The Killer Bee was a limited edition award yo-yo made by Playmaxx. Identical in design to the ProYo Turbo Bumble Bee, the Killer Bee was a special run produced in solid red plastic with special Killer Bee side pogs. These were never made for retail sale, as they were only available as prizes for contest winners at ProYo-sponsored competitions, making it one of the most sought-after ProYo collectors' items.
The story goes, is that Tom Van Dan Elzen, who is the head of Playmaxx, wanted to produce a run of Turbo Bumble Bee yo-yos in the same color as the original brick red ProYo (the company's first release in 1976). Unable to precisely match the color with the available plastic dyes of the 1990s, they had instead taken a handful of original ProYos and melted them down in order to mold the Killer Bee yo-yos.
