Please hesitate from uploading renders (the cutting out of pieces of screenshots from any of the Ben 10 shows) in the future. They are not allowed here, as are not the others dissuaded from being put up that are listed here.
Lakshya.jaiswar, when putting a link on a page, say to Rook's page, put the following [[Rook Blonko]], just without the nowiki things either side. If you want the link to say something else like Rook, put [[Root Blonko|Rook]].
Sorry if it is unneeded Blaziken rjcf but I want to be helpful.
It's not unneeded, but I wanted to keep it as intuitive as possible. By clicking the "Add link" button, you get two text fields: one for the page you want to link to and the other for the text you want to display. IMO it's better for someone who doesn't know stuff like what you posted.
Second warning. You've been told how to properly add links in two different ways. Either you didn't understand, which means you shouldn't be trying to add links (or maybe shouldn't be editing articles at all), or you don't care. Either way, it constitutes vandalism, which can and will get you blocked.
Power categories ("Highly Durable Aliens", "Strength Aliens" and such) are only used when an alien's main power is the power in the category. For example, Diamondhead gets "Highly Durable Aliens", but not "Strength Aliens".
