Pokémon Diamond: The Final Fight - Weakness means nothing!

This is my last battle in Pokémon Diamond, between Legendary Pokémon Heatran and my favorite Glaceon, who defeated Boss Cyrus and Champion Cynthia. Glacia has weakness to all Heatran’s attacks, but even Legendary Pokémon cannot oppose for our power! Rare Candies and Full Restore in my hands makes my Glaceon invincible! Death to all who oppose us! Mwa-ha-ha-ha-ha!!! *much pathos*
