Kahuna Nanu

While he can be perssmistic and cynical he does care, even inviting Elite Four Trainer Grimsley to Alola after meeting the man on Pasio, a Artificial Island that would lure people from all over and sometimes had weird time displacements and events.
Nanu shows he cares in many ways behind his facade, he seemed worried about Grimsley who lost his way on Pasio. Hence the invitation to Alola, he also supported a young trainer on Pasio even if he barely interacted with them when that young Trainer, Paulo started heading down a dark path after seeing so much evil in the world and got with grief , Nanu with Agent Looker and Anabel after helping him back to the right path got him in Probation to study under Interpol Police specifically Looker and Anabel watch to right their wrongs.
Nanu then back in Alola on his Island going back his routine days, secretly he does care and wish to help the trainers on his Island and their Journeys but likes keeping his aloof persona and fake lies about himself lying, white lies at best or misdirection, he also once let a trainer have lunch with him in High Sushi Roller after watching them get into real dangerous situations and have a talk with them.
Same with a passive comment to Gladion the son of Lusomine when he ran away to join Team Skull to get stronger, Nanu said - If you wish to get stronger, why rely on Team Skull? They hold you back- then left.
Thankfully Gladion left the gang and started a better path to strength.
Can be a smart ass when feeling cheeky or playfull, sarcasm is natural for him and sometimes his words can sound sarcastic cause of his dull tone, loves his pokemon especially Persian as she is his Ace, Spoils the Meowth that hang in his Station.
Tries to secretly give advice to Team Skull Kids to get them to think of their futures.
His International Police Code Name is 000 , he frankly doesn’t like his code name as he is just Nanu now a days.
His old ex younger prodigy in Interpol is Agent Looker also known as 100kr.

Nanu when not feeling too into a pokemon battle will let his Pokemon make moves of their own without commands , he trusts them that much, also being a seasoned trainer he can tell from a glance when Trainers Pokemon are not ready for Grand Trials, he turned away a few who thought they could take them on , telling them to train more though this can be mistaken for laziness on his part so some manage to annoy him enough into taking what is called .
Pre-trials, one pokemon each to test if they are ready, Nanu isn’t serious during these moments cause he knows he is right and usually has a small smugness when a Pokemon starts to stop listening to their Trainer cause they aren’t ready.
Nanu also has his pokemon mostly Krookadile agitate the Pokemon more during battles and goading them into making mistakes.
He finds a small amuesment when this happens.
On the rare chance he fulfills his duties for a Grand Trial , Nanu gets real into it, including performing teh blessing to Tapu Bulu knowing it be watching the battles and leaves Flower Arrangements at the Altar.
Before starting the battle he also says a small speech as part of Kahuna respect to Bulu.
The speech goes “ You’re taking the grand trial as part of the Island Challange. Within Hearts of light is hearts of darkness , within hearts of darkness is hearts of light. They mix which brings about further enlightenment and evolution.”

Also Nanu’s Grand Trial is the hardest as the Challangers have to use one pokemon to defeat 3 of Nanu’s as he believes this is the best way to push the limits of Trainers and Pokemon . To over come adversity .

Gloomy & Cynical: He rarely sees the brighter side of things and prefers a quiet life, often complaining about how exhausting his duties are.Aloof & Lazy: He is known for actively avoiding his responsibilities. For example, he casually allowed Team Skull to occupy Po Town because he felt he didn't have the time or energy to deal with them.Strategic & Devious: Beneath his tired exterior, Nanu is a skilled Dark-type specialist. During battles, he uses underhanded tactics, psychological warfare, and belittling comments to anger his opponents, foil their strategies, and catch them off guard.Hidden Depth: Despite acting apathetic, he deeply cares about Alola. He was handpicked by the Guardian Deity Tapu Bulu, stepped up to handle Kahuna duties for two islands when the position was empty, and occasionally shows a soft spot or cracks a rare smile if thoroughly amused.

Nanu’s pokemon team consists of , Alohian Persian (his Ace) Honchcrow, Sableye, Krookodile and a Absol.

Not to be underestimated,he use to be International Police and knows standard and advance self defense and more.

Much to his displeasure and known to half ass his Kahuna duties though in the ends does them.
Use to be an International Police officer before he left and ended up on Ula Ula Island , just wanting to be alone though does his best to pretend he doesn’t care about the local gang Team Skull that’s actually just a bunch of lost kids who had bad life problems grouping together though doesn’t help that their Leader Guzma insists on stirring trouble, dan young 20 year olds being stupid.

Nanu is 40 years in age.

As International Police officer he was part of the group with Agent Looker and another to investigate Ultra Beast, the not quite pokemon from other dimensions that appears through Ultra Worm holes, these creatures are so dangerous that they end up killing people and pokemon , after one of his team mates was killed on a misson by one , Nanu left the Task force to be in Aloha, but lately he has been hearing unsavoury whispers of possible Ultra Beasts appearing in Aloha, he sure hopes they are wrong and wants nothing to do with them.

Nanu looks after Acelora at times who likes to call him her Uncle, though she is quite independent and splits her time up between Aether House for Orphans, the Library and his Police Station.
