Freezies are going to return in the upcoming Super Smash Bros (3DS). They have the ability to freeze players solid after getting hit by one.
Modded Characters Edit
There are a number of character mods available for Super Smash Bros for Wii U. You can find most of them online at the Gamebanana website. There are also dozens of tutorials on how to easily install mods, and get them working correctly. More character mods means more characters to freeze with the Freezie!
