I got some of my own Egg Fighters.As a bit of an inside joke, the three Egg Fighter citizens are named after abbreviations of three key game consoles (the Mega Drive (Genesis in the US), Dreamcast, and Xbox 360) and the years in which their first Sonic games were released:
EF-MD1991 - Mega Drive - 1991, release of Sonic 1
EF-DC1998 - Dreamcast - 1998, release of Sonic Adventure in Japan
EF-XB2006 - Xbox 360 - 2006, release of Sonic the Hedgehog (2006)
EF-PS2008 - PlayStation 2 - 2008, release of Sonic Unleashed
EF-DS2005 - DS - 2005, release of Sonic Rush
EF-CD1993 - Mega CD - 1993, release of Sonic CD
You get the idea. You can make your own Egg Fighter in the comments and use the rules.
