Peridot turned to her true form which is that of a Ryujin which delighted the Goddess Tiamat as she was watching from the sidelines as well. She decided to watch because her children as going to be fighting and she wanted to see the exceptional one which is Peridot.
Peridot's serpentine form looks completely different compared to before because she actually underwent evolution. She still has the serpentine dragon look but she now looks divine compared to her previous look. Her scales are pinkish in color that made it look like they are made with pearls while her hair that flowed freely looked like silver strings.
