“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.

History

The Explorers Club

At The Explorers Club, he and Smythe were listening to a presentation by Shippelton on a recent exploration he had.

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.

Riddle of the Sphinx

Underhill is watching Clutch Powers' presentation on how he "obtained" the Storm Amulet. He later fights off some Merlopians.

The Turn of the Tide

He was at Nya's funeral.
