Dr. Mario
From Yb Timeline
History
Dr. Mario arrived at the YB HQ just as they had finished a mission with several injured. He was quickly hired as they needed a doctor and he began work. Work being mostly watching soap operas. Around this time Phazon began to appear on Star World, mutating some creatures. Koop detected one such creature lurking about at Yoshi's Island, and so they went there to fight it with some prototype weapons he had made.
The creature turned out to be a monstrous, mutated shy guy. A meteorite made of phazon fell out of the sky and hit the shy guy, mutating it further and increasing its size to thirty feet tall. They were able to incapacitate the shy guy, though, but Dr. Mario and Luigi were accidentally left behind. They were picked up by Danny while heading to a party hosted by Princess Peach in honor of the YB.
The party was interrupted by Metal Top, who used a speech Peach gave to awaken the Beanstar. It then raised Peach's Castle into the sky with a giant version of itself and used the Beanstar to become invincible and blast the YB out of the castle. To defeat Metal Top, the YBs traveled to Star Haven to get the Star Rod, but found it had been shattered. This sent them on a journey to rebuild it from the shattered fragments. Eventually they rebuilt the Star Rod and used it to engage Metal Top in a wish battle, finally destroying it.
Dr. Mario later joined them in investigating a Space Pirate base on Yoshi's Island, though as usual he lagged behind. While trying to catch up with some others they overheard some loud roaring and something crashed through the cavern wall, a giant phazon-mutated Wayoshi. The damage from this colossus caused the base to collapse and they had to escape. Later all the phazon culminated in infected water that evaporated into phazon clouds that then rained phazon. The resulting rain infected a nearby forest that began to attack the HQ, forcing the YBs to flee, but mutated paratroopas showed up and attacked them.
About this time Anubis contacted them and led them to a large crater where the phazon was originating from. They arrived, but Dr. Mario stayed behind in a ship because, really, he cures fever and chills, not phazon. The other YBs (primarily Anubis) then destroyed the source of phazon, Sango, the Titan of Thunder, and they returned to the HQ. After this Dr. Mario's past began to catch up to him, as ghosts began to haunt the HQ, claiming that Dr. Mario had killed them, something he denied. After the YB got the ghost to go away, Dr. Mario decided to leave. The rest of the story didn't get done.
