Colonel Clay was a military officer serving the Borginian Republic. In 2009 he was in charge of the country's weapons research facility on Ibis Island. He is presumed deceased after the Third Energy metastasis incident
As the Island's chief officer, Colonel Clay was heavily involved in Dr. Edward Kirk's Third Energy research. In the lead-up to their planned experiment in 2009, Clay met with Kirk repeatedly and also planned to chair a meeting in the strategy room the night before the final experiment.
After dinosaurs flooded the facility following the exchange it is unknown what happened to Clay, although it can be presumed that he was hunted down and eaten along with the majority of facility personnel.
