As the title suggests, a fair amount of the comic takes place in David's atomic powered laundromat. Where he is aided by his transforming robot (made from a washing machine of course). There's the love interest, who has no super powers (though she wants them very much) unless maybe you count super-lawyering. A powerful psychic who asks for a job at the laundromat. The duck that was part a bartered payment before David stopped accepting those.
Recent storylines include his younger sister's Sweet 16 birthday party (Who as a the child who is visibly showing alien heritage has been chosen as the heir to her mother's throne) and his father's facing a trial.
Oh. I gave two titles up there, didn't I? This comic is available in English as Atomic Laundromat and in Spanish as Super Lavandería.
Atomic Laundromat updating Monday, Wednesday, and Friday
Super Lavandería actualizado lunes, miercoles, y viernes
Which is handy for someone who's trying to learn Spanish on their own. :) (And it's released under a creative commons license that would even allow potentially sharing any graphical flashcards made from it so long as they were offered on the same terms and had proper attribution)
