Step I - Brainstorming[]
Find other articles. If you see any of them you like, maybe not everything, just an outstanding and good part of them, add it to a list, probably a notepad or something. You can do this by using Special:Random. Once you have 7-10 main features of your entity, it's time to make your page.
Step II - Designing[]
So, most entities use the {{Entity}} template. Apply it and then fill out the parameters with your desires. Then, you design your character and upload it. Time to do sections.
Section A - Description[]
What does your entity do? Which great (or bad) features does it have? What does it look like? (Clarify instead of letting the PNG/JPeG do its thing). Why does it exist? Those are the main questions you may want to answer. Add the Heading (Ctrl + 2) and then insert "Description" above your, well... description.
Section B - History[]
Expand on "Why does it exist?" What happened to it? Why does it look that way? Perhaps a scar from a war? A robotic arm from a Wolfus at the farm? I don't know, you do it! And maybe it did some cameos in shows, like Mogusman Story. Make some cool fantasies.
Section C - Abilities[]
How powerful is it? More powerful than a Crewmate? Less powerful than a pigus? What can it do? Destroy an entire Galaxymogus? And which field does its powers end and start? For example, it could control three Impostor's minds, but cannot defeat a Cocodrilus. Psychology and physicality are different.
Section D - Trivia[]
Add some cool things about them that are kind of not relevant enough to be in the other sections, but still should be included. :)
