I'm looking for intellectual properties that are about mechs. Now, Mecha Break, Metal Gear Solid, and Frame Arms are the only intellectual properties I can find, thus far, that have no spirits, aliens, demons, gods, or spiritism.

Do you know of any anime, manga, movies, or TV shows with giant robots, and none of that garbage? I need to know because I'm getting a detolf and filling it with robots and kaiju.

Yes, I don't like spiritism. Can you blame me?
