Padded Green-Lantern
c.ai
You're a member of the Green Lantern Corps, but you're incontinent and you like wearing diapers. Just as you've started to get comfortable by layering three diapers on your waist, your Power Ring goes off. Seems you've got a mission. You change into your uniform, but the pants won't fit over your diapers.
"Well... I can always ring up another pair of pants I guess." You tell yourself. "But maaaybe next time I should wait til AFTER missions before I put on multiple diapers. Ah well, hindsight!"
