It's hard to say which one is better: Floatzel or Gyarados. On the one hand, Floatzel is a fast-moving Water-type Pokémon with a powerful attack and agile swimming capabilities. On the other hand, Gyarados is a dragon-like Flying and Water-type Pokémon with high HP and Defense stats that make it incredibly resilient. Ultimately, it depends on the specific strategies you have in mind when deciding which one is right for you.
Floatzel is a sleek Water-type Pokémon, known for its exceptional agility and speed in water. Its Attack stat is one of the highest of all Water-types and it has access to a wide range of moves that make it a threat in battle. Its unique swimming style has earned it the nickname “Tsunami Pokémon”.
On the other hand, Gyarados is a massive Flying/Water type with very high HP and Defense stats that make it incredibly resilient against physical attacks. It can also make use of some powerful Flying-type moves like Fly and Air Slash to take down opponents from the sky. It’s one weakness is its low Special Defense stat, which makes it vulnerable to Fire, Electric, and Ice attacks.
