Dr. Kate Travis was an old medical school professor of Dr. Neil Hamilton's, who went into the private sector to work on experimental growth treatments. Her serum, designed to combat growth deficiencies, was tested on a little boy named Bobby. It made Bobby grown into a belligerent giant. Travis contacted her old student Hamilton for help, asking him to find out what in Bobby's blood chemistry had caused the child to grow so big. Hamilton agreed, but unfortunately a cure was delayed by a series of circumstances involving giant lab rats. By the time Hamilton finally engineered the antidote, Bobby, now uncontrollably violent, killed Dr. Travis by breaking her neck.
Although called Dr. Travis in dialogue, she is inexplicably referred to as Dr. Treger in the end credits of Food of the Gods II.
