Jr. Troopa (or Master Jr. Troopa, as he calls himself) is a character and recurring boss in Paper Mario. He is a young Koopa who never left his egg after he was born. He lives near Goomba Village who enjoys picking on the other kids. He has his own piece of territory he calls "Jr. Troopa's Playground". Throughout the game, Jr. Troopa trails Mario and his allies during their adventure and returns in stronger form after each defeat. Mario battles him for a total of six times throughout the game.
Paper Mario series
Early in the game, Mario and Goompa travel to Jr. Troopa's playground to find the Goomba's missing Hammer and Goombaria's dolly. Eventually, they find the hammer and the doll and head back to Goomba Village. However, Jr. Troopa discovers Mario and Goompa are in his territory and challenges Mario to a fight. Mario defeats him and heads on his way.
After Mario saves the first Star Spirit from the Koopa Bros., Jr. Troopa ambushes him on his way back to Toad Town. During this fight, Jr. Troopa hides in his shell, raising his defense. However, Mario beats him once again and he flees.
Jr. Troopa appears once again in Forever Forest. He is so lost and scared he is initially glad to see Mario, but attacks him when he remembers they are enemies. Jr. Troopa's new ability is flight. Nevertheless, Mario beats Jr. Troopa yet again.
Still chasing Mario, Jr. Troopa trails him to Lavalava Island, swimming all the way across the ocean. However, just as Jr. Troopa arrives, Mario leaves on the back of a Whale, forcing Jr. Troopa to turn around and swim back across the ocean instead of flying. Jr. Troopa arrives at the harbor in Toad Town and challenges Mario. This time, Jr. Troopa places a spike on top of his head to go with his wings. However, his HP is lowered to twenty as a result of his continuous swimming.
Jr. Troopa appears once again in Shiver Snowfield, though Mario can learn from the penguins that they were talking about him making a ruckus. Jr. Troopa has learned some magic and uses a wand-like stick to create balls of damaging magic. After Mario defeats him, he gets frozen in a block of ice before he has time to recover.
Jr. Troopa makes his final appearance in Bowser's Castle, appearing just as Mario is preparing to face the Koopa Bros.. He defeats the Koopa Bros. himself and proceeds to challenge Mario. In this fight, Jr. Troopa starts in his normal form, later switches into his flying and spiked form, and finally goes back on the ground wielding his magic wand. After Mario defeats him, Jr. Troopa runs away, shouting that he will never give up.
Paper Mario: The Thousand-Year Door
Jr. Troopa makes an additional appearance in the Paper Mario arcs of Super Mario-Kun. He plays the same role as he does in the game by interfering with Mario's progress. As in the games, he uses various power-ups to aid him in the fight, but is always defeated in the end.
