Rolf the Tasmanian Wolf (or Thylacine)
Status: Know to science.
Extinct 1936.

Rolf now lives in the rocks by the entrance to Infinity. He doesn't trust humans at all, because they hunted all of his kind until he was the only one left.

The last Tasmanian Wolf, apart from Rolf, was captured and kept in a zoo, but she was not looked after and kept outside her shelter in extreme weather conditions.
