Oliver Toadstool

Oliver Toadstool is the stepson of Dragon Toadstool, and a secondary protaganist. He is a koopa with white hair, a purple shell and is the next in line to inherit one of the three Sage's Stones. His grandfather, Kuzzle is the only one of his family members left.

Before he met Dragon and Mario, Oliver was a nameless koopa whose family was killed by Bowser's father, Trowser because they refused to help build the portal to help him return home. Kuzzle, the current Sage had been taking care of him. After hearing about Dragon and Mario trying to go back The Mushroom Kingdom, he followed them. Dragon caught him, and after learning about him, decided to become his caretaker, naming him Oliver, after Oliver Queen. He helped Dragon defeat Trowser, exacting revenge and returning with Dragon to the castle. In the final battle, Oliver helped the others defeat the guards and foot soldiers throughout Bowser's Castle. He attended Dragon's coronation, as well as helped clean it up.

Oliver does not appear in the re-written version of 'The Lost Brother', implying he is no longer a canon character.
