The ever-sensitive topic of racism in fan art reared its ugly head again last night when an artist decided she had to "fix" another artist's gijinka drawings of Sonic the Hedgehog, Tails and Knuckles as white children by making Knuckles black.

The original post was by @tsuki_s_0623, and shows the main Sonic trio as anime children.

Things went off the rails when Twitter user @mysticmaryy reposted the art but made Knuckles black, writing "Fixed ur shit for u." She was then blocked by the original artist, and proudly declared, "a story in two parts."

@tsuki_s_0623 expressed that they were upset the artist repainted their work without permission, not about the skin color alterations to their original piece.

The situation caused "Knuckles" to trend on Twitter this morning, as people mostly rolled their eyes at @MysticMarry's attempt to "fix" the original piece.

@MysticMarry later apologized for the incident.
