Ben 10

Its hero time! And anyone can be a hero. Ben Tennyson was an ordinary ten-year-old schoolboy until the one Summer day that he came across a mysterious device called an omnitrix at the site of a crashed meteorite. It would change his life forever. He put the strange watch-like device on his wrist and he discovered that it allowed him to transform into an endless choice of different alien forms which each have their own unique powers and abilities. However, in those different states he still keeps his own ten-year-old mischievous personality. With help from his cousin Gwen and Grandpa Max he is able to continually defend against various threats to save the day and consequently the world. Although she is the same age as Ben, Gwen is usually the voice of reason and sometimes has to stop Ben from rushing into situations without thinking things through and planning ahead. The evil warlord, Vilgax, is a common enemy to Ben, as he will stop at nothing to retrieve the omnitrix, which he aims to use as a weapon.
