You are going into battle against 100 soldiers on the back of a creature, What are you riding?....

[Calopolis]

One of the creatures from shadow of the colossus maybe

 

[RetroViruses]

A big daddy, since, seriously, he has a DRILL for an ARM

Alternatively, Gyarados...
although I don't know how that would work on land.

I'll take into account that Christianity holds a lot in sake of the values of society. So, I'll ride Jesus buuuuut not just ANY Jesus!

[Marv21]

A Balrog. A demon from the ancient world. Sure, it can fly, but why would it need to? Swords are of no use here, neither are bullets. Fly, you fools! (Note to self, wear fire-resistent clothes.)

(don't fight wizards with it, though)

Why get a Balrog when you could be on the back of Morgoth, basiclly the Tolkien version of Satan!

The Rainbow Serpent from Aboriginal mythology. Why? It is a giant snake that made all the rivers and canyons in the world. But more importantly, because it has pretty colours.

[lacktheknack]

A deathclaw.

I have an experimental MIRV.

Take one Blue Whale. Fit with tank treads and the ability to breath out of water. Set up a nice set of camping furniture near the blowhole. Sit back and listen to the screaming, whilst driving using a camera mounted on the whales nose.

Mmmmm, GTA: Worlds Largest Mammal
