Back in 1986, Dragon Magazine number 111 printed an article by George MacDonald called "Quantum, Power and Super-Power in the Champions Game." This article detailed the subject of making a character at different levels of "power" for your Champions game.
As an example George created a character named Quantum (no relation to the mutant hero in the BBB). Quantum is a woman who gained super powers thanks to an accident with a device created by Doctor Destroyer (read the article for details). George presented tables of Quantum's stats. She ranged in five levels from a starter heroine, to a goddess of destruction who took on alien battle fleets.
Presented here are full write ups for all five versions of Quantum, based on George's tables, in easy to use character sheets, updated to 4th edition rules.
