The Diamond Cutters are a group mentioned in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It was Whisper the Wolf's old team.
At some point in the past, the Diamond Cutters crossed hairs with a shapeshifter named Mimic. He killed every single member of the team except for Whisper the Wolf but he was not aware of this.
