I’m a bit confused as to why he wouldn’t turn to them sooner. He clearly has worked with different Mauler Twins who seem equally as villainous, so why not go for the pair that he would’ve known best, considering he knows for sure that they’re renowned for their intellect?
Does it matter? He did go for the pair he knew best, at the end sure, but he needed that many Maulers to fix the machine.
