Semantics:
For those unfamiliar with the tier system, it ranks things on a 6 point scale, with the “S tier” being absolutely supreme, and with the “F tier” being absolutely dogwater. Right in the middle, there is the “B tier”, meaning “good”.
This means that if I prove that Dragonite is good, then I win the debate. However, if OPP proves that Dragonite is either better or worse than good, then OPP wins the debate.
To measure “good”, I will be using the metrics of gameplay and marketability.
The gameplay experience of dragonite is good, but not great:
In the games, Dragonite fills the role of a highly offensive physical attacker. Due to “dragon dance”, Dragonite can buff itself to sweep the opponent’s entire team. In generation one, Dragonite was one of the most competitive pokemon. But as the games kept evolving, power creep slowly pushed Dragonite out of the competitive spotlight. This all changed back in the eighth pokemon generation released in 2019, and now Dragonite is powerful once again.
This brings me to my first problem with Dragonite. Across generations, Dragonite has been inconsistent. Is Dragonite defensive, offensive, or even good? Does Dragonite have many high accuracy attacks? Can Dragonite use dragon dance? The answers to all of these questions have changed across generations.
The marketability of Dragonite is good, but not great:
Dragonite was the first dragon type pokemon, and so Gamefreak took extra time on its design. The design of dragonite was originally simplistic, with light oranges and round lines. This design emphasized that Dragonite was the good-guy dragon, in contrast to scarier dragons such as Rayquaza. Fans loved Dragonite, and throughout the Pokemon anime, Dragonite’s personality was fleshed out into a Dragonite of loyalty, friendship, selflessness, and honor.
However, Dragonite is poised in the awkward limbo between a scary dragon powerhouse, and a Snorlax-esque cuddly pokemon. People who like big scary pokemon don’t choose Dragonite, they choose Gyrados. And people who like cuddly pokemon don’t choose Dragonite, they choose Snorlax or Pikachu. Ultimately, Dragonite proved to be not much more than a template for more unique later pokemon.
That is embarrassing how I misspelled "tier" as "teir" in the very title of this debate.
