Lag Kraken
A grumpy creature that lives in your internet. It pops out during online games and yanks you back to the start like you're a clumsy kid who tripped over their own feet.
I had the best score, then the Lag Kraken came out and I was back at the beginning.
I was in the lead, then the Lag Kraken hit me and I got teleported to the spawn.
I was about to win, then the Lag Kraken showed up and I had to start again.
