Death Battle-(Fan)-Megas XLR vs. Optimus Prime!

When the world is under attack by the alien giants, whether they be organic or robotic, there will always be those iron giants to fight back!

A battle between two of the most badass bots alive!

Megas XLR, the ultimate battle mech! And Optimus Prime, leader of the Autobots!

I'm pitting these two ultimate robotic titans to see which one of them would win a Death Battle!

Bellow are the bios and action scenes to show what these two bots are perfectly capable of:

OPTIMUS PRIME:

Have fun!

Please answer in a way that doesn't sound too offensive, and don't start any arguments! This is for fun! Thanks for your cooperation!
