Some things throughout media while they may have 0 to no relation with Warhammer
40k would strangely have no problem fitting into the universe with at most minor changes to their design.
One of which I've found is from strangely Courage the Cowardly Dog.
The Episode "The Tower of Dr. Zalost" has its title named tower.
The tower itself is a very standard "iconic" design that one would think of when one mentions "stone tower" in terms of a single tall stone tower with multiple windows/cannon ports in it sides. But what makes it fit into the world of
40k is its locomotion and sheer size...
It is mounted on a large wooden foundation platform bolted together with huge bolts that sits on 8 massive tread units (that dwarf Eustace's truck. They are at least as large as the NASA crawler treads if not larger), but it is assisted by 4 huge spindly
legs that stomp along as it moves.
By itself I keep seeing some utterly mad (aren't they all?) Chaos Sorcerer using it as a giant mobile fortress while standing at the top commanding the troops and demons below, while the cannons in the towers side rain hellfire on targets around him and warp energy crackles around the outside of the tower.
All it would need to be 1000% into
40k would be Chaos Symbols on the tower itself.
Can anyone else find Non-
40k things that would fit into
40k uncannily?
