SEGA released a little collection (with bios) of other characters in the Sonic Boom universe, whether they inhabit the 3DS version, Wii U version, or are in the television show. And there's so little tape there, unlike the playable characters, which inspired a lot of tape-filled fan art.
"Perci is beautiful yet tough as nails; her street smarts and tough exterior allow her to be ready to protect the town when the time comes."
No sexy male possibly-also-a-hedgehog? Alienating half your audience there, guys.
