-An example of a machine is like the Mecha. They are machines that are piloted by humans, or are sentient on their own, like transformers, Gundam, Knights and magic, Code Geass, Neon Genesis Evangelion and more. Mechas are often included in war or combat, and if the mecha isn't the main part of the show or book, then they will usually be smaller or designed to be more lightweight. Instead of letting the person pilot the machine by stepping inside of it, a person wears a certain suit that can transform into different weapons, like in Cyberpunk 2077.
