I still remember the first time I cracked open Pokémon Sun back in 2016. The hype was unreal. Game Freak was finally ditching the rigid Gym structure for Island Trials, and the Alola region felt like a genuine vacation from the repetitive pixelated grinds of earlier generations. But then, I met my Pokédex. Or rather, I met the ghost living inside it.
The pokedex for pokemon sun isn’t just a digital encyclopedia; it’s a living, breathing, and occasionally very annoying character named Rotom. It was a massive departure. For decades, the Pokédex was a silent tool, a sleek piece of tech that sat in your pocket until you needed to check a base stat or a habitat. In Alola, it became a chatty companion that took up the entire bottom screen of the Nintendo 3DS. Some people loved the personality. Others? They just wanted the map to stop talking so they could find their way to Route 8.
The Rotom Revolution: More Than Just a List
When we talk about the pokedex for pokemon sun, we have to talk about the hardware shift. This was the first time the Dex felt like it was trying to be your best friend. It would crack jokes, give you gameplay tips, and—most importantly—provide the "Rotom Rally" and "Roto Loto" features that gave you temporary boosts.
It’s weirdly nostalgic now.
Think about the technical constraints of the 3DS. Game Freak wanted to make the world feel immersive, so they moved the UI elements to the bottom screen to keep the top screen clean. The Rotom Dex was the solution. It gave you a real-time map, which was a godsend because Alola’s terrain is surprisingly vertical. You weren't just looking at a flat grid anymore; you were seeing 3D icons of where you actually stood in Hau'oli City.
But here’s the thing that gets overlooked: the Alolan Pokédex was the first to really lean into "Regional Forms." Seeing a familiar Exeggutor with a neck that reached the clouds or a Grimer that looked like a melted disco ball changed how we viewed the Dex. It wasn't just a checklist of 802 monsters (at the time); it was a field guide to biological adaptation.

That Brutal Difficulty Spike and the Dex’s Role
A lot of players complain that modern Pokémon games are too easy. They clearly didn't try to complete the pokedex for pokemon sun without a guide. Alola introduced SOS Battles.
If you wanted to catch a Mareanie, you couldn't just find one in the grass. No, you had to find a Corsola, get it to low health, and wait for it to "call for help." Only then would a Mareanie potentially show up—not to help the Corsola, but to eat it. That’s dark for a kid's game. This mechanic turned the Pokédex hunt into a war of attrition. You needed specific "Adrenaline Orb" items and Pokémon with the "False Swipe" move just to fill a single entry.
It was tedious. It was frustrating. Honestly, it was brilliant.
The Dex entries themselves took a turn for the macabre in this generation, too. If you go back and read the descriptions for Mega Evolutions in the Sun Dex, they’re horrifying. Glalie’s jaw breaks from the power of Mega Evolution. Salamence becomes a "blood-soaked crescent" that attacks its own trainer. The pokedex for pokemon sun didn’t hold back. It painted a picture of a world where Pokémon isn't just about friendship; it’s about powerful, dangerous creatures that are barely under our control.
Navigating the Alola Dex Structure
The Alola Pokédex is actually four smaller books inside one big one. You have the Melemele, Akala, Ula'ula, and Poni island sections.

- Melemele Island starts you off with 120 entries. It’s the "tutorial" island, but it houses heavy hitters like Salamence if you know how to trigger those rare SOS calls on Route 3.
- Akala jumps the stakes. This is where the variety really hits. You're dealing with the Lush Jungle and Wela Volcano Park.
- Ula'ula is the rugged, mountainous terrain. It feels massive compared to the others.
- Poni Island is the end-game. It’s wild, sparsely populated, and contains the highest-level encounters.
Completing an island's specific Dex gave you a sense of progression that the National Dex never quite captured. You felt like a local expert on that specific chunk of land. When you finally saw that "100%" stamp on the Akala section, it felt like a badge of honor.
What Most People Get Wrong About the National Dex
There is a common misconception that Pokémon Sun has a National Pokédex built-in. It doesn’t.
This was a huge controversy at launch. Players were used to finishing the regional story and then unlocking a massive list of every Pokémon in existence. In Sun, that didn't happen. You could transfer your old favorites from Pokémon Bank, but they wouldn't have a numbered entry in the game. They just existed in a sort of digital limbo.
Was it a bad move?
From a competitive standpoint, it didn't change much. But for the collectors, it felt like a betrayal. However, looking back with 2026 eyes, this was the precursor to "Dexit" in Sword and Shield. Game Freak was already testing the waters to see if they could move away from a "catch 'em all" philosophy toward a "catch what’s here" focus. The pokedex for pokemon sun was the turning point for the entire franchise's philosophy on data management.

Real Tips for the Modern Completionist
If you’re dusting off your 3DS to finish the pokedex for pokemon sun today, you need a strategy. The GTS (Global Trade Station) is... well, it’s a bit of a mess these days due to hacked mons and lag.
- Focus on the QR Scanner. You can scan 10 QR codes a day to trigger an "Island Scan." This is the only way to get non-Alolan starters like Chikorita or Cyndaquil in the wild.
- The 1% Encounters. Pokémon like Dhelmise have a 1% spawn rate in specific fishing spots (specifically the Steelix-shaped boat in Seafolk Village). Don't just fish anywhere; look for the bubbling water. If it’s not bubbling, exit the map and come back.
- Version Exclusives. You aren't getting Vulpix or Passimian in Moon. You aren't getting Sandshrew or Oranguru in Sun. If you don't have a friend to trade with, you're going to need a second 3DS or a lot of patience on the remaining trade forums.
The Enduring Legacy of the Alola Dex
The pokedex for pokemon sun changed the UI of Pokémon forever. It proved that the Dex could be a character, even if that character sometimes told you that your batteries were low when you were in the middle of a legendary encounter. It gave us the most detailed lore the series had seen in years.
It’s easy to look back and complain about the hand-holding or the constant blinking map. But Alola felt alive. The Pokédex reflected that. It wasn't a sterile list; it was a companion that reacted to your progress.
To actually finish the Alola Dex, you should start by catching a Smeargle on Route 2. Teach it False Swipe, Soak (to hit Ghost-types), and a recovery move. This "Catcher Smeargle" is your single most important tool. Without it, the SOS hunt will break you. Once you have your Smeargle ready, head to the shivering grass patches or the bubbling fishing spots. The Shiny Charm—the ultimate reward for a full Dex—is worth the grind, especially if you plan on hunting those Alolan forms that still look better than almost anything else in the modern Pokédex.
