Midway through the two-day charity auction to name one of the main characters in Mark Millar and Frank Quitely's Jupiter's Children, the high bid is already $2,550 (the starting bid on Wednesday was $100). Proceeds again will go to the St. Bartholomew's Primary School Pantomime Fund to help send students to Christmas shows.

Millar previously auctioned the rights to name characters in Kick-Ass (Dave Lizewski), Nemesis (Matt Anderson and Blake Morrow), Supercrooks (Chris Matts) and The Secret Service (James Arnold), with proceeds going to such projects in his native Scotland as a playground for children with special needs and a specially equipped mini-bus. Last year's Secret Service auction also helped to raised funds to send children from his elementary school to the annual pantomimes.

"It's something I'd like to do every year and expand into other schemes in the community with a few other ideas I have,” Millar told The Hollywood Reporter. “Some of the kids had never been to the city before and when I went back to my old school to hand out prizes last summer they all told me how much they enjoyed it.”

Announced in January, Jupiter's Children centers on the offspring of superheroes who have essentially squandered their inheritance, failing to live of to the example set by their parents, who gained their powers in the 1920s after discovering a mysterious island. The 12-issue series is expected to debut in April from Image Comics.

By way of comparison, last year's winning bid to name the villain in The Secret Service was $5,100; the Nemesis auction in 2010 brought in $8,500. You can bid on eBay until Friday at 8 p.m. ET/5 p.m. PT.
