I Guess We Can Get Started.
Eh?

The Teal Plumber On The Left?
This Is Kai Mon.
He Is A 16 Year Old Teenager Who Really Loves Action And Fights.
And Loves His Family.
If You See Him Sit Like This, You're Done.
Dead To Rights.

The Right One Is Rose Mon.
The Brown/Damascene Plumber.
She Is Kinda Like Her Older Brother, Mario Mon, But Almost.
She Is 18 Years Old.
Despite Her Attitude, She Still Has Care For Her Family.

And The Middle One...
Finally...
His Name Is Marlin Mon.
(Or Just Simply Call Him Marlon)
A Sweet, Lovely Boy.
He Is A 8 Years Old Kid.
Luigi Mon And Melissa Wouldn't Not Allow Marlin Mon To Fight.
Or Train As They Are Trying To Take Care Of Him Whenever Marlin Mon Visits Luigi Mon's House.
But Mario Mon & Kai Mon
They Would Try To Train Him.
They Need Him To Get Stronger And Better.
So Whenever He Grows Up.
He'll Have To Fight On His Own, Or Other People On His Side.
