I asked for an assist with this incarnation of the DC 2099 contest by contacting the imaginative Comic Viner The Dark Huntress. She came up with a suggestion I think is great and relevant to DC.
BATGIRL. 2099. Barbara Gordon's incarnation as BATGIRL.
Deadline will be September 10th, 2011@ Midnight Central Standard Time USA.
Have fun and any medium accepted.
EDIT: To avoid any problems, please don't use Barbara's incarnation as Oracle, avoid using Cassandra Cain's Batgirl costume. Just Barbara Gordon as Batgirl, please. Again, please have fun!
