From threeA Wiki
Heavy Tomorrow Kings are a variant of the Tomorrow Kings characters that come with RPG's, Utility belts, Long Pants, and Backpacks. Released by ThreeA under the Popbot toy line.
Kato is the standard release and Nasu is the 3AA Exclusive release; both of these figures were released exclusively on Bambaland. Soh is a Retailer exclusive.
Disdained, outcast, ridiculed, mocked, called nancy boys and generally not invited to parties, Heavy TK's are the outcasts of an already outcast group, foregoing traditional weapons for big guns, they walk alone, masters of the boom.
