A Blood Beast is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a cheetah-like monster that Knuckles claimed to have originated in Mobian storybooks.
Knuckles encountered a pair of Blood Beasts as he ventured into Merlin Prower's dwelling on his quest to find the Sword of Acorns in order to heal the crystallizing King Acorn. The two creatures attacked him but were easily defeated.
It was later revealed that Merlin Prower had summoned the creatures to defend his dwelling as part of his powers as a charlatan.
- These creatures resemble Displacer Beasts from Dungeons And Dragons.
