The Darkflame Ancient Raven, as the name suggests, was a special and powerful Pet Beast that carried both Dark and Fire Elements.
However, after devolution into a Flame-Eating Crow, the Dark Attribute completely vanished, leaving only its current Fire Element Attribute.
In Su Ping's speculation, to complete the reversion and become a Darkflame Ancient Raven, the Flame-Eating Crow would need to awaken its Dark Attribute!
This was confirmed by Toothy's condition.
Indeed, the reason Toothy was so weak was because its own Energy was abundant, and it was about to undergo reversion Evolution. However, it lacked the ancient Energy necessary to complete this type of Evolution!
