Blastoise

Blastoise is the final stage of evolution for Squirtle. Blastoise can be a brutal Pokemon with pressurized water jets on its shell. These water jets are used for high speed tackles. Although an actual Blastoise has not yet appeared in the television series, a giant robot Blastoise shows up to cause trouble as our heroes and Team Rocket get marooned on an island of giant robotic creatures.

First appearance: Episode 17—"Island of the Giant Pokemon"
