Freeze Ray

Freeze Ray (フリーズレイ) is Ice Man's secondary weapon. It takes the form of a beam of shatteringly cold energy, similar to the "Kamehameha" from the Dragon Ball series. It's also capable of freezing enemies within a few seconds of exposure.

Mega Man (Ruby-Spears)
Mega Man obtains Freeze Ray in the cartoon show. When Ice Man uses it, he fires it normally his hand. He is also capable of charging it up with both of his hands, similar to the Hadoken.
