Normally, only Bowser can fight Dark Mechawful enemies in Mario & Luigi: Bowser's Inside Story. If Mario and Luigi are made to fight them, their attack becomes agonizingly slow, taking 4 and a half minutes to finish and give control back to the player.

"This could be the game glitching rather than something unfinished, possibly the game trying to use the head's star attack with the body attached."
More research is needed for the exacts
my 2 cents is that the attack has values corresponding to the speed stars fly by and coordinates where they should land, and it may be reading unintended values from the game's code
Makes me think they intended to have them fightable by the bros initially, but later scrapped it while they were adding this behaviour

even the ones that had specific mario and luigi graphics?
