Inspired by the Battle Cry thread....
Pick an everyday concept, the LESS heroic the better (for comic effect). That will be the SUPERGROUP name, then riff a bunch of thematic member character names.
EXAMPLE:
SUPERGROUP: The Liquid Tide
Members:
Rin Psychle
Dry R. Sheetz
L'andre Baskette
The Agitator
The Soiled Avenger (probably a Stone/something tanker, or maybe his name would be Poostane, Earthenplop or Skid Marx)
Bo Rax
D. Tergent
...you get the idea. The example theme was laundry. You could pick cheese, fruits, states, countries, astrological signs, fast-food restaurants, vehicle, cartoons, tv shows, furniture, emotions or any other of the millions of familiar categorizations of concepts we take for granted every day and could use a stinging comical reminder of.
BONUS (for the more creative and sober among us, which temporarily excludes me): Combine TWO distinct concepts such as laundry and communism, which would for example match "Skid Marx" above.
OTHER BONUS: If possible, describe the character's archetype and any relevant power choices. Rin Psychle almost has to be a Storm defender, right?
