Giovanni & Mewtwo

With incredible base stats, two extremely useful typings, and strong self buffing, Mewtwo is one of the most versatile Strikers available. Its ability to take to the field, use “Nowhere to Hide” once or twice, and then start dealing damage without any further setup makes it extremely easy to use in Co-Op since it can fit on any team. In single player, where both max Critical Hit Chance and max Sp.Atk are preferable because opponents are bulkier and there is only one Move Gauge, Mewtwo can still be highly effective. However, it does require a support to raise its Sp.Atk to do this, keeping it out of the upper echelon of Strikers like Sceptile and Charizard who can get there themselves and then use both of their teammates for things like Defense buffs and Gauge regeneration.

Self-Sufficient In Co-Op 

Thanks to its monstrous Sp.Atk stat and “Nowhere to Hide!” allowing it to max out its Critical Hit Chance very quickly, Mewtwo is one of the few pairs to be able to switch in at any point in a Co-Op game and immediately start dealing damage. This makes it an incredibly versatile pair that can be used to great effect on any team against any boss. Additionally, it makes it very easy for the player to pivot out of Mewtwo into a Support if they are targeted by the Stage Boss, and then switch in again and resume dealing damage with little interruption. 

Dual Typing

Mewtwo’s ability to deal equally solid amounts of damage with Ghost and Psychic type moves adds quite a bit to its versatility and general usefulness. In both Co-op and the Battle Villa, dealing Supereffective damage is heavily emphasised, and being able to do that twice as often means Mewtwo will be the best Pair for the job twice as often. Not only does this make it a stronger Pair, it also makes it a better investment to Level Up and Boost since if you have a powerful Mewtwo, you won’t need another Psychic or Ghost type to deal Supereffective damage with. 

Requires Support For Optimal Damage 

While being able to deal damage with only its own Critical Hit Rate buffs makes Mewtwo incredibly versatile in Co-Op, it also means that it requires Support pairs to raise its Sp. Atk to reach optimal damage. This hurts its reliability in Battle Villa in comparison to pairs like Sceptile and Houndoom by forcing one or both of its team’s other slots to be used on a Support that can max out its Sp.Atk.

Mewtwo is versatile enough to fit on most teams in Co-Op, although pairs like Eevee who can pass on buffs will make it even more effective. In Single Player, Mewtwo should nearly always be used with a Support like Nosepass or Serperior who can raise its Sp.Atk and either boost its Speed or regenerate the team’s Move Gauge.
