I like the Mario & Luigi Final Boss theme from Brothership which a lot of people hate, but I like it cus it fits the character who is an insane maniac who has canonically destroyed multiple worlds without giving a F*** about everyone slowly dying.
Mario & Luigi(from the M&L RPG): Has move that stops time, has beaten over 98,000,000 of Bowser's minions, Can freeze the sun and melt glaciers, can combine said ability of freezing suns and melting glaciers to make explosion.
