Im assuming this means "Club Penguin Water Ninja army" right?
I feel like Im being a minimod here closing threads and answering stuff professionally (like this) this past while but no. This is not the place for those "wars" or whatever. Or anything fandom related really as there are many different interpretations. There are fandom wikias for CP armies and such if you want to add that stuff. If Im misinterpreting your question entirely heres a different answer: add whatever the heck you want on your userpage but not in the mainspace.
Personal opinion here: I personally dont like these so called armies as real life armies are a serious issue yet people on CP act like its all fun and games as well as the fact its defeating the purpose of Club Penguin. The purpose is to be a community. (I also dont like those one day old P(numbers) accounts that sit around in the Town or whatever and advertise all day)
I guess I won't add any pictures. Also advertisers are called "auto-typers"
