Re: HERO Hall of Fame?
My favorite was Gemini, whom I played in a Champs 3E game and hope to bring back as an NPC in The Campaign I Will Run Someday.
His power set was nothing earth shattering. Duplication (one dupe), some gadgets and ehnanced senses and martial arts. He was the team scout/stealth guy and computer expert. When he was one person, he could be invisible. When he was two people both could be intangible (Desolidification). The rest of the team called the dupes Gemini Red and Gemini Blue given his costume's color schtick.
The thing that made him a beauty to play was he did not consider himself to be two people, but had either Psychological or Physical Limitations (I forget which) about pronoun use. When he was one person, he refered to himself as 'we'. When he was two people, both of them refered to BOTH selves as me/I.
This drove players nuts at the table, especially when the separated Red and Blue would both be talking on the (audio only) team communicator. It culminated in a plot where one of them was away for months undercover, and in the meantime the other had been dating a woman and gotten engaged.
Role-playing both sides of the conversation that ensued upon the dupe's return I said:
"If I think I'm going to let me marry a woman I've never met, I've got another think coming!"
