Jimmy Jupiter is a child who has the ability to travel to...well, I'll let the redoubtable Ronald Byrd say it for me:
Little Nemoish fantasy-lands inhabited by intelligent insects, talking clocks, fairies, demons, and the like. His two friends from "the Land of Nowhere" were the dragon Wump-Jump and Ruffy Rabbit, both of whom materialized in the "real world" in one story.Jimmy is from the real world and is based here, and when a group of bullies picks on a new kid Jimmy comes to the new kid's aid. The people of Fairyland, in one issue, note that "in each generation there is one who can visit" their world, which explains, I guess, Jimmy's power.
