Exeggapex is protected by a durable substance similar to eggshell. It uses its serrated edges to slash at other Pokémon, both to hunt prey and to protect itself from being flipped over by predators to expose the vulnerable head within its shell.

Those attacked by Exeggapex's poison will suffer intense pain for three days and three nights. It consists of six eggs that care for each other.
