Ultimate Blasters

Ultimate Blasters is a sub-series of Buzz Bee Air Blasters dart blasters that was released in 2010.

Details
Blasters released within the Ultimate Blasters series featured the ability to connect to one another. Blasters were denoted with what order they were attached; "A-Type" are top blasters, "B-Type" are middle blasters, and "C-Type" are bottom blasters.

This idea was continued within the Air Warriors series with the use of Power-Lock connections, and blasters within the Ultimate Blasters series are compatible with connecting to other blasters with Power-Lock connections.

Trivia

 * Buzz Bee had a similar series of water blasters that connected together, but did not feature the same "A/B/C-Type" system, as each blaster could connect to each other, no matter whether it was smaller or bigger than the connected blaster.
 * The sub-series is also referred to as the Ultimate System on blasters' packaging.
