the directory were you saved you game. there is a folder with the name battlers.just make sure you copy/paster a dragonfly battler there. Or import via resource extractor/import via the engine, near scripts/database, as zylos said before. Well, about the dragonfly fight, just make sure you add a new enemy, with the dragonfly battler, and then, go to enemy groups, and make a group with a dragonfly, so you can create a battle with the battle command, with the dragonfly.
