As a fan of final bosses I'm thrilled to see what it will be for this one. Hopefully not a Dragon-type, so far they've been:
- Charizard (for me, but it's actually the starter of the type that beats yours) - Red/Blue - Jolteon (or Vaporeon or Flareon if Blue beats you) - Yellow - A lv. 51 Dragonite that knew Fire Blast - Gold/Silver/Crystal - Metagross - Ruby/Sapphire - Milotic - Emerald - Garchomp - Diamond/Pearl - Hydreigon - Black/White - Haxorus - Black 2/White 2
I'm thinking of a Ghost or a Grass type or maybe an Ice/Electric type. What do you want the champion/antagonist to use as his or her strongest pokémon?
