The ProYo Ace, released in the late 1990s, is a metal yo-yo produced by Playmaxx. It is essentially a mini-sized Cold Fusion GT, using a thin variety of the standard Brake Pads, similar to the Stunt Pilot offstring yo-yo. It was one of the only miniature aluminum yo-yos that Playmaxx produced before its acquisition by Duncan. Available in various two-color combinations, it was also distributed in limited gold- and nickel-plated finishes with no logo or branding. The Ace would be followed up with the Ace II.
The Nuclear Ace, a limited edition of the standard Ace, was produced with a unique, glow-in-the dark powdercoated finish, and had a run of 100 units, which were sold exclusively at the 2000 ProYo World Championships.
