Naganadel is a large
purple striped Pokémon that has both draconic and insectoid features. The top half of its body is slender with thin arms and fuchsia-tipped claws. Both shoulders have gray spikes. Naganadel possess
purple draconic wings, which it uses to
fly. These wings have a
single fuchsia claw at the joint and darker
purple membranes. At the end of its long
neck is its head, which has a large spiked crest and gray face spikes that act as mandibles when it opens its mouth. Its glowing cyan eyes are conjoined, giving the appearance of a visor. The lower half of its body is an abdomen that resembles a wasp's abdomen. There are three gray spikes on the end of the abdomen, with the middle one being the largest and resembling a hypodermic needle or a wasp's stinger. In the anime, Naganadel is shown to be able to communicate with
humans through telepathy and show them visions of the past.
Naganadel's main stinger can eject a powerful, adhesive, and luminescent poison at a distance of over six miles. The abdomen contains hundreds of liters of this poison, as well as the Ultra Beast's brain. The stingers on its abdomen are directly connected to its brain, and it
will react with violence if they are touched by anyone.1 Naganadel originates from Ultra Megalopolis in Ultra
Space.
