Mechawful

Mechawfuls are large robots based on Fawful, first appearing in Mario & Luigi: Bowser's Inside Story and later in Mario & Luigi: Superstar Saga + Bowser's Minions.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
In Mario & Luigi: Bowser's Inside Story, Mechawfuls are found in Peach's Castle Garden. They can attack by flying towards one of the Mario Bros. and attempt to hit him with its fist. The player must hammer the Mechawful multiple times to prevent damage. An alternate attack used by the Mechawful is to fall from the air and land on the player. It is possible to predict which attack the Mechawful will use by watching its movement on the top screen of the game. If the Mechawful flies out of view, then it is preparing to land on its target. The dust marks which appear will also reveal which bro. is the target of the Mechawful's attack. Mario and Luigi must hit it with a hammer to deflect it. This will send the Mechawful flying towards and damaging other enemies in the match, if any.

As Bowser, the player must quickly duck to avoid the Mechawful's attack. Alternatively, the Mechawful will rise to the top screen and land in front of Mario, Luigi, or Bowser. Failure to attack it immediately will cause the Mechawful to punch its target. Immediately after landing, the bros. must hit it with a hammer, or Bowser must punch it, to trigger a roulette-type action. Once the roulette is activated, the Mechawful's chest will light up and eyes will cycle through the colors yellow, blue, and red. Attacking it again will cause the roulette to stop.
 * If blue, the Mechawful returns to its place without attacking.
 * If yellow, the Mechawful will use a counterattack.
 * If red, the Mechawful will self-destruct, harming the player. It will only award Experience and Coins for defeating the head of the robot (not the rest of the body) at the end of the battle. It may also cause the player to become dizzy.

When defeated, the head detaches from the body and will either fly away, attack, or summon a new body on the next turn. Bowser can inhale the head, preventing the Mechawful from reassembling its body. Mario and Luigi can then fight the head of the Mechawful inside Bowser. Occasionally, the head is destroyed with the body when the Mechawful has self-destructed, or when it is destroyed as a result of a counter-attack.

Like most other large enemies, Bowser can use the Vacuum Block to inhale a Blitty from Mechawfuls. Yellow Mechawfuls appear in the battle against Super Peach's Castle of Fury, and a dark blue variant called the Dark Mechawful can be battled by Bowser.

In the remake, the Mechawful's roulette light attack is removed, and replaced with an attack that involves a shield. The Mechawful will generate a shield which must be punched (or hammered) four times to break, then they can attack the Mechawful to push it back. They also no longer try to land on Mario and Luigi in the overworld. Mechawfuls are one of the few enemies to not appear in Bowser Jr.'s Journey.

Mario & Luigi: Superstar Saga + Bowser's Minions
Although they do not appear in the original Mario & Luigi: Superstar Saga, Mechawfuls, renamed Mecha-Fawfuls, are added in its Nintendo 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, where they are shown as the ones responsible for the initial destruction of Beanbean Castle Town, and appear solely in the new mode, Minion Quest: The Search for Bowser. Unlike the Mechawfuls of Mario & Luigi: Bowser's Inside Story, these Mecha-Fawfuls have a patchwork-like design and crooked antennae. There is no generic type of Mecha-Fawful, with them instead coming in three variants:
 * Mecha-Fawful X, which have wrecking ball hands and wheels akin to Dark Mechawfuls
 * Mecha-Fawful Y, which is a Mechawful Head with arms akin to Dark Mechawful Heads
 * Mecha-Fawful Z, which has legs like the original Mechawful, while their arms have elbows and end in Piranha Plant-like jaws.

All three are weak against Broozer and Starlow.
