Monster Information

"Roar! Think fire is enough? Wait until this yard becomes one giant Atomic Fireball!"

Teratorn is the first flying monster to be introduced to Backyard Monsters. It takes a lot of Goo and time to make, but the overall result does not disappoint, as Teratorn is very bulky. Teratorn can only be hurt by the Sniper Tower, Tesla Tower and Aerial Defense Tower. The Sniper Tower and Tesla Tower doesn't do much to a swarm of Teratorn, but Teratorn should beware the Aerial Defense Tower. They don't trip Booby Traps because they fly and can't be attacked by monsters except D.A.V.E.s with rockets from the Monster Bunker, Fomor, and Eye-ras with Air burst. Also, Teratorns can fly over Blocks.
