Like I want to develop this app which is like the Pokemon Dex but for anime characters and I can't draw and even if I could, it would be technically using the art from the anime character creator. I want to monetize it so I am able to upgrade the backend as the character's info is with help from the community, like Wikipedia. I am planning to monetize it via Google Ad Services, but I want to make sure I am doing everything legally. Help would be nice.
Unless you really have a license, you would be lying by crediting them in the license section.
No. See who owns the art and try to get a license.
You can also hire somebody for original art.
Best luck
