>>53071738the text in the yellow box mentions how both the Gimmighoul line and the Treasures of Ruin were born from the accumulation human emotions. Gimmighoul was 'was born from passion that seeped into a coin' according to its dex entries.
only thing I'm not sure about this is Chien-Pao being listed as the water element but otherwise it's definitely interesting.
here are some of my own observations
it might be unintentional since Gholdengo is the #1000 Pokemon but he is followed by the legendary quartet (Wo-Chien is #1001 and so on..)
Their designs also feature the 'element' with some sort of inanimate object, for Gholdengo's case it's the treasure chest he wears as a belt.
the Treasures of Ruin are... treasures while Gimmighoul/Gholdengo get a literal treasure chest. the part about their designs might be too much of a reach but I'll be keeping this theory in mind.
