If you are talking about the water guardian found in water temples, there is no special way to kill it besides hitting it with a sword, bow, cactus, lava, or harming potions.
The Guardian
A guardian who lives with you
You can't exactly be a Guardian on AQWorlds, but you can verify on AQW that you have Guardian on the original Adventure Quest and get Guardian class in AQWorlds. :)
The Guardian was created in 1821.
