is the evolved form of Ash's Poipole
. It evolved offscreen in it's home world. After helping defeat the Guzzlord, it agreed to stay around to battle in the Alola League Exhibition Match against Professor Kukui
Alola League Exhibition Match
Kukui’s fifth Pokémon to battle in the Alola League Exhibition Match was Lucario. Ash's Naganadel
was the one tasked with matching up against Lucario. Wicke
commented that she never could imagined an Ultra Beast would bond with a Trainer and take part in a Pokémon battle. Naganadel’s X-Scissor missed completely and Lucario’s Close Combat caused real damage as a quick follow up.
Throughout the battle, Naganadel was very open to Ash’s guidance as he had been showing it the real meaning of friendship since it was Poipole and it was now battling on Ash’s behalf. Naganadel used Sludge Bomb but Ash forgot that Poison-type attacks are completely ineffective against Steel-type Pokémon. In terms of offense, defense, and speed, everything Professor Kukui's Lucario
did in the battle was in perfect balance but they made a critical mistake as Ash imitated Kukui in the way he battled. Since Lucario wouldn’t let them land any attacks like they normally do, they switched strategies with the circumstances and met head on with an X-Scissor which clashed with Close Combat but then Naganadel used Dragon Pulse very close and scored a big hit to knock out Lucario.
