The 6 inch Action Figures have some of the most unique features we ve introduced in an action figure. Playing up the DNA elements from the series DNA slime bubbles ooze out of the figures. In addition to the cool DNA feature each figure has an additional action function for increased play patterns. Heatblast features a flaming red light-up head and a chest cavity that is filled with oozing DNA bubbles. The punching action of the hulking Fourarms is rivaled by the DNA bubbles oozing from his massive chest! Diamondhead s features include a light-up head an arm that shoots missiles and an arm that is filled with glow in the dark slime.
