NPC Energy is the breakout viral mack style of 2026 — the stiff, robotic, glitchy "two video-game NPCs colliding for a kiss" aesthetic. It's the most-shared style on TikTok within the AI kissing video category and one of the styles that got Let's Mack on the For You page in the first place. Ready in 30–60 seconds.
What NPC Energy looks like
The NPC Energy style produces a 3–5 second clip with these visual signatures:
- Motion: Stiff, robotic head movement. T-pose-adjacent posture before the kiss. The lean-in is angular and lurchy, not smooth.
- Facial expressions: Blank or slightly off — the empty-stare look NPCs have when their AI scripts haven't loaded.
- Glitches: Subtle visual artifacts mimicking video-game render glitches: brief polygon flickers, slight model-clipping, occasional asset-pop.
- Lighting: Flat video-game lighting with slight ambient occlusion — looks like a cutscene from a mid-budget RPG.
- Rhythm: Output is silent (Let's Mack videos have no audio) but the visual rhythm matches "low-frame-rate cutscene awkwardness."
Why NPC Energy went viral
NPC Energy works on TikTok for two reasons. First, the visual is instantly funny — the contrast between two real photos and the deeply unromantic NPC behavior creates the comedic tension. Second, NPC Energy is a recognized cultural reference (the NPC TikTok wave from 2023–2024 trained the audience on what to expect), so the style reads at a glance even on auto-scroll.
When to use NPC Energy
- Group-chat humor. Drop an NPC Energy mack of two friends in the chat — the awkwardness is always funnier than a sincere kiss video would be.
- Coworker / classmate prank content. Pair two coworkers who would react well to seeing themselves NPC-kissing.
- Viral TikToks. NPC Energy is the highest-engagement style on TikTok for the AI kiss category. Trending audio: NPC-related sounds, "literally just an NPC" voice memos, video-game OST snippets.
- Reaction-bait crush content. Send an NPC Energy mack to your crush as a deniable "haha look at this glitchy AI" — funnier and lower-stakes than a Movie Kiss.
- Friend ship-content where sincerity would be too much. NPC Energy lets you ship friends without committing to seriousness.
Best photos for NPC Energy
NPC Energy works on a wider input range than the romantic styles because the glitchy aesthetic masks input quality issues. The funnier the input mismatch, the better the output.
- Casual selfies. The contrast between a normal selfie and the NPC behavior is the joke.
- Group-chat-typical photos. The kind of phone-flash photo that ends up in a group chat anyway.
- Two photos that look unrelated. Two-Photo Mode + NPC Energy is hilarious for pairings that don't make sense.
- Workplace / classroom photos. Office party / school portrait + NPC Energy = perfect.
Two-Photo Mode with NPC Energy
Two-Photo Mode + NPC Energy is one of the highest-comedic-leverage Let's Mack workflows. Workflows:
- Two coworkers who didn't know they were being paired up.
- Two friends who hate-flirt in real life — NPC Energy lampoons the dynamic.
- Crush + you with NPC Energy as the deniable cover.
- Two streamers / public figures who would react well in their next stream.
NPC Energy for TikTok
NPC Energy outputs do best on TikTok with audio overlays in this priority:
- NPC TikTok-wave audio. Trending NPC voice memos and gestures audio.
- Video-game OST snippets. Skyrim / Witcher / Fallout cutscene audio works well.
- "Literally just an NPC" voiceovers.
- Low-bitrate / 8-bit audio to lean into the video-game vibe.
Captions: "the NPC arc continues," "POV: the AI is unwell," "ok but unless?" with NPC framing, "tell me you're an NPC without telling me." Post 7–11pm in your timezone — NPC Energy peaks during evening doomscroll hours.

What does the NPC Energy style look like?
NPC Energy produces a 3–5 second clip with stiff robotic head movement, T-pose-adjacent posture, blank facial expressions, subtle visual glitches (polygon flickers, model clipping, asset-pop), and flat video-game lighting.

Why is NPC Energy popular on TikTok?
Two reasons. First, the visual contrast between real photos and deeply unromantic NPC behavior is instantly funny. Second, NPC Energy references the 2023–2024 NPC TikTok wave so the audience already understands the punchline at a glance — works on auto-scroll.
When should I use NPC Energy over other styles?
Use NPC Energy for group-chat humor, coworker / classmate prank content, viral TikTok bait, reaction-bait crush content (deniable "haha look at this glitchy AI" cover), and friend-ship content where sincerity would be too much. Skip it for sincere romantic content — pick Movie Kiss, Rain Kiss, or Classic instead.
Does NPC Energy work with Two-Photo Mode?
Yes — Two-Photo Mode + NPC Energy is one of the highest-comedic-leverage Let's Mack workflows. Pair two coworkers, two friends, two streamers, or crush + you with NPC Energy as the cover. The pairing mismatch + glitch aesthetic = comedic peak.
What audio works best for NPC Energy on TikTok?
NPC TikTok-wave audio (NPC voice memos, "literally just an NPC" sounds), video-game OST snippets (Skyrim / Witcher / Fallout), and low-bitrate 8-bit audio. Pair with captions like "the NPC arc continues" or "POV: the AI is unwell." Post 7–11pm in your timezone for best engagement.
