I recommend cut from Film and Literature folders:

"The Thirteenth Warrior inserts a Real Life Arab diplomat into Viking country to fight cannibalistic Neanderthals in a story ripped off from Beowulf."

"Cannibal Robots" are a contradiction as are "Time travelling Neanderthals." "Cannibal Neanderthals" are NOT a contradiction.

The enemy are just cannibals. The Neanderthal Rubber Forehead Alien motif is just a Hat.

I'm certain that this XKCD comic relates to this trope, but I'm not exactly sure what category of relations it falls into.

A Ninja Pirate Zombie Robot is a ridiculous idea. Robots can't be zombies, and pirates would make awful ninja.

Now a Robot Zombie Pirate Ninja, that would be awesome.*

^{I'm thinking of course of a ninja-turned-pirate brought back to unlife with extensive cybernetics.}

One of my ancestors was a pirate, I know karate, my mom and dad refer to themselves as a ninja and a pirate respectively, and I call myself the Tippy Toe Zombie, all I need is to be a robot.

I am the Tippy Toe Zombie I like to Limbo Often I fall on people's heads
