Ponymon that can learn this move are:
"The foe is attacked with an odd, hot energy wave that varies intensity."
Chaos inflicts a random amount of damage, varying between 0.5× and 1.5× the user's level. The damage can be calculated using the following formula, where X is a randomly generated number between 0 and 10:
(X + 5) × (User's level / 10)
Damage will always round down and it always greater than 0.
Disclaimer: More ponies may need to be added with more expansions.
