Malamar’s brain has become enlarged as a result of Mega Evolution. Greatly enhanced psychic power overflows from its body, emitting a bright glow. This vividly coloured light further amplifies the Pokémon’s hypnotic abilities, allowing it to freely overwrite the personalities or even memories of others—a terrifying power that can make someone seem like an entirely different person.

Its glowing, undulating tendrils are able to pick up on the feelings of those around it. It prefers battling with efficiency, using its powerful intellect to analyse the situation with levelheadedness as it fights. Mega Malamar views others—even Pokémon Trainers—as its pawns. If it disagrees with an order given to it by a Trainer, it will sometimes respond by hypnotising them, making this an incredibly difficult Pokémon to interact with.
