Mecha:
Mecha, which means "mechanical power armor" and Japanese name is メカ, generally appears in sci-fi or surreal movies, games and novels, and some people try to create this technology in reality. The word "Mecha" basically refers to power suit who is similar to Iron Man. Mecha itself is a foreign word, meaning: Utopian mechanical device. Because the early translation in China is not clear, many sci-fi works are translated by directly applying the meaning of Mecha, which is first known to the audience and then accepted.
