A Dhole experiment was stationed at the Oil rig. Keegan O'Neil sicced it on James Zanasiu, Sharon Varma, and Keith Bailey in his attempt to escape them. The experiment was coated in a titanium skin that made it largely impervious, and could attack with its razor-sharp claws.
It had a weakness under its chin, which Sharon took advantage of when a lucky trip by Keith Bailey exposed the weak spot. However, the experiment sufficiently delayed the two that they lost track of James and O'Neil, forcing James to fight O'Neil alone. (Disruptive Selection)
