Tundro is fictional characters from the animated show, The Herculoids.
A ten-legged, four-horned rhino/triceratops hybrid. He can shoot explosive energy rocks from his cannon-horn (Zandor, Tara, and Dorno also occasionally shoot similar rocks with slingshots). His natural armor-plating is exceptionally strong, similar to Igoo's rock skin. His legs have the ability to extend to a remarkable length, somewhat like stilts.
He can also spin his head at blinding speed, allowing him to drill through solid rock, and has the ability to make magnificent leaps.
