I had lots of fun with the new D&D Gamma World last night, just creating random mutant characters. Today I found a Gamma World online character generator.
Give it a try. Those characters rock!
For even more options (20 additional origins from Famine in Far-Go and 8 from Legion of Gold) check out the official Gamma World Random Character generator on the Wizards of the Coast website. They call it an Interactive Character Sheet.
And finally a third one: it does not seem to include Famine in Far-Go, but has the Origin Powers listed. That was missing from the other two character generators: Gamma World Random Characters with Power Cards.
I printed loads of random Interactive Character Sheet characters and keep them in my Gamma World box. If a player needs a new character, he or she just pulls out one of them and decides if he wants to keep it. (I also photocopied all the origins, so that players don't have to look up their powers in the rule books during the game.)
