Try a themed group. "The Frat Boys." "The French Philosophers." "The Special Olympians." Then, have the press lionize them above your PCs. It'll drive them nuts. ;-)
Mixing and matchiing is probably easiest.
Example: The Rough Mechanicals
Brick: Zebediah "Boozer" Davis, 170 year old alchoholic ex-gold miner on a bender. Got drunk in 1852 and hasn't sobered up yet. Theme powers include "too drunk to feel pain" and "drunken rage."
Mentalist/Mystic: Ricky the Thinking Brain Dog (credit to Pratchett). Zebediah's 150 year old dog, happy, stupid for a human (IQ of 80), awesome mental powers. Mental Paralysis effect: Go Lick Yourself.
Martial Artist / Gadgeteer / Weapon's Master: Floyd "Barman" Hooker. Skinny potbellied 182 year old bartender alchamist, can turn anything found in a bar into a deadly weapon. Brewed the Eternal Red Eye that created the Rough Mechanicals. Shouldn't have mixed in those funny mushrooms from the meteor crater in the Indian burial grounds.
Patriot / Speedster: Vladislav "Red Ink" Kopernik. Came to America in 1864 as an accountant for a mining company and was drinking in the bar on Eternal Red Eye Day. Small, skinny, gloomy. Surfs on red ink that sprays from under his fingers, may also entangle or blind foes using same ink. Insanely law abiding, loves his country, fights evil because it's disorderly.
Power Armor / Metamorph: Frieda "Still Married" Dueseldorfer Hooker. 180 year old fat shrewish wife of Floyd, wears shape-changing power-armor made of "Drunken Metal" remains of Floyd's brewing equipment and things Floyd has added from various bars over the years. Some shape changing and regeneration powers of her own, all offense (other than personality based) comes from suit.
Background:
Ever since ERE Day, the Rough Mechanicals have worked together for Truth, Justice, and the American Way of Life. Well, technically, only Red Ink and maybe Ricky have cared about those things, but the others have tagged along. Low on offensive power, the absurd regenerative powers bestowed by the Eternal Red Eye together with over a century and a half of experience have made the group surprisingly formidable, and the accumulated wealth generated by Floyd's pattents (he invented the pub quiz) and Vladislav's investing accumen have made them rich. Floyd has yet to duplicate the ERE, but he swears that it's only a matter of time. Meanwhile, wherever evil rears it's ugly head, wherever good men suffer, wherever the taps break on game night, there you will hear the battle cries of the Rough Mechanicals!
Boozer: You think yer better than me!
Ricky: Woof! Woof!
Barman: Have one on the house!
Red Ink: Time to ballance your accounts lawbreaker!
Still Married: What would you mama think of what you doing!
