Morton

"Me want to squish plumbers as much as you all do. Leave Morton some squishing too."

Morton Koopa Jr. is one of the Koopalings. He's a more brawn than brain compared to his other siblings. (Although Roy has a similar trait, he also uses his brain occassionally more than Morton) This can be further explained with his way of talking, as he talks with a more primeval tongue, and doesn't make proper sentences. But he's usually a lovable goof, who doesn't always use his brain, but he uses it whenever necessary. In the saga, he's voiced by Lani Minella.

Lore
Morton Koopa Jr. is a member of the Koopalings. Not much is known about his parents, but his grandfather Morton Koopa Sr. was a renowned member of Koopa Clan, as he was the advisor of Bowser's father, Bowsedgar the Daring. After his grandfather passed away, his father Morton Koopa took up the task, only to be murdered in an outbreak, attempting to protect Bowsedgar from the rebels. Morton's mother also died giving birth to his son, making him an orphan, unfortunately.

When Bowsedgar's son Bowser came to the throne, he took Morton from an orphanage, whom he was there for some time. Morton's natural strength deriving from his father gave Bowser a great idea of Morton's future: A powerful soldier and a commander someday. So, he tried his best to teach Morton how to lead an army, also giving him tools to make his physical strength improve. Everything was going well, but one day, Morton had an accident. He fell from a high place and hit his head quite hard. Luckily, he wasn't gravely injured but his brain had a slight damage, causing a change in his speaking.

A few years later, as Morton had a surgery for fixing his damaged skull. It was successful, but his brain damage couldn't be reverted, luckily it wasn't severe. This didn't affect his future however, as he could speak not so well, but enough to be understood easily. When he came of a proper age, he was sent alongside his siblings for a mission: To take over the 7 kingdoms around Mushroom World: He was assigned to the Desert Land, giving the denizens there fear. But his reign of terror was over, by the hands of two heroes.

His later placements weren't helping his reputation either, but he had given some challenge to his adversaries, as he was growing stronger, he was being more formidable. He mainly took part as a powerhouse of the team, using more power in his attacks, rendering his enemies unable to move occassionally. Despite his attempts, he wasn't successful.

But a future awaits Morton, where he can someday achieve what was assigned to him. Despite his hardships mentally, he has the great capacity as a strong leader.
