A kid from a rural New York town uses an ancient sceptor to bring rain to a town that's been dry for the past two months. However, the beast the sceptor helps summon can control the rain, wind, and lightning. The beast is VERY difficult to control, and will sometimes turn on the user. Before they boy can send the creature back, lightning strikes the incantation, burning it to smithereens. The EGB's are called into help, but are refused to see the sceptor and study it. Slimer sneaks in, and takes it to them. In the meantime, the 'busters are trying to stop a tornado the creature produced, creating all hell in the middle of the city. The sceptor enhances the proton energy, and the 'busters are able to get it trapped, but "sister twister" remains. How do they stop an F3 tornado?
