A strong ability in Parental Bond synergizes well with Seismic Toss toboost Mega Kangaskhan’s damage to acceptable levels, as well asgranting it decent utility through amplifying secondary effects. FakeOut gives Mega Kangaskhan a niche as an anti-lead with the ability tobreak the Focus Sash of other dedicated leads such as Smeargle and hasstrong synergy with residual damage such as from Toxic Spikes. Despiteits decent defensive stats, Kangaskhan lacks useful resistancesoutside of its immunity to Ghost-type attacks. Due to this, it caneasily be broken through by the offensive titans of the metagame, suchas Primal Groudon and Marshadow, and cannot take on many threats byitself in a one-on-one scenario. Due to the naturally high HP stat ofmany threats in the tier, Mega Kangaskhan requires heavy support,typically from Toxic Spikes, to achieve crucial 2HKOs with SeismicToss and amplify Fake Out damage. This greatly restricts the types ofteams that Mega Kangaskhan can fit on.
