Palafin

Palafin leverages Zero to Hero by using Flip Turn early to transform into its Hero form, at which point its Attack stat becomes overwhelming. Adamant with 30 Attack SP maximizes Hero-form Jet Punch priority damage. White Herb offsets the Flip Turn defense drop so Palafin does not arrive in Hero form weakened. Drain Punch provides a self-sustaining option in longer games, and the HP investment keeps it healthy enough to absorb a priority hit before completing the hero transformation.
