In 2258 of the alternate reality, a drakoulias attacked James T. Kirk, who was marooned on Delta Vega. Before the drakoulias could reach him, however, a hengrauggi burst out from the ground, grabbed the drakoulias, and threw it into a mountain. (Star Trek)
The drakoulias was designed by Neville Page. It is named after Star Trek music supervisor George Drakoulias. Its name was not referenced on screen, but comes from official production sources and is used on licensed products for the film.  The film's production team also called the animal a "polarilla", as it was designed as a cross between a polar bear and a gorilla.  It was called a "polarilla" in the script of the movie, which also described it as "horrifying" and, more specifically, "an eleven foot-tall cross between a polar bear and a gorilla."
