The Alien Heroes! (Ben 10 x Male OC)

Duncan Baxter is a 14 year old boy who, along with his closest friend Ben Tennyson, goes on a cross-country summer vacation, with Grandpa Max and Gwen Tennyson. On their first night camping in Grandpa Max's RV, which is affectionately named as the "Rustbucket," both Duncan and Ben find an alien pod with two mysterious watch-style devices named the Omnitrix and the Ultimatrix. The two devices then permanently attach themselves to their wrists, giving them the ability to transform into a large variety of alien life-forms, each with its own unique set of unique skills and many awesome powers. Now armed with new alien superpowers, Duncan has to learn the responsibilities of being a hero, whilst also mentoring Ben along the way. During their long vacation, the group are soon attacked by various enemies ranging from space aliens to supernatural entities.

Along the way, Duncan and Ben will have to face their toughest challenges whilst also conquering their deepest fears as well as growing stronger in the process.
