[[WMG:Max is [[ShockAndAwe electrokinetic]].]]
When Darla signals for visual representation that she's having an idea after her song-and-dance number "Big And Loud", Max promptly holds an ordinary [[IdeaBulb lightbulb]] over her head. The bulb (connected to nothing but his gloved fingers) ''lights.''
Later in the film, Max incapacitates Pudge the penguin by seizing him and rubbing him fiercely on his head, then sticking him to a metal beam with the static electricity. Normally, in cartoons, this works whenever both objects are suitably fuzzy; say, a FunnyAfro, or a cat on a shag rug. But Max is ''[[http://i9.photobucket.com/albums/a80/Javer80/Comics/MaxHeadMS1.jpg bald]]''. Both events are explained if it is assumed that Max can generate and control electricity. In a very cartoony, physics-bending way, of course.
[[WMG: Darla Dimple isn't actually a child.]]
She only looks like one.
Note her resemblance to [[WesternAnimation/BatmanTheAnimatedSeries Baby Doll]], who is an adult actress with a rare condition that makes her look like a child even when she's an adult. She seems too smart, too vindictive to be a kid. (Or maybe this troper just can't handle hating a little girl. It makes her feel horrible.)
[[WMG: Max is Darla's father]]
She demands he call her Miss and be her bodyguard because...she's [[SpoiledBrat Darla]].
** This makes more sense if he's meant to be a ShoutOut to Max von Mayerling from SunsetBoulevard: secretly a family member who's been demoted to faithful servant.
[[WMG: Darla had Max kill her parents.]]
She used the insurance money to rise to stardom.
[[WMG: Max is a shaved gorilla]]
He could only get work if he looked more human.
[[WMG: Max and Film/KingKong are related but don't get along]]
It's already established that King Kong exists in the story and is an actor. Based on the above theory about Max being a shaved gorila, it's possible that Kong and Max are related and Kong resents Max for abandoning their fellow animals for a better or at least steadier job than theirs.
[[WMG: Darla's parents were hunters.]]
Based on one of the above theories, they took a baby gorila from Africa after killing the gorilla's parents, named him Max and conditioned him to serve Darla and pretend he's a human. It's possible Darla herself doesn't know Max isn't a real human.
[[WMG: Darla's parents don't love her]]
They only care about the money she used to bring and were happy to leave Max in charge of her upbringing. Once she destroyed her reputation, they fled the country and took as much Money as they could while Darla had to sell her mansion and get a job to pay her debts.
