Tiny

Tiny is the name given by Ben to a unnamed baby green alien that appeared in the episode Unearthed after she was roaming around in Bellwood and wrecking stuff. After Ben, Gwen and Kevin found her, they had a battle with her thinking she was working with the Highbreed until Gwen figured out she was just a baby. They later defended her against the DNAliens which were after the power coupling, which she had detached earlier. She later snuck in the cave to the spaceship to where her parents were in suspended animation in stasis Pods for half a century because of the Time Machine experiment that happened in 1952. Throughout the episode Tiny and Gwen build a close relationship. She could see Gwen's Anodite form and her first words were "Gwen".

Powers and Abilities
Despite being only a baby alien, Tiny is very strong easily ripping lamp posts out of the ground, carrying the DNAlien power coupling (which is very heavy) like a baby's rattle, lifting up Kevin's car and taking a bite out of it and being able to hold her own against a normal sized Humungousaur.

She can also see Gwen in her Anodite form while no one else could (though it is possible her parents could see it too but it remains unknown.)
