|First Appearance||Ben 10 Alien Force: Vilgax Attacks|
A beautiful, mountainous, and lush world, Terradino is home to a vast and varied number of diverse animalistic alien species, many creatures great and small. Tragically, all these different species have not evolved to live here together peacefully. Warring factions in every group constantly seek to wrench control of society for themselves. However, the Vaxasaurians have been able to temporarily restore order through their sheer physical superiority. When seen from space, Terradino resembles Earth.
Terradino's name is a play on the words terra, the Latin word for earth or land, and dino, the Latin word for feared, meaning "Feared Land".
- Terradino is the first named planet that is home to two of Ben's aliens.
