While all you nerds are geeking out about the map and the box art legends I noticed something that I am surprised that no one is talking about... Kukui!
In each game the first character you meet is the professor. They introduce themselves and tell you what scientific Pokemon field they study. The games tend to revolve around or highly emphasize a new mechanic based on what they are studying.
Professor Oak was studying Pokemon and human relations with them, which makes sense for RBY. It is the first game in the series and Pokemon was something new to all of us.
Professor Elm studied Evolution and Breeding. Gen 2 introduced breeding, baby Pokemon, and new lines of evolutions for most of the Gen 1 mons.
Professor Birch studied Pokemon habitats. RSE introduced a new way to catch Pokemon being the dive mechanic. There was also emphasis in the Box Art Legends and the evil teams wanting to create a new habitat for Pokemon by expanding the seas or expanding the land.
Professor Rowan studied evolution, like Elm in GSC. And like in GSC, a lot of gen 1 and 2 mons were given new evolutions.
Professor Juniper studied Pokemon origins. Even though there was a heavier emphasis in DPP on Pokemon origins, gen 5 approached the game story wise in a lot of a deeper way than the rest of the series up to date did.
Professor Sycamore studied Evolution. Do I really hafta say it? This one is obvious, XY introduced mega evolution.
Now we have Kukui and a new character named Lili. What is interesting is they have opposite personalities. Lili's character description mentions how she is not a fan of violence and Pokemon battling. Kukui on the other hand seems to love battling and the nature of Pokemon battling. Professor Halla is a retired samurai and Kukui is... Shirtless? My first thought when I saw that is "this man will spawn more fan art than Sycamore." However, after seeing his character description, something made him my current favorite professor. What if, like Halla, Kukui has a passion as a fighter. Lack of shirt may emphasize his love for the fight and how he is always ready for a brawl. Hence why he wears comfy shorts and lazily throws on his lab coat.
Even though this is all theory crafting on my part, let's actually look at his character description. It mentions how he studies Pokemon moves, aka attacks and fighting styles. His description even details how Kukui likes to learn more about Pokemon hands on by letting them attack him and learning what their attacks are like by experiencing them hands on. I get the feeling that this guy has a vendetta against nature and likes to go around picking fights with Pokemon for hell of it, which makes him the coolest professor to date. At least to me anyways
Getting to the point, Kukui studies Pokemon attacks. Does that mean something new or potentially big may be introduced in battle regarding our attacks and abilities? Will a pokemon's signature move change depending on certain battle criteria? Will Mega Evolutions change something about a pokemon's attack? I have no idea, but it is something that has been circling around my head. What do you nerds think? Is there a base for this theory, or am I just full of my own crap?
