Weather Crystal, misspelled "Weather Cristal" in Mega Man X2, is a spherical crystal that controls the weather in the Weather Control Center, Wire Sponge's stage in Mega Man X2 and Mega Man Xtreme 2. Not technically an enemy, they stay over a purple crystal pillar, and through them, X can change the weather at will. The weather greatly affects the behaviour of all enemies except Aclandas and Scrivers. In addition, the rainy weather also affects X's mobility, adding constant velocity to the left (not affected when stationary on the ground).
