Well, as you know the three models made by Water Warriors of the Aqua Master Pre Charge System were the Argon, Xenon and the Krypton. I was doing a bit of browsing
here until I noticed the hosting plans had the same names as them, this is just a thought so don't flame me like a crazy person would, but Buzz Bee Toys may have got the name ideas from here, they fit pretty well for each gun, like the Argon being the smallest in the Pre Charge line, which is also pretty small on the hosting plan, the Xenon is the next biggest after the Argon in both the series of guns and the hosting, finally, the Krypton is the biggest of both things too. So, maybe there is some resemblance. That's just my thought.
