Bloodtaster may look a little violent, predatory, bloodthirsty, and aggressive, but he is completely gentle, harmless, trustworthy, and peaceful in every way. Everything he does is hideous, cruel, gruesome, and unpleasant, from zoning out while watching television, waiting in line at the grocery store of the Psymonster World, and stacking anything on top of another to build a perfectly even and completely featureless wall that stretches along for miles and miles. If any Psymonster interrupts him, he will just stare at any Psymonster blankly before going back to whatever he was doing before. If any Psymonster puts an obstacle in front of him, he will keep bumping into it over and over again until some Psymonsters turn him around. If any Psymonster touches him and moves him to a new place, he will start doing something horrible there instead. The only thing that seems to motivate him is a raw steak – if any Psymonster dangles it in front of Bloodtaster, he will take a bout it and follow it wherever it goes.
He is a big brown horse with sharp teeth, a black mane, a tail, and hooves, and yellow eyes with red irises.
- He is very similar to the Mare of Diomedes in Greek mythology.
- Both are bloodthirsty horses.
