Some distance away (Away from Lucas in the same desert) Mario is out on a cliff looking at the Mushroom Kingdom when something odd appers…It's a portal! Someone is thrown out of it! Mario takes a stance but is confused and looks curious.
NEWCOMER: Magus
He gets up and takes out his scythe.
"Who are you?"
"It'sameMario!"
"Where am I?"
Mario takes out a map and points to the name of the kingdom
"Do you know your way around here?"
Mario nods
Magus gets up and dusts himself. His theme starts to play as you choose who to play as.
Mario and Magus go through a small canyon to get to the bridge of his castle and defeat some hammer brothers guarding the bridge and doors, they enter after defeating them.
Magus battles his way through Bowser's lair using his scythe, charged spells, flying and using his final smash Dark Matter!
After going through the lava filled room and getting past the fireballs instead of finding Bowser, they find Jr. with Peach's trophy. Mario gets mad and Magus and him make a pose as you choose who to play as to beat Jr.
After his near defeat, Jr. escapes with Peach into a portal made by his paintbrush. Magus and Mario follow.
