How do you get off of island one in Fire Red without strength?

You can't get off Island One in FireRed without Strength. It's the only way to move the boulder blocking the path to the next area.

Here's why:

* Strength is essential: The game's design intentionally requires Strength to progress. It's a core ability introduced early on to encourage exploration and puzzle-solving.

* No alternatives: There are no hidden pathways, glitches, or other methods to bypass the boulder without Strength.

Here's what you need to do:

1. Talk to the old man in the house on the right: He'll give you the HM for Strength.

2. Head to the Pokemon Center: You'll need to teach Strength to one of your Pokemon.

3. Return to the boulder: Use Strength to move the boulder and access the next area.

Once you have Strength, you'll be able to explore further and continue your journey!
