“Sassy,” a pirate played by Sophie Jacobs, panics yesterday as she is surrounded by “Snol” and the winged “Apocalypse Bot,” robots played by Jon Axell and Justin Tanner. While Sassy ultimately met her demise by Snol’s sword, The Collective, the campus improv group that orchestrates the battle in the Quad each spring, believes that when robots, pirates and ninjas battle, everybody wins.
