Trumbipulor is an antagonist from Ben 10. He is from an unknown species and an unknown planet. He resembles a humanoid elephant. He talks with his trunk and his trunk has teeth.
Trumbipulor was seen having been defeated by Ben's team at the beginning of "Basic Training" for illegally trading level 3 technology. He can talk while Ben can understand him clearly with his universal translator.After Kevin mocked Trumbipulor's name, Ben mocked his resemblance to an elephant. Trumbipulor's name and design appear to be a reference to the 1980 Parliament record Trombipulation, which features a human/elephant hybrid on the cover.
In "The Purge", Trumbipulor fought Ben's team again but Trumbipulor managed to escape from custody. Trumbipulor played his first major role as the main antagonist where he was to grow to a major size. Ben was able to defeat him as Echo Echo by taking advantage of his supersensitive hearing to blast him with sound waves.
