Voting is officially open in Round 1 of our TV Champion showdown.
You, the fans, have all the power as 16 shows battle it out for the title of Sci-Fi and Fantasy Champion.
From Sci-Fi titans like Doctor Who and Star Trek to Fantasy favourites such as Stranger Things and A Discovery of Witches (and let's not forget the superhero titles), it's time to rally the troops and get voting to put your favourite through to Round 2 – the Quarter-Final.
It's all to play for and remember, this vote is fandom v fandom, with unlimited votes meaning it really is the most passionate fans who emerge victorious. Think of it like a tug of war – stop voting, and your favourite show might fall behind.
Voting closes at 5pm BST today so you only have a matter of hours in which to ensure your pick stays top in their respective head-to-head.
With unlimited votes, you can refresh this page and vote again as many times as you want! So what are you waiting for?
First up it's Stranger Things v The Lazarus Project.
Next we have The Umbrella Academy v Moon Knight.
Then we have Foundation v A Discovery of Witches. Who will you put through to the Quarter-Final?
The Boys v Obi-Wan Kenobi should be an interesting showdown.
And the battle between two huge and passionate fandoms when it comes to this head-to-head: Doctor Who v Star Trek: Strange New Worlds.
Who will emerge victorious: Arcane or Outlander?
And who will you put through to the next round: Loki or Severance?
Finally, we have a big one: Ms. Marvel v The Witcher.
If you want the best chance of keeping your favourite in the running, you'll need to spread the word and get your fellow fans involved.
