National Dex, Celio, Ruby, and Mt. Ember Return section for the FireRed and LeafGreen walkthrough with source-backed wild Pokemon, trainers, items, hidden items, bosses, and route notes.

By Damodar Sharma Updated June 24, 2026 Walkthrough

After the Hall of Fame, obtain the National Dex if you have enough owned Pokemon, return to Celio, receive the Rainbow Pass, and retrieve the Ruby from Mt. Ember's Rocket path. This page is a standalone section for Phase 10: Post-Game Sevii Islands, with FireRed/LeafGreen source data for encounters, trainers, items, hidden items, and boss routing.

Route plan

The Network Machine needs both Ruby and Sapphire. Mt. Ember's Rocket path opens the post-game Sevii arc.

Route Notes

  • Celio gives the first Rocket password after the Ruby step. The second comes from the Sapphire theft event in Dotted Hole.

Wild Pokemon

Version

Each area below has its own table, split by encounter method. Standard wild rows merge every slot for a species into one line with a combined rate, and FireRed/LeafGreen exclusives are marked with FR/LG game chips; there is no time-of-day split in these remakes. Underlying slot odds: grass and cave 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Rock Smash 60/30/5/4/1; Old Rod 70/30; Good Rod 60/20/20; Super Rod 40/40/15/4/1. Gift, static, trade, and prize Pokemon keep their own labeled rows.

  • Sweep visible and hidden item rows, including key items, HMs, TMs, berries, fossils, and scripted gifts.
  • Review boss cards and heal before any Rival, Gym Leader, Rocket Admin, Elite Four, Champion, or legendary encounter listed above.
