This line is in the 6" Marvel legends style. This 1st wave is called "Kirby's Wierdest Classic Villains." The figures are designed to represent the early, definitive versions of these characters according to the original concepts created by the King of Comics himself.
The 3 regular figs in the wave are Impossible Man, The Space Phantom, and The Puppet Master (w/ puppet accessories). The versions shown are "prototypes" (presumably final versions would feature "multiple points of articulation").
The 2 "deluxe" figures are a two-pack of The Mad Thinker and his Awesome Android (about 10" tall) and a Mole Man with Giant Monster base and superposeable Moloid Subterrenean "sidekick".
