I was playing the Heroic adventure "A Bug in the System" on Mercury Today (I thought this adventure always took place in the Simulant past but maybe they added a new one at some point.) and there was a Descendant Cyclops that you had to kill to get an arc charge whenever you failed to defend the objective. Unfortunately it looks like they just slapped the Descendant Vex Shader on a regular Cyclops rather than make a unique model.
