Bowser Memory MLX

Bowser Memory MLX is an opponent in the Gauntlet in the game Mario & Luigi: Bowser's Inside Story, and has to be defeated in ten turns or less. Memory MLX is the only X boss (besides Bowser X) whose color scheme is not drastically altered from the original, instead appearing somewhat darker.

Bowser Memory MX
Bowser Memory MX has two attacks: Super Mushroom and Star. When using the Super Mushroom, Bowser Memory MX will grow and strike a series of red or green Brick Blocks above him. When the block is struck, the resulting debris will fall on the bro the color it pertains to. The debris can be defended against by using the brothers' Hammers. If hit, it may make a brother Dizzy. Bowser Memory MX will then shrink back to normal after being bitten by a Koopa Troopa Memory. To avoid this attack, the player needs to memorize the pattern of bricks bottom to top, and swing hammers in that order. The player can also avoid it by checking the way Bowser Memory MX jumps. If it is a regular jump, the debris will hit Mario, and if it is a spin jump, he will fling bricks at Luigi.

When using the Star, Bowser Memory MX will become invincible and dash straight towards one bro or other. The brothers can avoid this attack by jumping over him as he runs underneath, but if Mario or Luigi is attacked, he will be knocked off the screen and re-emerge when the invincibility wears off. However, a coin may occasionally appear, signaling a quick change of plans: if a coin appears above a Bro's head, Bowser Memory MX will jump and grab the coin (so the Bro. should refrain from jumping, unless the targeted Bro. jumps before Bowser Memory MX does, that coin will be added to the coin drop at the end of the fight), or a coin could appear in front of a Bro., signaling that Bowser Memory MX will grab the coin and attack the Bro. nearby.

Bowser Memory LX
Bowser Memory LX also has two attacks: being chased by a Boo Memory or throwing a Hammer Memory. When being chased by a Boo Memory, Bowser Memory LX will run and jump over a Bro; the Bro must then jump over or on the Boo Memory. Bowser Memory LX will often run in circles, alternating the bro he jumps over. He stops either after a few cycles or Boo Memory is defeated. In his other attack, Bowser Memory LX will wield a Hammer Memory and approach a bro, but will trip and toss the Hammer Memory through the air and directly at his target. The flying Hammer Memory can be defended against with the swing of a bro's own Hammer.

Additionally, Bowser Memory LX will take a step backwards when he is attacked. When he's attacked for a second time, he will run off of the screen, leaving Bowser Memory M to fight alone. Bowser Memory L will return after some time, but will retreat again when he's attacked two times. However, if Bowser Memory MX is knocked out when Memory LX runs away, he will revive Memory MX with 73 HP before leaving the battle.

Bowser Memory LX also will sometimes throw Mushrooms to Bowser Memory MX to recover 40 HP. He can also revive him via Memory 1-Up Mushrooms. Both entities have to be both knocked down in order to win the battle.

Trivia

 * When Memory MX uses a Super Mushroom, he grows, but is reverted when he is hit by a Koopa Troopa, referencing Super Mario Bros. and other platforming titles in the series.
 * When Bowser Memory MX becomes invincible, a remix of the Super Mario Bros. starman theme plays while he is invincible.
 * Bowser Memory LX's behavior during the battle is very similar to Luigi's personality.
 * Memory LX retreating away from the battle references Luigi's cowardice.
 * The Boo attack references Luigi's fear of ghosts. It also references the Shroob Chomp attack used by the Elder Princess Shroob from the previous game.
 * The Hammer attack references Luigi's clumsiness.
