Pokémon Eternal X is widely considered one of the definitive "difficulty and enhancement" hacks for Generation 6.

Pokémon Eternal X Guide (Verified): The Ultimate Walkthrough & ROM Hack Tips

Last Updated: October 2025 | Verified Working

If you thought Pokémon X was too easy, you haven’t played Pokémon Eternal X. This renowned ROM hack by Buffy Silver turns the Kalos region into a brutal, high-level battlefield. But with so many fake downloads and outdated strategies floating around, you need a verified guide.

In this post, we cover:

Let’s dive in.

Part 2: Choosing Your Starter

In vanilla Pokémon X, Chespin, Fennekin, and Froakie suffice. In Eternal X, your choice dictates your early-game difficulty.

  1. Froakie (Water): Recommended. Greninja is a monster. With Protean (its hidden ability, obtainable early) and high speed, it acts as a sweeper that can hit anything for super-effective damage.
  2. Fennekin (Fire): Hard Mode. Delphox is solid, but early game rivals (especially Shauna and Tierno) have teams designed to punish Fire types.
  3. Chespin (Grass): Intermediate. Chesnaught is a tank, but its Fighting/Grass typing leaves it vulnerable to the heavy Flying and Psychic usage by mid-game trainers.

Pro Tip: Don't stress too much. You can catch a Chimchar, Torchic, or Mudkip on Route 2 almost immediately. If you struggle, soft reset for a starter with a beneficial Nature (Jolly/Adamant for physical, Modest/Timid for special).

The Lumiose City Gauntlet

Professor Sycamore’s battle is infamous. He has a Level 100 Arceus? No (that’s a myth). But he does have:

Verified counter: Use a single strong Pokémon. Mega Lucario (given after the battle) is bait – you need it for the battle? No. Instead, catch a Ralts on Route 4. Gardevoir with Psychic OHKOs all three.

VS Viola (Gym 1 – Santalune City)

Her team is brutal:

Verified Win Condition:

  1. Lead with Pikachu (Route 3 – 10% spawn). Use Nuzzle to paralyze Scizor.
  2. Switch to Fletchinder. Use Acrobatics (no item).
  3. If Vivillon puts you to sleep, wake up with a Chesto Berry (bought in Santalune).
