Technical Breakdown
Greninja’s susceptibility to Psychic- and Ground-type attacks is attributable to its Dark- and Water-typing. These types grant it resistances to Ghost, Dark, and Water-type moves, but also confer weaknesses to Psychic and Ground-type abilities. The former exploit Greninja’s susceptibility to mental attacks, while the latter leverage its vulnerability to earth-based powers.
Performance Insights
Greninja’s performance is significantly impacted by its susceptibility to both Psychic- and Ground-type attacks. Against Psychic-type opponents, its Water-type weakness renders it vulnerable to powerful Psychic moves like Psychic and Psyshock. Similarly, its Ground-type weakness makes it susceptible to Ground moves like Earthquake and Drill Run, which can deal significant damage. As a result, Greninja requires careful positioning and support to mitigate these weaknesses and maximize its effectiveness in battle.
