Mantyke

Mantyke is a unique Pokemon, as it is an amazing special wall that also has an offensive presence. It resists a good amount of types and has a very crucial immunity to Ground, giving it nice synergy with a decent number of Pokemon. To couple with Mantyke's defensive aspects, it boasts two nice offensive STAB moves in Hydro Pump and Air Slash, which can threaten many common threats in the tier. While it doesn't have the best abilities, both of them allow for Mantyke to play its various roles much more efficiently. The biggest downside to Mantyke is its crippling Electric-type weakness, despite its amazing Special Defense. It is also weak to Stealth Rock and has lackluster HP and Defense stats, though those are easily overshadowed by Mantyke's prowess as a special wall.
