Re: Iron Man suits you'd like to forget.
The nose- Just stupid. "It was supposed to strike fear and terror in the hearts of his enemies" I always picture Hawkeye laughing his ass off after hearing this.
The JRJR design with the moon boots-Ruined a great design. The slim boots and gauntlets on Classic II looked great; these looked like he was wearing oil barrels on his feet and Hi-C cans on his arms.
Heroes reborn- My 12 year old cousin back in the day once remarked "He looks like he has hockey sticks on his back" regarding the boot jet exhausts. What would a guy in a high-tech super powered suit of armor need with belts and pouches anyway.
