Private Koopa

"Sorry if I'm short with you. I don't wanna freak you out... but I'm sorta freaking out."

- Private Koopa

Private Koopa is a green shelled Koopa Troopa and a member of the Koopa Troop, meaning he is a minion of King Bowser Koopa.

In Super Paper Mario, Private Koopa was seemingly among the Koopa Troop members organized by Bowser for his raid on Princess Peach's Castle; this meeting of the Koopa Troop was subsequently interrupted by the appearance of Mario, Luigi and later, Count Bleck. After knocking Mario unconscious, Count Bleck proceeded to transport everyone present at Bowser's meeting to Bowser and Princess Peach's "wedding".

Among the cheering crowd of captive wedding goers, Private Koopa bore witness to Count Bleck and Nastasia's marrying of Bowser and Princess Peach and the summoning of the Chaos Heart. Private Koopa was subsequently transported into Count Bleck's realm after witnessing all these events, where he and his unnamed, Hammer Bro. Captain wandered around aimlessly.

While traveling through Count Bleck's realm, Private Koopa and his Hammer Bro. captain found an unconscious Princess Peach, who they awoke; after Princess Peach was awakened, the Hammer Bro. left Private Koopa to guard her while he went to search for what remained of the Koopa Troopa, most of whom had been brainwashed by Nastasia.

Unfortunately, after some traveling with Princess Peach, Private Koopa and Princess Peach were found by Nastasia, who proceeded to brainwash Private Koopa, making him a mindless slave of Count Bleck.
