Ability₈₉-Gulp Missile

If a Cramorant with Gulp Missile uses Surf or Dive, it catches prey and changes its form depending on its remaining HP.
🐟If its HP is over half, it catches an Arrokuda and changes into its Gulping Form.
⚡If its HP is under half, it instead catches a Pikachu and changes into its Gorging Form.
⚠️If hit by an attack in either form, Cramorant spits out its catch at the attacker, dealing damage equal to ¼ of the attacker's max HP and inflicting a secondary effect depending on its catch:
⚠️Arrokuda lowers the attacker's Defense by one stage, while Pikachu paralyzes them.
⚠️Cramorant returns to its base form after spitting out its catch.
⚠️If the attacker has Magic Guard, it will take no damage, but still trigger the cutscene and take the Defense drop or Paralysis.
⚠️If Cramorant Dynamaxes while it has a catch in its mouth, it reverts to its base form (without spitting its catch).
⚠️Even if a Dynamaxed Cramorant uses Surf or Dive (only possible as a wild Pokémon in a Max Raid Battle), it will not change into its Gulping or Gorging Form.
⚠️Gastro Acid, Worry Seed, and Simple Beam fail if the target has Gulp Missile.
⚠️Role Play, Entrainment, and Doodle fail if either Pokémon has Gulp Missile.
⚠️Gulp Missile cannot be copied by Trace.
⚠️Gulp Missile cannot be suppressed by Neutralizing Gas.
