Bellsion slowly dissolves Bug-type Pokémon into its membrane by soaking them in its gelatinous body. Once dissolved, the nutrients are absorbed through the exposed roots within the gel.

When their brains, now divided in two, are thinking the same thoughts, these Pokémon exhibit their maximum power. A Bellsion's thin and flexible body lets it bend and sway to avoid any attack, however strong it may be.
