All 119 enemies of Phantasy Star II you will encounter.

Unlike in Phantasy Star I, where only a single ememy type could confront you, in Phantasy Star II you often will run into different kind of monsters at one time. The amount of experience points and mesetas depend on the number of party members, the less members the group has the more money and experience points you will gain. On the other hand no information is given about the strength of the enemy (no hitpoints are displayed). So it is too difficult to create an exact list about the monsters, robots, and main enemies. Only the location of the monsters is displayed in this list. And they are all animated, of course.
