The original Water Warriors Xenon was released back in 2005. The 2016 version of the Water Warriors Xenon by Alex Brands Buzz Bee Toys Holdings appears mostly identical except that the pre-charger toggle button is now replaced by a lever-switch. Testing is needed to see how similarly this new version compares to the original.
Unfortunately, at present, there is no sign of a 2016 Version of the Water Warriors Krypton.
