|“You will rue the day you ruffians stormed our club.”|
|— Underhill to a Maaray Guard in "Riddle of the Sphinx"|
Underhill is an archaeologist and a member of the Explorers Club.
Later, he was in a meeting along with Shippelton and Smythe before being interrupted by Lloyd, Nya, and Zane. Once Shippelton realized the ninja were stealing an artifact, he called security which caused the ninja to flee to one of the rooms.
Once the ninja escaped The Explorers Club, the building is left in disarray. When Smythe was talking to Shippelton on who to blame, they were under attack by Venomasicus Tigrus and began to run.
He was at Nya's funeral.
