Super Smash Bros. is an installement of the Super Smash Bros. series. The game itself is a reboot to the franchise.

Connection to Skullgirls
Marie appears as an alternate Final Boss in the Classic Mode and Shadows of Smash Mode, her boss stage is the Final Atrium.

As a boss, she fights as she did in her home series, when her life bar is drained to 2/3 of Health, she will transform for the first time; the second and last transformation will occur when her life bar is drained to 1/3 of Health. In her first form, she fights by spewing out an endless array of skulls that constantly fly in towards the player to intercept an attack/force blocking, sending a cluster of skulls towards the player at either a diagonal or horizontal angle depending on their current position, summoning a pile of skeletons from underneath the player's position to grapple their feet, causing slight scratch damage, then toss them across the stage for a moderate amount of damage, Creating a skeleton between her and the player that will disappear after a while, but will explode violently should anyone touch it and finally whacks the player character with her bone vacuum cleaner-scythe.

Her second form in this game changes its skin color to red, increasing the reference to the joke character Marie 300%. When transforming, she will emit a blue explosion which will seriously hurt the player should they be caught in it. The attack, however, has a clear warning to when it will happen: Marie will cease all of her attacks for a split second and blue smoke will start billowing from underneath her. The explosion will take about half a second to actually deal damage so a wary player can dodge it if timed correctly, and a lot less damage will be dealt if blocked. In her 2nd form, Marie will command the figure behind her to send a shadow out to attack the player from multiple directions, replaces her mass of skulls for a random skeletal minion that will come charging at the player diagonally or horizontally and create a variant of the skeletal minion where she brings in an undead Prohibition-era gangster to shoot at the player, pushing them back and damaging them if not blocked.

Design-wise, her third form remains the same from her home series. Here, Marie will explode in a blue explosion that can suck the player in and deals high damage. Like the 2nd form transition, she will cease all attacks before making this phase change, so stop hitting once she pauses and back away. If her health is drained before she can complete her transformation, she will die as soon as it finishes. In this form, she will use all of her attacks during this phase, but she will also become much more susceptible to damage. Blocking does not make a difference at this point due to her attacks dealing the same amount of damage, whether blocked or not.

When her Stamina drops to 0, Marie will explode, leaving the Skull Heart completely exposed.

The Fighters that are assigned to fight Marie in Classic Mode at the end of their round are Nin Yumizuka, Wario, Lucario, Meta Knight, Daisy, Min Min. Usually, Skull Heart Arrhythmia plays during the battle, but Terrormisu plays in Wario's Classic Mode, ARMS Grand Prix Final Battle plays in Min Min's Classic Mode and Final Battle plays during the Boss Rush.

As well, Filia appears as both an Assist Trophy and a Spirit while Peacock and Big Band are only Spirits.
