The same goes for ones that are blatant attempts to become the strongest ever.
Generally a monster can have as many abilities as its creator sees fit, but too much power or too many abilities eventually comes to a point where the monster with them is boring and no fun to see around. If it's going to be a monster, it needs some kind of special ability, be it physical or supernatural. Psychic powers, fire-breathing, flight, troll-flailing, the power to point at randomness itself, etc. Make sure there's some kind of special abilities at work. Perhaps the most obvious thing is that a Freak or Monster without abilities might as well not be a Freak/Monster at all. Instructions 1: Give it a reason to be a Monster at all. Don't just assume things will be canon just because you say they are! Make sure there exist videos, and that they don't degrade the quality of the monster they present. If you make a backstory, make sure it isn't contradictory. Avoid making copycat or mix-and-match pony freaks.
Give your monster some kind of weakness or flaw! 1.1 1: Give it a reason to be a Monster at all.
