 * Radiation Meteor: A flaming meteor falls on the track which deals 10 HP damage to every tower caught in its 260px explosion and leaves a crater with 210px diameter on the track for 10 seconds which deals 1 HP damage every second.
 * Atomic Fusion: Shoots a huge bullet which splits into 2 big ones that split into 3 medium ones that split into 4 small ones which split into 5 tiny bullets which then make a small explosion. The huge bullets deal 8 HP damage, the big ones deal 7, the medium ones deal 6, the small ones deal 4, the tiny bullets deal 2 and the explosion with a radius of 94px deals 3 HP damage.
 * Novae: 8 small fiery bullets appear on the track and then cause an explosion with a radius of 130px that deals 5 HP damage.
 * ☢ CAUTION! ☢ (Used when at 30% HP or lower): Heats up the track enough that every tower takes 1 HP damage every 2 seconds. Lasts until destroyed and cannot stack, can only be used once per A.T.O.M.I.C.. Also replaces all other abilities with these:
