This monster appears when he peeks out from behind the Incognito.
Translation: Gold Shield
From Chrono Trigger Ultimania, translated by Lorenz:
In the Black Dream there is a monster who goes by the strange name of “AU.” At first glance you may think this mean “hero,” but the truth is that the golden shield braced before the shadowy figure is also one part of the origin of this name. In the Periodic Table of Elements, gold is represented by the symbol “Au,” so that is where his name is derived from. (Gold shield – Au Shield – “AU”)
(NOTE: Ok. This one is tricky and may require a bit of Japanese knowledge and a gander at the original scan to understand. Also, I honestly don’t remember what this guy’s name is in the English version anyway; so that only further impedes my ability to explain this satisfactorily. Moral of the story is the enemy’s name is a really lame pun. In Japanese, a lot of words with different meanings sound the same; a fertile ground for punning. The big joke here is that in katakana the enemy’s name is “eiyu-“ which shares its pronunciation with the two-character kanji meaning, basically, “hero” or “brave person.” So a Japanese person would probably assume that was the meaning. However – and here’s the real knee-slapper – it turns out that they named him that because they were trying to awkwardly transliterate the Periodic Table symbol for gold, Au, into Japanese. Get it? He has a gold shield and… oh never mind… Let’s just get to the big finish, shall we?)
