Rick And Morty: 10 Worst Things Morty Has Done

Here's a great piece of advice; if your grandad - who's an expert in all things space - tells you to leave something be, then it's probably best to take his advice, even if it feels wrong. Unfortunately, Morty got first-hand experience with that in this episode, where he technically tried to do the right thing but inadvertently brought Earth, his family and time itself to its knees.

In season four's "Rattlestar Ricklactica", Rick and Morty are mulling around in space - as they are want to do - and Morty gets bitten by a space snake. Instead of leaving it at the behest of Rick, he buys a replacement snake and sends it to the snake planet that the original creature came from. But, this would end up being a grave mistake as he accidentally created an unprecedented conflict.

The snake civilisation ended up creating a time machine that sent an assassin back to kill Morty before he alters the course of their history. But, as time travel would do, the number of travellers piled up, creating a perpetual time travel war. Well done Morty, hope you're proud of yourself.
