Leon
About
Leon is Lena's "partner", capable of transforming into a ferocious beast and mirroring Japolo's powers. Leon has a preternatural attachment to Lena and will defend her regardless of the risk to himself. He is only moderately powerful, but Lena can lend him her powers via her flute. (Source: Wikipedia)
