Dodrio opens its beaks and positions its heads so that each beak becomes a corner in the shape of a triangle. An orb of energy then forms inside Dodrio's beaks, the right one colored green, the top one indigo and the left one red. A red triangle then forms in between the orbs. Once the triangle starts to turn indigo, Dodrio fires the triangle at the opponent.
The three screws on Magneton's body glow white, and the white energy connects, forming a triangle. Magneton then shoots the white triangle at the opponent.
Hydreigon opens the mouths on its three heads and charges an orb of energy before each of them, all with different colors. It then fires an Ice-type move from the left arm head, a Fire-type move from the middle head, and an Electric-type move from the right arm head at the opponent.
Alolan Dugtrio spins around, sometimes rapidly, then a ball of yellow electric energy, light blue ice energy, and orange fire energy form around Alolan Dugtrio. Each of the heads then fires an electric, ice, and fire attack, from each ball respectively at the opponent.
Doduo opens both of its beaks and releases multiple pyramid-shaped energy from them at the opponent. When the energy makes contact, it explodes in a large burst of energy.
A three-point pyramid forms around Porygon's body and an orb of light forms at the tip of the pyramid. Porygon then fires a beam from the orb at the opponent.
