The process to unlock this secret boss isn’t too complicated, but it can be tricky if you’re unsure of what to do or if you don’t understand the game’s language. Defeating the boss is a different challenge altogether, but if you’re struggling with that part, you can skip to the next section for battle strategies.

Steps to Unlock the Battle:

1. Play Through the Game Normally
   Progress through the storyline until your party consists only of Goku, Krillin, and Gohan, which happens after defeating Nappa.
2. Collect All Seven Dragon Balls
   • Return to the world map, where you’ll notice seven locations marked with sparkling crosses.
   • Equip the “Dragon Radar” capsule (hold the Y button) to locate the Dragon Balls.
   • The balls are usually found in the deepest part of each dungeon in those areas, and the radar makes them easier to find.
   • Since their locations are random, exact spots can’t be pinpointed, but the radar will guide you effectively.
3. Make a Wish After Collecting All Dragon Balls
   • Once you’ve gathered all seven Dragon Balls, you’ll be granted a wish immediately.
   • Choose the sixth wish (or the last one, depending on previous wishes) to unlock the secret boss battle.
   • After making the wish, the Dragon Balls will scatter again, allowing you to collect them for additional wishes if you choose the wrong one.
4. Locate the Boss
   • Return to the world map and head to the southeastern area of the main continent, near Goku’s house.
   • You’ll see two similar areas; enter the one on the right.
   • Turn left at the bridge, exit the next area via the upper exit, and keep walking until you see a wooden sign pointing right.
   • Follow the path to the right (be cautious, as enemies here are very strong, and random battles are frequent).
   • Continue until you reach a large rock formation shaped like a dragon’s head, where you’ll find a purple portal.
   • Save your game before entering the portal to start the battle.
