"I know I look stupid, but give me a break. *RAABAHK!!!*"-
PlanetDactyl is Alex's (AL 12's) Galilean and Astrodactyl's Species Fusion Hybrid Form.
He can only be created from the Biomnitrix.
His appearance is a mix of Gravattack and Astrodactyl.
A rocky humanoid pteranodon with spikes on his arms and shoulders with a red core on his stomach and a V-shape mark on his chest. There's goggle-like rock points on his forehead on top of the eyes.
Same as Alex's personality.
Core breaks and blows him up along with anyone 20 miles away.
Wings pinned down.
"EAT LASER BEAM SUCKER!!!" *SQUAWK*
- He is based from Gravadactyl. A unused concept art character that never was used on Ben 10 Omniverse.
