Some challenge

Like other Pokémon games, Ruby‘s gameplay is linear; the main events occur in a fixed order. The protagonist of Pokémon Ruby is a child who has recently moved to a small town called Littleroot Town At the beginning of the games, the player chooses either Treecko, Torchic, or Mudkip to protect Professor Birch, the regional professor, from an attacking Poochyena. After defending Birch, the player is taken to his lab and receives the chosen Pokémon as their starter Pokémon. After that, the player encounters May/Brendan, the child of Professor Birch. The player’s rival, who appears as the professor’s child, is also a Pokémon Trainer and occasionally battles the player.

MISSION REPORT: POKEMON RUBY SWORD AND SHIELD RANDOMIZER

Explorer: DexHunter Ace (LVL. 100)
Expedition Duration: 12 hours, 47 minutes
Pokedex Completion: 31.2% (UNACCEPTABLE)

INITIAL ASSESSMENT

Okay. OKAY. Deep breaths. Let me explain what happened here because my hands are still shaking and it's not from the coffee this time.

I loaded into Littleroot expecting the standard Hoenn experience with some Gen 8 flavor splashed in. What I got was chaos incarnate. My starter selection? Wooloo, Applin, and Falinks. Professor Birch was being attacked by a WILD DRAGAPULT. In the tall grass. At level 5. The laws of nature have been suspended in this region.

THE RANDOMIZER PHENOMENON

This region operates on what I can only describe as "dimensional instability." Every wild encounter is a slot machine. Every trainer battle is Russian roulette with a Pokedex. I encountered a Corviknight on Route 101. A CORVIKNIGHT. I had a level 7 Wooloo. The math wasn't mathing.

FIELD NOTE: Wild encounters include the full Sword/Shield roster injected into Hoenn's ecosystem. Spawn tables are completely randomized. Prepare for anything.

The Galar species integration is... present. Sprites exist. They function. Some of them look like they were drawn during an earthquake, but they're there. My Toxtricity sprite has approximately 4 pixels dedicated to its mohawk and honestly? Respect for the effort.

POKEDEX VIABILITY ASSESSMENT

Here's where my eye started twitching. Living Dex is possible without cheats — technically. TECHNICALLY. But the randomization means you're at the mercy of RNG gods who clearly have a vendetta against completionists.

I spent 2 hours and 23 minutes hunting for a Dreepy. TWO HOURS. Found seven Stonjourners instead. SEVEN. Who needs seven Stonjourners? Nobody. The answer is nobody.

  • Gen 8 Pokemon: Confirmed spawning in wild
  • Evolution methods: Standard (no Link Stone implementation detected)
  • Trade evolutions: Still require trading. In a randomizer. In 2024. My blood pressure.
  • Mythicals/Legendaries: Randomized into static encounters — saw reports of Zacian replacing Rayquaza
MISSABLE EVENT WARNING! Save before entering the cave. Actually, save before entering ANYTHING. Static encounters are randomized and you only get one shot at whatever cosmic horror replaces your expected legendary.

QUALITY OF LIFE INFRASTRUCTURE

This is where the expedition gets painful to report. The QoL features are... vanilla Ruby. That's it. That's the whole sentence.

  • No infinite Repel system
  • No DexNav (obviously, wrong generation, but a man can dream)
  • No Link Cable item in Department Store — trade evolutions remain the bane of my existence
  • No built-in shiny rate modification
  • Running Shoes: Still requires button holding like it's 2002

The creator focused entirely on the randomization injection and called it a day. Which, look, I get it. Injecting 400+ new species into a GBA ROM is not trivial work. But my spreadsheet is CRYING.

SHINY HUNTING VIABILITY

Shiny hunting method: Full odds. 1/8192. No DexNav chaining (wrong engine). No Masuda Method implementation. No Shiny Charm.

I saw exactly zero shinies in my 12+ hours. Statistically expected? Yes. Emotionally devastating? Also yes.

If you're here to shiny hunt, bring a book. Bring several books. Bring the entire library. You'll be here a while.

POST-GAME ASSESSMENT

The post-game is... Ruby's post-game. With randomized Pokemon. Battle Tower exists with randomized rental teams that range from "accidentally competent" to "three Magikarps and a dream."

No Battle Frontier. No additional content beyond base Ruby. The randomization IS the content, and once you've seen a Dracovish replace a Tentacool, you've kind of seen the whole trick.

ANOMALIES DETECTED

  • Several Gen 8 moves cause visual glitches (Behemoth Blade displays as a white flash)
  • Galarian forms share sprites with their Kantonian counterparts in some cases
  • Dynamax references in Pokedex entries that obviously don't function
  • Some ability descriptions truncated or display incorrectly

No game-breaking bugs encountered. Crashes: zero. Soft-locks: zero. It's stable. I'll give it that.

FINAL EXPEDITION NOTES

Look. This is a randomizer. It does what randomizers do. You want to see a Dragapult fight Roxanne's rock types? This delivers. You want a polished, completionist-friendly experience with modern QoL? This is not that region.

My Pokedex sits at 31.2% and the thought of grinding that to 100% through pure random encounters makes me want to lie down. There's no hunting strategy here. No methodology. Just chaos and prayer.

100% completion would take me... I genuinely cannot calculate it. The variables are too random. 200 hours? 300? Depends entirely on whether RNG decides to bless you with that one missing Alcremie form or curse you with your 47th Stonjourner.

VERDICT: Fun for a chaotic weekend playthrough. Nightmare fuel for completionists. My spreadsheet remains tragically empty.
