Vyvian, a Leafia and the only one in the Brotherhood of Nod.

When Vyv was a baby she was given to Kane. Kane wanted to have a pokemon who would follow him and the Brotherhood without question and Vyvian was trained and educated by Kane so she now believes in the Tiberium Future that Kane has envisioned.

Vyvian evolved into a Leafia after coming into contact with an odd stone which was later called a Moss Rock. Her new Grass Type body allowed for a successful Tiberium Fusion. The only side effect that this fusion gave her was that her eyes became green with red slit like pupils.

Her new powers of Tiberium were weak to start with but with training from Kane she learned that she could absorb the energy from Tiberium to increase her own power. She also learnt that she could heal almost instantly in the presence of Tiberium which would make her HARD to damage.

Unlike Nod-Flareon when he first had Tiberium-Fusion, she didn't create a split personality, she is completely in control. Tiberium appears to be very compatible with Grass or Poison Types.
