This Pokemon is pretty Serious by nature.

We first met one another in the Giant Chasm!

It is somewhat vain.

At the time, this Pokemon was Lv. 70.

Bestla is a Kyurem Korey met in the Unova region. She is known to be cold towards others, but is quite serious when it comes to wanting to be whole with its missing halves, or when winning in a battle. No thanks to Ghetsis, she got a taste for her missing half, but couldn't revel in the success due to being defeated shortly afterward. She curses at Ghetsis before she flees to recover, showing up once more after Korey defeated the new Champion of the Pokemon League and when he got N's Reshiram after besting him underneath N's Castle. After a tought battle, she joined him in his travels, now able to transform into either her Black Kyurem or White Kyurem form at any time with the DNA Splicers.

Bestla has fused with Reshiram, the Pokemon of Truths that chose N two years ago, and had given to Korey to capture two years later. In this form, Reshiram and Bestla's voices speak simultaneously, almost as if the two are in sync. She justifies her actions as doing it for the truth, giving cold, dead glares to her opponents, facing them with no mercy. Glaciate becomes Ice Burn and Slash is replaced with Fusion Flare, Reshiram's signature move.
