Diamond Cutters

The Diamond Cutters are a group mentioned in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing.

Past
At some point in the past, the Diamond Cutters crossed hairs with Dr. Eggman and a shapeshifter named Mimic. Their attack on the Diamond Cutters costed almost all of the members their lives. Whisper the Wolf was the only member who survived the attack but this was not known to anyone else.
