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

With his friends all going their separate ways for the holidays, Axel, with no family of his own to go home and celebrate alongside, experiences a series of perpetually escalating events. After mistaking an accidental collision for a threat and subsequently being confronted by a genuine ninja whose skills are comparable only to his own, he remarks at what a "weird day" he has found himself in the middle of. Axel's comrades offer their wholehearted support in the compromising weather, though he vehemently and repeatedly rejects their assistance. They entire crew ultimately finds themselves entangled in the same martial arts dilemma as Axel, despite his attempts to handle his equally adept opponent alone.
