Cat Knight AI Video Generator – Turn Your Cat Into a Viral Kitten Knight

It's the best-known version of the cat knight trend. The clip opens on a tiny kitten in silver armor with a pink bow, holding a sword in front of its face while the wind whips its cape. Then the camera pulls back and a giant masked man with an enormous greatsword steps in beside it and takes the same pose. That giant is Derek Mercer, a fitness character who only exists in AI videos, and the clip was his team-up with sickmanai, the account behind the knight kitten. People share it as a promise between friends: you may be the small one, but you never go into battle alone.

On this page it takes three steps and no prompt. 1) Upload the knight as Photo 1: your cat, another pet or a child, sharp and in good light, with the face clearly visible. 2) Upload the giant as Photo 2 if you want one: a clear photo of you, a friend or anyone else who stands guard, ideally showing their whole upper body. Leave it empty and the masked giant from the original stays. 3) Choose 480p, 720p or 1080p and hit Generate Video in the generator above. First the two photos are drawn into the final wide shot so the sizes, the armor and the sword match the meme, then the whole 10-second clip is replayed with your cast and the original audio is laid under it. Your video lands in My Creations, usually within about 10 minutes.

In the cat knight AI video generator above, upload one photo of your cat as Photo 1 and leave Photo 2 empty. That gives you the cat knight video exactly as it went viral: your cat in the armor, the pink bow and the white cape, holding its sword in the wind, then the camera pulls back to the masked giant standing beside it, all in one 10-second take with the original audio.

There's no single official app. The original clip and its creator's tools haven't been published, and most remakes going around come from general AI tools: an image model to draw the armored cat, then an image-to-video app such as Kling, Dreamina, Google Flow or Higgsfield to animate it, often with a lot of re-rolls. That route gives you the most freedom but the most work, and the camera pull-back and the giant's entrance rarely come out the same way twice. This cat knight AI video generator is a dedicated template instead: it's built on the real clip, so the close-up, the reveal and the wide shot follow the original, and you only add one or two photos. It runs in the browser on a phone or a computer, with nothing to install.

The hard part of the kitten and giant shot is the size contrast: the knight has to stay tiny next to the giant from the first frame to the last, in the same pose and in the same wind. Text prompts tend to lose it, either making the cat too big or turning it into a small person. Here the two photos are first placed into a still of the original wide shot, with the knight at the giant's feet, no taller than the middle of his shin. That still then guides the video, so the knight and the giant keep their sizes through the whole pull-back and never swap or blend. Photo 1 is always the knight and Photo 2 is always the giant.

The muscular giant in the meme is Derek Mercer, an AI character with his own following, and people who make characters like him in tools such as Higgsfield usually design the character first (face, build, outfit and accessories), save it as a reusable character or face, build a character sheet from the front, side and full body, and then animate it with image-to-video or a motion reference. You don't need any of that here. Leave Photo 2 empty and the masked, muscular giant from the original clip stays in your video, greatsword and all. Add a photo of a person and they take his place with their own face and build: the scene makes them a giant by scale, not by adding muscles.

Yes, this cat knight AI video generator is one. Some template sites split the trend into two: a one-photo knight cat template and a separate two-photo version with the giant. Here both are the same template. Upload just your cat and you get the knight cat meme with the original masked giant; add a second photo and that person becomes the giant standing guard. There's no prompt to write or copy, and the 10-second clip comes back with the original audio already on it.

Upload a clear photo of your cat as Photo 1, add a photo of yourself or a friend as Photo 2 if you want to play the giant, pick a resolution and generate. The template recreates the viral knight cat video beat for beat: the close-up of the brave little knight, the boot stepping into the frame, the camera tilting up to the giant and the final wide shot of the two of them side by side in the fog. Because it follows the original clip rather than a text prompt, the timing, the camera and the wind match the meme every time.

Upload a selfie as Photo 2 and you become the giant: you replace the masked man and step into the frame beside the little knight, holding the enormous greatsword upright with both hands. You keep your own face, hair, build and the outfit you wear in the photo, without the balaclava. Put your cat in Photo 1 and the two of you stand guard together in the fog. A front-facing photo in good light that shows your face, shoulders and chest works best.

Upload a photo of your cat as Photo 1. The best photos show its face straight on or at a slight angle, in daylight and in focus, with nothing covering its eyes, and only your cat in the picture: no one holding it and no second pet. Its own fur, eye color and markings carry through to the armored knight, so a tabby stays a tabby and a black cat stays black, and it stands upright gripping the sword with real paws, never human hands. Add a photo of yourself as Photo 2 if you want to be the giant beside it.

Yes, that's what the trend is about. Put your cat in Photo 1 and your friend in Photo 2, and they become the giant standing guard beside your little knight, in their own face and build. Or flip it and use their cat as the knight with you as the giant. Send it to them with "Remember your gym bro" as the caption. Only use photos of friends who are happy to be in it.

Use Photo 2. Whoever is in it replaces the masked giant from the original: their face, hair, skin tone and build stay their own, they wear the outfit from the photo, unmasked, and they hold the huge greatsword upright with a serious face, towering over the knight at their feet. You don't need to be muscular or tall: the scene makes you a giant by scale. For the sharpest face, use a well-lit, front-facing photo that shows your upper body rather than a tight crop.

Yes, and it makes a sweet couple version. Put your cat (or the pet you share) in Photo 1 and your boyfriend or girlfriend in Photo 2, and they become the giant standing guard over your little knight. It works as a "you protect me" post, an anniversary surprise or a reply to "me trying to handle things maturely". Use a photo of your partner alone, not a picture of the two of you together, so the AI knows exactly who the giant is.

Yes. The first upload card takes the little knight and can't be left empty; the second takes the giant and can. With both, the two of them star in the video together; with Photo 1 only, the masked, muscular giant from the original stays. Either way it's the same 10-second clip at the same price, and each photo should show just one subject.

No. Cats are the classic, but other pets work too: yours stands upright in the armor holding the sword with real paws, keeping its own face and fur. You can also put a child in the armor for a parent-and-kid version, with the parent as the giant in Photo 2. A child keeps their own face and natural proportions, wears the armor and cape without the pink bow and stays small beside the giant. Use one subject per photo: no one holding a pet and no group shots, so the AI knows exactly who the knight is.

It's 10 seconds, the whole clip from the first close-up to the final wide shot, in 4:3 like the original, with the original audio included. The 4:3 frame keeps both the giant and the knight in the shot; on TikTok or Reels it plays with a little space above and below, the same way the original was shared.

A 480p cat knight video is 500 credits while the trend is hot (the usual price is 700). 720p costs 1,000 credits and 1080p costs 2,100. One price covers everything: the knight, the giant, the full 10-second take and the original audio, and adding the second photo doesn't cost extra. A run that fails is refunded in full.

Signing up gives you some credits to start with, and checking in each day tops them up, so you can save toward a 480p knight without buying a plan. If your best friend's birthday is tomorrow and you can't wait, the trial pack covers one 480p video, and a failed run refunds every credit.

Yes. You get a clean MP4 with nothing stamped on it, so your cat's brave little face in the opening close-up and the giant's entrance stay uncovered. Save it to your phone and post it to Reels, TikTok or your group chat as it is.

Swap one photo at a time so you can tell what fixed it. If your cat's face or markings drift, use a sharper photo taken in daylight with the face toward the camera and nothing in front of it; a blurry or very dark photo gives the AI too little to copy. If the giant's face changes, use a front-facing photo with the face well lit, and one that shows the shoulders and chest rather than a tight crop. Each generation is a new take, so the same photos can come out differently on a second try.
