A pagan knight whose brother, Sansfoy, was slain by the Red Cross Knight. He encountered Una, the Red Cross Knight’s amie, traveling with the evil magician Archimago, disguised as the Red Cross Knight. Seeking to avenge his brother’s death, Sansloy attacked Archimago and wounded him, but discovered his true identity when he lifted his helmet. Sansloy then killed the lion protecting Una and abducted her. He tried to rape her in a forest, but a group of satyrs responded to Una’s cries and drove him away.
