Sky

(for those who don't know)Bloom is not just a fire fairy, Bloom is fairy of the dragon flame, she is daughter of the king and queen of domino, she's not from earth, she can control her fire but can't control her dragon flame, the proof is in season 7 when Kalshara weakens the dragans in paires, while Bloom remember her memory(in s2) that show how she summon her dragon flame, but the dragon she summon is dangerous, so she killed her dragon she summon, that's the reason why Bloom just like always dying when Icy attack her, and dragon flame is the power who created the whole magical universe
