Skurge the Executioner - insane that we don't have him yet. In a way, it's great that he could be released now, when Hasbro is kind of at its best. But a good release of Skurge would necessitate an update to Amora.
Gladiator (Melvin Potter) - I thought he was right around the corner after Whirlwind came out with those arm blades.
Colleen Wing - like Executioner, a good release of Colleen Wing would necessitate an update to Misty Knight.
Hepzibah (Starjammers) - They were on a roll with Corsair and Ch'od (and Binary). Finish the team with Hepzibah and Raza.
Skin (Generation X) - Maybe a little tougher to achieve than Synch, but not as tough as Penance or Mondo. Use those stretched Reed Richards hands and bare feet from Legion. Keep him skinny like Pizza Spidey, but maybe use the Amazing Fantasy body?
Wonder Man (WCA) - The sleeveless Wonder Man from Abomination wave doesn't count as a '90s Simon.
Yellowjacket - I've made so many customs of this guy that I'd love to replace with an official figure. Vulcan body please.
Ares (Dark Avengers) - He needs a redo.
Ronin (New Avengers) - They need a redo.
Echo (New Avengers) - Great design. Go with initial appearances with the hand print face paint.
BAF M'Baku - Call him M'Baku.
HasLab/oversize Mangog - I can't think of many other big characters I want or need. Growing characters don't really need to be HasLab big.
Maximum Iceman - modular ice slides, please.
Box Set Outback X-Men Colossus, Psylocke, Gateway - Topless Colossus, armored Psylocke, pot-belly Gateway.
