Agrius

Agrius was the brother of Oreius whom together were called the 'Bear Twins'. They were the illigitemate spawn of a woman whom Aphrodite commanded must marry, though she herself chose not to and fled to Artemis. Aphrodite put a trance on the woman to love a bear and thusly she was cursed with monstrous children as well as hate from both gods. Both were described as being eight feet tall, wearing nothing but blue jeans, being covered in shag-carpeted thick brown fur, with claws for fingernails, feet like paws, snouts for noses, and all their teeth being pointed canines. Agrius was obviously the wiser (or at least more commanding) of the twins as he ordered his noticeably less intelligent brother to do various tasks including 'punishing himself' which entailed Oreius slamming his own head into an object or causing other bodily harm. During the time of Percy Jackson's second year at Camp Half Blood the bear twins had found work with Luke Castellan who had alligned himself with Kronos. They traveled with him as his 'assistants' as he called them and followed him around the Princess Andromeda. When Percy Jackson, Annabeth Chase, and Tyson arrived unexpectedly they first encountered these beasts and Luke told them their story. While it is said that the Bear Twins like half bloods for food it is unknown if they have ever eaten an unlucky demigod.
