Ben 10,000 (Original)

Ben Tennyson, nicknamed "Ben 10,000" is the fully grown Ben, from his current future.

Ben 10,000 has become a full-time hero. He is tall, more muscular, and sports a full-beard. The Omnitrix has also changed in appearance, becoming bulkier and more gauntlet-like in shape. He is recognized everywhere as Ben 10,000, no matter what alien form he is using (because his aliens have an Omnitrix symbol).

His nickname comes from the fact that now Ben has access to at least 10,000 alien forms (he says he stopped counting).
