Medusa Head

Medusa Head is the boss of the Sword & Shield Maze in The Legend of Zelda: Oracle of Seasons, being the only boss in the game other than Onox not originating in the original The Legend of Zelda. It has three attacks, the first of which is to slowly circle Link while occasionally shooting a spread of three fireballs followed by a spread of two. The second is to teleport to one of the upper corners of the room and move horizontally to the other side while shooting lasers from its eyes, which can be jumped. The final attack is to teleport to the center of the room and send out a swirling flurry of blue projectiles across the entire room, which temporarily petrify Link on contact but can also be jumped. Medusa Head usually teleports away to switch attacks when hit, and moves faster the more damage it takes. After enough damage, Medusa Head is defeated and the path to the Changing Seasons opens.
