Elder Princess Shroob

Elder Princess Shroob appeared in 2005 video game called Mario & Luigi: Partners in Time. Elder Princess Shroob, referred to as Princess Shroob in-game, is a major antagonist and the penultimate boss of Mario & Luigi: Partners in Time. She is the leader of the Shroobs (her younger sister, Princess Shroob, is the second-in-command), an alien race that invaded the Mushroom Kingdom. When Princess Peach, Toadiko and Toadbert came to Peach's Castle of the past, they met the Shroobs. Elder Princess Shroob attempted to attack Peach; however, Peach used the power source of the Time Machine, the Cobalt Star, to trap the Elder Princess Shroob inside. Peach then shattered the Star into pieces; however, the younger Princess Shroob still was able to capture Peach and trap her in Shroob Castle.
