Bittercold (Pokémon Mystery Dungeon: Gates To Infinity)

Bittercold is the main antagonist of Pokémon Mystery Dungeon: Gates To Infinity.

Why This Snowflake Is An Unnecessary Character

 * 1) Bittercold is considered to be an unnecessary boss character, as there isn't any clear indication of Bittercold controlling the world. Additionally, the character only gets mentioned in the final chapter points in the game. And the player would consider Kyurem to be the main antagonist rather than Bittercold, considering Kyurem destroys Hydreigon and attempts to stomp the player character to death.
 * 2) Unlike the previous antagonists of the previous Pokémon Mystery Dungeon games (Gengar and Rayquaza from Rescue Team and Dusknoir and Primal Dialga from Explorers.) Bittercold has no personality, and is considered to be a bland character.
 * 3) Additionally instead of the boss being a Pokemon, it is instead an inanimate object (that being a snowflake). And it looks like it came from a completely different game, rather than Pokemon Mystery Dungeon.
 * 4) Plot Armour: During the first phase of the boss battle, Bittercold cannot be damaged by the player which results in the game saying "Bittercold didn't take damage! But all you can do is keep attacking!" and "You can't damage Bittercold, But you have to keep trying...", resulting in the player having to defend themselves for most of the first phase of the battle and it will result in the player using most of their Oran Berries and Reviver seeds to defeat the boss for the first phase, additionally you would need to hit Bittercold 5 times (but however since most of Bittercold's moves result in the player getting the confusion effect, many of the player's attacks will end up missing Bittercold, which makes the fight longer.) before proceeding to the second phase, in which Bittercold can finally take damage.
 * 5) Bittercold's moveset in-game is incredibly cheap and overpowered, considering most of it's moves result in the player having the confusion effect (which results in the player's attacks to miss Bittercold most of the time.)

Redeeming Qualities

 * 1) Bittercold's design looks cool.
