A.T.O.M.: Alpha Teens on Machines

The Teens go for an innocuous visit to the local museum, where they are unexpectedly ambushed by rogue ninjas. Also there is Dragon, a former ninja enemy of the team, who appears to be part of a conspiracy to steal the most powerful sword on the world, conveniently on display in the museum's gallery. With Lee, their financier and de facto guardian, out of town, the group borrows one of his jets to escape to Hong Kong in hopes of tracking down and returning the sword from the cloaked assailants. Along the way, they discover that Dragon has snuck to Hong Kong with similar intentions, and thus a new and surprising team is formed with the collective intention of keeping the world's most powerful weapon out of the wrong hands.
