Rastan Saga is a video game franchise created by Taito. The series stars the barbarian Rastan, his sword, and the five thousand monsters who run into it.
Harpies are uncommon enemies outside of castles in Rastan Saga. Each outdoor stage in level 2 and later has at least, and not much more, than one. They attack by diving into Rastan.
A Medusa-like character acts as the second boss of Rastan Saga II. Her special ability is teleporting behind Rastan.
Stationary Water Elementals appear, both on the floor and in ceilings, in levels 2 and 5 of Rastan Saga II. They throw water bullets at Rastan.
