consume all nearby bodies of water. The gang were arrested by intergalactic police officer Kandu, but they refused to give up the location of the space capsules, knowing the beasts would cause havoc once they emerged. Kandu searched the country for them, and enlisted the aid of the Challengers of the Unknown. He went to a mountain range where a space capsule released a Bird-Beast with a petrifying gaze. Red blinding him with his shirt, and the Bird-Beast turned it to stone, but injured its' eyes. Ace used a valley to create an echo, and the confused monster crashed into a cliff. The search was interrupted by a thief who stole Kandu's tech to commit a robbery, but the Challs stopped him, and with Kandu's aid defeated the Builder-Creature and Aqua-Beast that emerged from the remaining capsules.
