Ben Tennyson aka Ben 10,000

Ben Tennyson, nicknamed "Ben 10,000" is the fully grown Ben.

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 no longer needs to conceal his identity and is recognized everywhere as Ben 10,000, no matter what alien form he is using (obviously because he has an Omnitrix symbol on him in alien form). The name comes from the fact that now Ben has access to at least 10,000 alien forms (he says he stopped counting), he also has unlocked the Omnitrix's Master Control function, allowing Ben 10,000 to switch forms at will, without timing out.

He lives with his family,his wife Samantha,his son Ken and his daughter Cammy.
