Star Ocean: The Last Hope

In order to get this achievement, you must fight at least one of the 154 different types of monsters. Most bosses count.

You can keep track of which enemies you've fought in the collections section of the menu. For the achievement, you merely have to fight each type of enemy once. Do not worry about maxing the research out on them.

As you progress through the game, the collections section will keep track of the monsters you fight more or less in the order you fight them. If you're missing a spot, you most likely just missed out fighting one at some point.

There are some enemies you can miss on your playthrough:

- Fight the Lizard Soldier, Wise Lizardman, and Lizard Commander before completing the Celestial Ship on Lemuris
- Defeat the Guard Bot "Commando", Guard Bot "Assaulter", Cardianon Soldier, Lizard Warrior, Lizard Shaman, Armed Dragon Newt, Cardianon General, Armed Dragoon, and Dragon General before completing the Cardianon Mothership.

If you fight every monster as you come to them, you should get the achievement after defeating the Ethereal Queen, netting you a nice double achievement.

Finally, make note that the only Coliseum monster that appears on the list is Ashlay, the number 1 spot on the Team Battles in the Coliseum. Also, there's a chance you will fight him in the Endurance matches, which is the first time I encountered him.
