Relic Mystic is kind of like a dark form of her. She's like dark sonic only much more powerful! She has only one personality which is Determination.
As you read, relic Is like a dark form of Mystic, Using all seven Reloc Emeralds. She knows Which foe she's attacking, but when it's defeated, She attacks everyone near her using relic Blast.
Relic Mystic's attacks are all about darkness(her name doesn't really Sound like darkness). She can also use fire and lightning attacks.
Her only weakness is calming down, hugging, kissing and other Calming things. But mostly light...
