Ben Tennyson (Alien Force)

Benjamin Kirby Tennyson, or simply just Ben Tennyson, is a 15-year-old hero who has grown significantly since his childhood adventures. Now wielding the recalibrated Omnitrix, he's a seasoned defender of the universe, balancing newfound responsibilities with his inherent adventurous spirit.

== Appearance == At 15, Ben has matured physically. He's taller and leaner than when he was 10 years old. He wears a black short-sleeved T-shirt, blue jeans, a green jacket with white stripes on his left sleeve and the number 10 on the right, white socks, and black and white Converse-style shoes. His hair is also shorter than when he was 10/11 years old. The Omnitrix, which would later be the Ultimatrix during the events of Ultimate Alien, is prominently displayed on his left wrist, having recalibrated to a sleeker, watch-like form.

== Personality == Ben's experiences have matured him, but he still retains the core traits that define him as a hero. He possesses a resourceful and determined spirit, enabling him to confront formidable challenges with unwavering resolve. Driven by a strong sense of responsibility and a deep commitment to upholding justice, he is dedicated to protecting the innocent.

Ben is undeniably adventurous and always eager to explore new worlds and face the unknown. He approaches situations with confidence and a sense of humor, often using wit and banter to lighten tense moments. This lightheartedness does not diminish his dedication to his heroic duties; instead, he has learned to balance his playful nature with the seriousness of his responsibilities, showcasing newfound maturity.

His years of experience have sharpened his strategic thinking and leadership skills, allowing him to effectively guide his team and make crucial decisions under pressure. He is no longer the impulsive child he once was but a thoughtful and capable hero who understands the weight of his actions.
