Rouge the Bat is a character in the Sonic the Hedgehog video game series, who is a determined treasure hunter and part-time government agent who plans to make all the gems and treasures of the world hers. Her main jewel obsessions are the Master Emerald and Chaos Emeralds. She made her debut in Sonic Adventure 2, released June 18, 2001, and has been featured in several games following it.
In Sonic Heroes and the two Sonic Riders games, she wears different outfits, but often with similar color schemes and heart-shaped details
Rouge has been confirmed to have been created by Sonic Team USA. Details of whether her final design was originally going to look as it does is unknown, although Rouge was originally going to be called Nails the Bat, the name Rouge was chosen over Nails because “rouge” refers to “Jeweller’s rouge”, displaying Rouge’s love for precious gems.
