Leon, the Lion.

Leon is a animatronic created circa the 90's, and even tough being a lion, is a complete coward.

In the band, he plays the drums, but the thing is he plays it backstage, because he is afraid that if he misses one thing, all the kids would know he did it wrong and would do something to him, but again, it's just his imagination.

His behavior is different every night, on night 1, he doesn't do anything.

On night 2-4, he slowly moves to your office.

On night 5, he starts running, but unlike Foxy, you know when he is coming, because you can hear him playing the drums. The only way to avoid him is using your flashlight AND your Freddy Mask,(Hold CTRL and then use the Freddy Mask) On night 6, shit gets hard, again, he runs to your office, and now you only need the freddy mask, BUT the thing is, he attacks only AFTER you escape another attack, like, let's say, Bonnie appears, you put the Freddy Mask on, but after he attacks and Leon is near the office, exactly after you use your mask to fool Bonnie, he appears right after, so hold on to your masks, and you will probably survive.
