The Game Boy Advance release adds four espers and two optional endgame challenges.
Bonus magicite
After recovering 
Edgar in the World of Ruin, speak to the man near South Figaro and take the ferry to encounter Leviathan. Bring 
Mog if you need the water-terrain dance; prepare for a difficult water-element encounter.
In the desert near Maranda, defeat ten Cactuars and seek Gigantuar for Cactuar magicite. In Jidoor, obtain Excalipoor from the auction and wager it at the Colosseum to face Gilgamesh. These fights are optional and are much harder than early World of Ruin encounters.
Dragons’ Den and Soul Shrine
Defeat all eight original legendary dragons to unlock the Dragons’ Den. Form three prepared parties and bring recovery items: the dungeon has stronger versions of the dragons and switch-based routes. Defeat Kaiser 
Dragon to obtain Diabolos.
The Soul Shrine becomes available after completing the game and defeating Kaiser Dragon. Its successive battle sets are an endurance challenge; save outside and prepare a broad range of recovery and equipment. Neither dungeon is present in the original SNES, PlayStation or Pixel Remaster releases.
