For me, it was:
1. Of course, Comrade Valmar Core, the Three-Faced... he really gave me a hard time! I only beat him on the 6th try!:(
2. Melphis. He completely wrecked me with his crown attack! I beat him on the 3rd try.
3. The Eye of Valmar. Well, naturally, him too! Quite cunning, and besides, he has gears in the form of small eyes (chocolate ones?:D) that help him... I beat him again on the third try.
