Exclusive to Wave Two was a Clark Kent figure. This was apparently to be released on a card in the fourth wave, but as that wave was never produced it was only available for 5 proof of purchase seals.
Clark Kent is dressed in a blue suit and has his trademark glasses.
During the first two waves of figures, mail-ins were common, with two promotions spanning both waves. Strangely, no mail-in offers were used as incentives for the third wave, either because of waning interest in the line, or Kenner already felt the line was established enough not to need any.
