As the head nurse, she cares for anyone who is injured, both physically and mentally. She wants to help Caelan get over his grief and guilt, but he always shuts her out.

He saw promise in the young man when he came to his palace, a place where legend said only those with the fire of King Koopa in their hearts could set foot.

Training with him can be a little unusual though, as he often bursts out in fits of laughter, which cause him to revert to his normal form. Even though he wants to help Bando as a spy, he knows that he's not able to keep a disguise long enough without laughing.

She decided she can use her magic to help the injured soldiers, which is what she seems to be best at.
BowserBowser normally could care less about what happens to Mario, and he claims the only reason he's supporting the resistance is so the Dark Soul Ztar won't take over his kingdom, although he secretly doesn't want his longtime rival being evil, He feels as though Caelan is hiding something from him and Peach, but can't be sure what.
MarioAfter being freed, Mario is back to his cheery old self. He's determined to save his brother and stop the Dark Soul Ztar from painting the world black. He feels odd about Caelan, as though he's seen him somewhere before, but can't be sure.
The Dark Soul ZtarThe Dark Soul Ztar is an Artificial Star that was activated approximately three years ago by Caelan in a last ditch effort to bring his parents back to life. It's original function was to collect energy from the seven Rainbow Paint Stars and repaint dead creatures. However, Caelan forgot to take into account that when the seven colors of the rainbow mix, they create black. Upon activation, the energies mixed and created Black Paint Energy, which overloaded the machine's circuits and turned it into the Dark Soul Ztar.

Shadow LuigiShadow Luigi, like Shadow Mario is the result of the Dark Soul Ztar's influence on innocent Luigi's mind. Unlike his normal counterpart, Shadow Luigi is not easily frightened. For some odd reason, he likes to pretend he is a super villain called The Green Thunder, and often says "The Green Thunder strikes alongside The Red Lightning!" upon entering with Shadow Mario, much to his brother's annoyance.
