Slowbro

Slowbro is a huge defensive threat in the CAP Metagame. Mega Slowbro acts as a fantastic physical wall thanks to its huge 95 / 180 physical bulk. Slowbro can also be used as a bulky pivot before Mega Evolving thanks to its access to Regenerator. Mega Slowbro also has a good ability in Shell Armor, which prevents the foe from taking it down because of a lucky critical hit. Slowbro's base 130 Special Attack when Mega-Evolved and 100 in its base forme allow it to also net KOs against a great number of offensive Pokemon. Slowbro's typing is also great, as Water / Psychic gives it super effective STAB coverage on common Pokemon in the metagame such as Tomohawk, Talonflame, and Colossoil, as well as a plethora of resistances, particularly to common attacking types such as Fire and Fighting.

However, Slowbro's pitiful base 30 Speed means that it will go last against most of the metagame. Slowbro is also very vulnerable to users of the move Taunt, as they can completely shut down most Slowbro sets. Due to its reliance on Slack Off and its lack of status-healing moves outside of Rest, Slowbro is also very vulnerable to status ailments, especially Toxic poison. Its 90 / 80 special bulk is, while not bad per se, can be pretty disappointing. Finally, while Slowbro's typing does grant it a good set of resistances, it also gives it some nasty weaknesses to Electric, Dark, and Bug, which are pretty common types in the CAP metagame.
