1.
The Parasect attacks the Lapras with Fury Cutter, a bug-type fast move, and the Lapras makes a counterattack with Frost Breath. The ice-type fast move is super effective against the Parasect.
2.
Due to Fury Cutter's higher EPS (gained energy per second), the energy bar of the Prasect is charged quickly. The Parasect uses Solar Beam, which is super effective against the Lapras.
3.
The Parasect shoots Solar Beam again, then the Lapras counters with Ice Beam. The ice-type charge moves is dodged, but the Parasect is still damaged.
4.
The Lapras gets angry about the dodge and it uses Ice Beam again. Even though the Parasect tries to use Solar Beam, it is defeated before Solar Beam hits the Lapras.
