How to obtain the Secret GFs
There are a few secret GFs in Final Fantasy VIII; Bahamut, Cactuar, Doomtrain, Eden, Odin, and Tonberry. Here's how to get them;
BAHAMUT: Fly the Ragnarok all the way Southwest and you'll eventually run into a place that looks like ruins. Enter this place and then enter inside. DON'T MOVE if the core is glowing, if you do you'll be forced into a battle with a Ruby Dragon. Now, when you reach the core, press X. Now choose the most bravest choices for the answers. No matter what, you'll have to fight Ruby Dragons. On the final question, go all the way down to the invisible answer and choose it. Then you'll be forced into a battle with Bahamut. If you beat him, you get him!
CACTUAR: Fly the Ragnarok to the little Island off of Kashkabald Desert, this place is called Cactuar Island. Now, do you see the little Cactus that keeps popping up out of the sand? Well, if you reach that, you'll be forced into a battle with Jumbo Cactuar. Jumbo's weak to Water, but he's got a MAJOR load of HP! I suggest having Squall, Irvine, and Quistis in your party, all with their ultimate weapons. For beating Jumbo, you get the Cactuar!
DOOMTRAIN: If I remember correctly, you have to have these items in your inventory;
-Solomon Ring (x1)
-Malboro Tentacle (x6)
-Steel Pipe (x6)
Remedy+s can be made by refining 60 Remedies into Remedy+s. Malboro Tentacles can be mugged from Malboros, refined from Malboro Cards, etc. Steel Pipes are mugged from Wendigos, which are found in Timber's Forests and Deling City's Plains. Now, with these items in stock, head to Tears' Point and pick up the shiny thing near the Statue. This is the Solomon Ring. Now, pause the game, select Item, and select the Solomon Ring. You now have Doomtrain!
EDEN: Remember a while ago you had to fight Bahamut? Well, return to that place and travel all the way down to the basement to encounter Ultima Weapon (for digit usage guides, refer to the walkthrough section). MAKE SURE SOMEONE HAS DRAW BEFORE FIGHTING HIM! This reason is because you can only DRAW Eden from Ultima. Beat Ultima with Eden drawn to get Eden, the Ultimate Guardian Force!
ODIN: Somewhere near the Southern Mountains lies a Diamond-Shaped Pillar. Enter this pillar to find a time limit (for a guide on opening the door to Odin, refer to a Walkthrough). Once his door is opened, he will say, "The Weak Shall Perish. The Strong Shall Triumph." Now, Odin is by far the most EASIEST boss EVER known, because he never attacks you until the timer runs out. If the timer does happen to run out, he will kill you. Defeat him to get him!
TONBERRY: Don't leave the place you fought Odin at! Return and you'll soon find yourself in battles with Tonberries. Eventually, after fighting enough Tonberries, you'll encounter the Tonberry King! Defeat him to obtain Tonberry!
