Core-chan, also known as Reactor-chan, is an anime-style anthropomorphic drawing of the exposed reactor four core from HBO's 2019 Chernobyl miniseries. 4chan's /tv/ board turned a still from the show into a glowing, smoke-bodied girl within days of the premiere, and by May 15 the character had a dedicated Rule 34 gallery.

Overview

Fan artists usually draw her as a tall nude figure with ash-grey or black skin, molten orange cracks across her chest, and plumes of radioactive smoke rising from her hair5. Earliest 4chan edits worked bottom-up, starting from the raw screenshot of the burning core and pasting anime eyes over the glow4. Full gijinka illustrations came next and replaced the photo entirely, with the reactor fire shown as light through her ribs and neck6. Tone across the art skews horny and ominous at the same time, playing the gijinka suffix for jokes against the backdrop of the real 1986 disaster7.

Date

2019

HBO aired the first episode of Chernobyl, titled "1:23:45," on May 6, 20191. In that episode, the camera lingered on the destroyed reactor four, glowing red inside the open pit8. On May 7, an anonymous user on 4chan's /tv/ board asked whether any anthropomorphic fan art of the reactor existed yet2. One day later, another anon reposted the core still with the caption "this is core-chan"3, and a third user edited the same screenshot to add anime eyes on top of the fire4.

How It Spread

Full illustrated gijinka art appeared on May 11, 2019, when an anonymous /tv/ user shared a hand-drawn depiction of the character6. More drawings in the same style showed up on /tv/ across the following days5. Starting May 15, 2019, Rule 34 user BobMarcel began uploading a collection of Core-chan images to paheal.net7, which became the main off-site archive for the character.

How to Use This Meme

Artists typically start with her canonical features (ash-grey skin, nuclear-green or orange inner glow, smoke pouring off her hair) and place her into gijinka scenes with elements from the disaster, like a reactor lid or a hazmat crew6. Posts often lean NSFW, since the lineage runs through /tv/ and paheal, not general anime fan communities7.
