How Do You Evolve an Onix Into a Steelix in the Game "Pokemon FireRed"?
- 1). Place "Pokemon FireRed" cartridges in both Game Boy systems and turn them on.
- 2). Purchase a Metal Coat from a Pokemon Mart and equip Onix with it.
- 3). Travel to a Pokemon Center. Remove Onix from the Pokemon Center's PC storage system. Make room in your party if needed by storing another Pokemon in the PC.
- 4). Place your Game Boy parallel with another to activate the infrared link technology. This allows you to trade Pokemon.
- 5). Talk to the man behind the counter to begin the trade. Give Onix to the other Game Boy. He will evolve into Steelix as soon as you do so.
