The Century Fox is a creature that lives 100 years old before giving birth, and dies once the cub is born. It is said there are only 20 of them on Earth at a time, and for every one some stupid hero kills, another one is born from it's ashes.
WARNING! Do not feed a Century Fox a banana! They are highly sensitive creatures to the color yellow. Anything yellow is poisonous to them. It will make them go into an uncontrollable rage and kill anything in sight. I warned you, so don't say I didn't.
How to beat them
The easiest way to defeat a Century Fox is with feet. Defeating things with feet is simple, so simple that heroes don't think about it. Lie on your back and kick your feet like you're biking. It's that easy!
