Maractus is a cactus-like Pokémon, with a pair of large ear-like extensions emerging from its head, reminiscent of cactus arms. These extensions feature dark green spiky arrangements at the base, yellow spikes midway up, and are topped with flowers composed of six pink petals and a yellow center. It has a yellow spike on its forehead, yellow eyes, and a spiky-looking mouth. It has two lobe-like arms resembling those of cacti, and its hands each feature three yellow spines serving as fingers. Other dark green spiky arrangements adorn its neck, wrists, and the base of its body where the green spikes are arranged in a five-pointed star.
