About A.T.O.M.

A.T.O.M. follows test teens Axel, Shark, King, Lioness and Hawk with joining vehicles across two seasons and 52 episodes in Landmark City. Season 1 from 2005 sets the JoLand contest, the Mu-team crooks, and the join up pattern with Mr Lee tech and Paine villains.

Season 2 from 2006 to 2007 moves to the Serpent Tail plot, the Reaper war, and the final join with new masters and Terrashark mounts. The Flesh and Vinnie Rossi fights carry arcs. Watch in release order since vehicles stack. The run closed in 2007 with no revival announced.

Good to know

There is no separate chronological order for A.T.O.M. worth listing, since release order matches the contest from trials to tail. The join ups repeat on purpose each fight with vehicle codes, so the team lands in order. Watch season 1 first for the vehicle rules, then season 2 freely in order today for full arcs.
