Emerald Legacy Evolution Levels: What Changed, and the Full Level List

Every level-up evolution in Emerald Legacy in one table, plus the ten species that now evolve earlier than in vanilla Emerald -- Slugma at 27 instead of 38, and the rest.
Compiled from Emerald Legacy's extracted ROM data
Last updated: September 27, 2026

Two questions this page answers that the main evolution guide doesn't: which evolution levels Emerald Legacy moved from vanilla, and what level every single evolution in the ROM actually triggers at.

The short version of the first: ten species evolve earlier here, none evolve later, and 13 more had their method swapped (all the trade evolutions -- that's on the other page). The rest of Emerald's level curve is untouched.

The one that changes how you play is Slugma → Magcargo at 27 instead of 38, because Slugma is a 20% spawn on Route 113 -- you can have a Magcargo before badge four in this ROM, and it's a serviceable answer to Flannery's gym if your starter is the wrong type. Aron → Lairon at 28 matters for a different reason: Lairon doesn't become Aggron until 42, so the earlier middle step keeps the line usable while you wait.

What to take from that table

  • Level 16 is the busiest rung. Every starter's middle stage is there, plus Ralts, Abra, Nidoran and the Kanto and Johto starters you can pick up later.
  • Level 36 is the second big one, and it's where the final starter evolutions land -- Sceptile, Blaziken, Swampert, plus Charizard, Typhlosion and friends.
  • The last evolutions in the game are at level 55: Dragonair → Dragonite and Pupitar → Tyranitar. If you want either, you're raising it deliberately, not picking it up along the way.
  • 42 is the trade-family replacements -- Alakazam, Gengar and Aggron all land together there, which is later than most players reach on a normal playthrough.

Where these numbers come from: a full diff of Emerald Legacy's extracted evolution chains against vanilla Emerald's -- all 184 shared evolution entries, 10 level changes and 13 method changes, with nothing else different.
