BioHazard was one of nine BattleBots competitors produced by Jakks Pacific in 2001 as part of their Battle Bashers line of toys.
The toy was based upon Carlo Bertocchini's title-winning heavyweight robot and is largely a strong representation of BioHazard's design. Due to the need for a friction motor, there is a small protrusion to the right side of the toy's primary weapon to accommodate this. Because of this, the biohazard symbol on top does not sit flush to the rest of the robot.
The BERG, PTC and RobotBooks.com sponsorship logos were included on the side skirts, though the latter was positioned towards the top of the skirts due to the way in which the toy's armor would 'explode'. The sponsor decals on the front of the real robot are also missing from this toy.
The toy's two drive wheels were powered by a friction motor and the iconic four-bar lifting arm could be activated by pressing on the back end of the lifter.
Due to Mattel owning the rights to the 'Biohazzard' Hot Wheels toy, the Jakks Pacific were forced to remove the robot's name from the toy's packaging, reissuing BioHazard under the name "Heavyweight Champion" for all newly-released BioHazard toys. The BioHazard name was also removed from the rear skirt of the toy, and replaced with two more BERG decals. On the sheet of instructions which show how to put the toy back into fighting form, BioHazard is listed as "Robot" on later releases.
As with other toys in the range, BioHazard had a trigger button which, when activated, would 'explode' the robot. In the case of BioHazard, its top armor would come apart either side of the primary weapon, revealing its internal components.
