Template:All Game Nav In Sootopolis City the weather has gone awry. If you are playing Ruby, Groudon is causing strong sunshine, or, in Sapphire, Kyogre is causing heavy rain, each of the two Pokemon searching for the other to kill it. You must stop this.
Go to the northwest of Sootopolis City. Steven will meet you and introduce you to the Gym Leader Wallace. on seeing the Orb that you're holding (Red Orb in Ruby and Blue Orb in Sapphire), Wallace takes you to the Cave of Origin.
The Cave
It is dark inside the cave so bring a Pokémon that knows Flash to light it up. The cave is shaking due to the roars of the legendary beast. Inside a misty chamber, you'll find HM07(Waterfall). Grab it and simply continue down the ladders. At the bottom of the cave, you'll find the mighty Pokémon. Your Orb will start glowing as soon as you stand face to face with it. So save the game before that. This is a must, because here awaits your ultimate dream. And you must pursue it, bearing some failures.
The Orb will strip the legend of all the powers that the criminals of the game (Team Magma or Team Aqua) had give it. In a rage it attacks you. It's battle time.
Battling Groudon
Paralyse Groudon first of all using the Stun Spore move. Note that its ability Drought brings bright sunshine on the battlefield. The TM move Solarbeam works faster in sunshine. So use this attack once to blow away more than 90% of Groudon's HP(your Pokemon should be at a lower level than Groudon[Level 45], or else Groudon gets knocked out!). Preferrable is to preserve this TM and teach it to Groudon after it's caught. In that case, use gentle Water type attacks like Water Gun, again of a weaker Pokémon. Or use Rock type attacks as they cause little damage to Groudon.
