I'm writing a novel that borrows basic elements of the MechWarrior universe, that is, the presence of "MECHs" on a fictional planet in a nation's military. It is strictly an influence, but could still be called fan fiction. In the actual writing there is no mention of the MECHs' names (I've given my own names for MECHs that correspond to some 'Mechs in the games), and absolutely no other part of the MW universe is included.
I'm more quizzical about the actual images of said machines. For example, if my book features the original illustration of a certain existing 'Mech on the front cover, absent of any symbols or text, is that infringement for when I self-publish to sell the book online? I also plan on having basic black-and-white outlines of MECHs within the first few pages. Among them is the Mad Cat, though I've renamed it, it does have that iconic outline most people would instantly identify with MechWarrior, but it is not featured on the cover and thus I figure wouldn't act as a selling point.
Thanks in advance for any helpful feedback.
