The Green Aliens are strange green aliens that live on a green planet (possibly Venus). They use pitchforks and torches in battle. They are seen in Troq and Transformation. In Troq, the green aliens are known creatures to be attacked by an army of Locrix. In Transformation, they chased Starfire out of their planet and are grouped together like an angry mob. When Robin and the other members are searching for Starfire, the green aliens didn't tell them where Starfire went, but the green planet came to life and it T-Ship got chomped in the planet's jaws and the green planet spits the shuddle out where they'll find Starfire.
