Maximillian Shreck is a powerful business mogul who is one of the main villains of Batman Returns. He serves as Selina Kyle's nasty boss and an unusual ally to the Penguin.

The businessman Max is well loved by the town and his son Chip, but nobody really knows his dark secrets which range from killing his best friend and flushing his body parts down the toilet, dumping toxic waste in the Gotham River, owning secret fire traps within Gotham City, murdering Selina Kyle, and presumably murdering his own wife.

Max appears to be giving and caring... when he's really aggressive and a big bully. Max wants to build a large power plant which he says will be good for the city when really it would eventually suck the power dry from Gotham, leaving a fortune of money in his legacy. But he ends up getting blackmailed by the Penguin (then later left) and Catwoman constantly trying to kill him. He's killed in the end when Catwoman shoves an electric plug into his mouth, frying him and leaving a frazzled corpse behind. Meaning that he eventually lost everything.

Despite being a horrible person, Max loves his son as he willingly took Chip's place when the Penguin came for him. It's likely Chip takes over his father's business.
