Mantyke

Mantyke is a rather unique Pokemon in Little Cup. It is one of the few Water-types that can take on Grass-types thanks to its secondary Flying typing. This also makes it a good check to Fighting- and Ground-types. However, its Flying typing works as a double-edged sword as it gives it a crippling 4x Electric weakness and a weakness to Stealth Rock. Don't let this steer you away from using Mantyke, though, as it does have a few more things going for it. It has the best Special Defense in Little Cup by far and it possesses two great abilities, allowing it to be both a defensive and offensive threat.
