Getting Odin in Final Fantasy 7 is very easy. Requires you to be in the Shinra a second time. The first time, of course, in the flashback in the city of Kalm when you first leave Midgar.

Once you enter the mansion, there are 4 clues scattered throughout. Each one will give you a hint for the safe combination that is on top. If you want to know every clue and where to find each one, you are probably reading the wrong article. I’m just going to cover the actual combination itself. To get to the safe, enter the mansion and go up the stairs. Now head to the left and then go up to the north room. The safe is against the wall.

Don’t miss any numbers or it won’t work. The combination is Right 36, Left 10, Right 59, Right 97.

After entering the combination, you will automatically engage in a fight with a boss named Lost Number. It is made up of 2 monsters, a red side and a blue side. The red side casts magic and is obviously very resistant to your spells. The blue side only attacks physically and is of course resistant to physical attacks. The boss will turn into a single monster after a certain amount of damage. Which side, blue or red, depends on which type of attack of yours last hit. A physical attack will give you the blue monster and a magic attack will give you the red one.

The easiest way to kill this monster is to hit it with summons and magic. Limit breaks will also help a lot. This will cause it to turn into a red monster that is very vulnerable to physical attacks, so all you have to do is hold down the circle and watch your party’s health.

Upon victory, you will find a red ball on the ground. This is Odin’s Summon Materia. Just pick it up and it’s yours. You can now summon Odin in any battle.
