Summon Locations:

Choco Mog: Outside of Midgar, and Kalm, go to the Chocobo Farm and talk to the chocobo next to the fence. Watch the chocobo dance. You'll recieve the Materia afterwards.
Shiva: After you defeat Bottom Swell in Cannon town, and you've rescued Priscilla, she will give you the Shiva Materia.
Ifrit: This appears on the floor of the ShinRa ship after you defeat Jenova-Birth.
Ramuh: After defeating Dain, go back to the Gold Saucer. Ramuh is in the room where all the chocobo racers are waiting.
Titan: Located in the junk pile next to the town of Gongaga. Search the front of the ruined Reactor.
Odin: Appears on the floor of the Mansion in Nibelheim, after you defeat Lost Number. (pops out of the safe)
Leviathan: In Wutai, you must first defeat Yuffie's dad in order to obtain Leviathan.
Bahamut: Appears in the Black Materia Temple, after you defeat Red Dragon.
Kjata: In the Enchanted Forest (through Bone Village), the Materia is roaming around in a pattern. To catch it, press O .
Alexander: During the glacier portion of the game (disk 2) touch the hotsprings. Then, from the cave with the tent inside (south of the cabin/save point), go east (south takes you back to the glacier area). You'll come upon a cave with a woman in it. Touch her, causing a battle. Kill her and win Alexander.
Phoenix: After completing the simulation portion at Condor Tower, go to the top of the tower to find it.
Neo Bahamut: During the begining of disc number 2, you'll locate this one on your way to the crater where Sephiroth is.
Hades: Located in the sunken airplane. You must have the submarine in order to retrieve this Materia.
Typhoon: (Chupon) Once you kill Ultima Weapon he causes a crater in the ground. You'll then be able to get to Frog forest. Go to the third screen and climb the tree and go all the way right. You can get it before Ultima Weapon makes the Crater, with the Mountain Chocobo.
Bahamut ZERO: The large Red Materia gives you access to Bahamut ZERO. (in Red XIII's hometown)
Knights of the Round: Found in the cave which is located on the northeast portion of the map. You need the gold chocobo to get into the cave. It's hidden on the map.
