The Willwalker

The Willwalker was an undead skinwalker who had taken the shape of The Bear. He was an imperfect copy however, and as such his fighting style was affected more by his undead state than The Bear's. It is unknown how he came to be, why he took the form of The Bear, or what his goals are. Early on in season 1, he dominated the mind of Maxwell, making him his minion.

During Extreme Rules, The Willwalker not only defeated, but killed John Cena. Nobody dared step up to ban him from the BWF. Although the blame initially fell on The Bear, it was quickly discovered that the Willwalker was not the original.

Zerkermania 1
After a long feud with The Bear, The Walker finally challenged him to a battle to the death at Zerkermania 1. Although he fought with much spite and ferocity, he was ultimately beaten back, and was left cold, dead and crumpled, buried in a shallow grave.

Was it finally his time to rest?
