I don't think it is canon since it includes characters like Paramount Sonic as Baby Sonic and Teen Sonic we also have Andronic. Also we have crossover characters like Pac-Man, Hello Kitty and Angry Birds so ı don't think it's canon to the main universe.
Wow wow I doubt non-canon aliens should be on this wiki. Even if they are allowed, he should also not have the Ben 10 aliens category since quite sure that category is reserved for canon aliens. Also where is Bob the Blob even from?
I also managed to save your Ben 23 profile but from before DemonicDude edited it and I also copied Bob the Blob in case it gets deleted, I'll put them under here. Also if you are wondering what source code is: Go to your own profile icon -> my preferences -> Editing -> Preferred editor and choose Source editor, then save those settings. It is recommended that you always use Source editor. Go to Common Editing Mistakes for more information.
Now if you want to make a blog with these, you can press quote to get the source code, remove all the unnecessary code indicating that you copied it from me (such as Greenshifer wrote: and </div>) and then copy it to your sandbox, you can have multiple sandboxes by entering a number after the word sandbox in the URL.
Also most staff have the capability to roll back pages, so even if it gets deleted, they can restore it so there is no harm in trying, just don't make it an actual page without someone first checking it.
Kindly utilize source mode editing. You can change this to your default editing mode in the preferences settings. Feel free to overview this image to observe a basic example regarding how to properly write profile pages in this editing mode.
Behave in a civil and unbiased manner, and do not spam, troll, threaten, or use offensive language.
Use correct grammar and spelling to the greatest extent possible.
