Blastoise (カメックス, Kamex) is a fictional creature in the Pokémon media franchise.
Blastoise is a Water-type Pokémon introduced in Generation I. It is listed as #009 in the Pokédex and known as the "Shellfish Pokémon". Blastoise evolves from Wartortle at level 36, which in turn evolves from Squirtle at level 16. As of Generation VI, it is also capable of undergoing Mega Evolution.
As a Poké Ball Pokémon
Blastoise makes its first appearance as a Poké Ball Pokémon in Super Smash Bros. Blastoise uses Hydro Pump as its attack. It stations itself on the stage and starts firing blasts of water from the cannons on its back. Any character that makes contact with the blasts of water will take moderate damage. The character will also be pushed towards one side of the screen. Characters that are on the other side of Blastoise will not be affected unless that person makes contact with Blastoise itself, which will then cause him or her to take moderate to high damage. Blastoise also moves back slightly for each blast of water and can fall off the stage if close enough to the ledge.
As a Poké Ball Pokémon
Blastoise reappears as a Poké Ball Pokémon in Super Smash Bros. Melee. Like in SSB, it uses Hydro Pump as its attack. Oddly, CPU-controlled Fox and Falco will try to reflect Hydro Pump in spite of it being immune to reflection-based hitboxes. Other CPU-controlled characters will try to counter the attack with their shields as well. Additionally, it fires faster than in SSB and does not push itself back as far.
Blastoise appears as a collectible trophy, unlocked as one of the 100+ trophies that can be collected randomly during normal play, such as in the Trophy Lottery and throughout the various Single-player Regular Matches.
According to an interview with Masahiro Sakurai, Blastoise was briefly considered as a possible playable character before it was switched out for Squirtle, because he thought having balance with the sizes and stages of evolution would be interesting.
In Super Smash Bros. Ultimate
Blastoise retains its role as a background character in the Kalos Pokémon League's Flood Chamber.
It also appears as a Spirit.
