Eviledon is described across multiple fan-maintained Brainrot and Roblox guide sites as a Secret-rarity character from Steal a Brainrot, the Roblox game created by Sammy, also known as SpyderSammy. The character is usually treated as an aquatic shark variant tied to the broader Italian Brainrot meme ecosystem rather than as a standalone meme with a well-documented original post.
In plain visual terms, Eviledon is almost always presented as a dark red or crimson reworking of Tralaledon: a shark or megalodon-like figure with a more demonic silhouette, curled horns, black striping on the horns, and sharper fang-like teeth. Several sources explicitly frame it as a devilish or Halloween-themed redesign of Tralaledon.
The most stable gameplay details are fairly consistent. Community wiki and guide pages list Eviledon as a Secret Brainrot with an income of about $31.5 million per second and a cost usually shown as either $3.8 billion or $3.85 billion.
That small price mismatch appears to be a rounding or documentation difference between sites rather than evidence of two separate versions. It is repeatedly associated with the Witch Fuse Halloween event in Steal a Brainrot, and several pages call it one of the rarer Witch Fuse results, with one fan wiki describing it as the third rarest outcome behind Headless Horseman and Spooky and Pumpky.
Later community documentation also places Eviledon in the Aquatic Index and says it could be obtained outside Halloween through the Fishing Event, while stealing it from another player's base is also listed because stealing is a core mechanic of the game. The lore attached to Eviledon is much stranger and much less clearly official, but it is repeated often enough to summarize cautiously.
Fan lyric pages say Eviledon is the lost brother of Tralaledon and was separated from him during a tsunami in the Indian Ocean. Those same pages describe him as traumatized by that event and as someone who came to see danger as something positive.
This backstory is paired with warning-heavy narration that paints him as monstrous and unnatural. Brainrot.jp simplifies the same idea into a shorter character note, saying he resembles Tralaledon but is red and horned, and that he lost his brother Tralaledon in the Indian Ocean tsunami.
Because these details come from fan-facing lyric and character pages rather than a clearly archived primary creator post, they are best treated as the commonly repeated lore for Eviledon, not as fully verified canon in the strict sense. Creator attribution is the messiest part of Eviledon's metadata.
The accessible web sources do not line up perfectly. Brainrot.jp credits the character to @sammy.
PlayBrainrot says Eviledon was made by Sammy, but that the video was made by @brainrotmaster900. The Italian Brain Rot Fandom page says the brainrot was made by SpyderSammy, while also listing a creator field as brainrotmaster9000 and repeating the note about a video by @brainrotmaster900.
The safest factual summary is that Eviledon is generally tied to Sammy or SpyderSammy as the originating Steal a Brainrot character, while @brainrotmaster900 is often credited by fan sites for the specific video or audio presentation. I did not find a directly archived primary post that cleanly resolves that split, so the attribution should be treated as partly uncertain.
Dates also require care. PlayBrainrot and the Italian Brain Rot Fandom both list October 10, 2025 as Eviledon's debut date.
Other Steal a Brainrot event coverage places the Witch Fuse Halloween event launch on October 11, 2025, and some guide articles about obtaining Eviledon were published on October 14, 2025, October 17, 2025, or October 19, 2025. That likely means the character entered community circulation around the event window in mid-October 2025, but the exact distinction between character debut, event start, and page publication is not perfectly documented in the sources that were available.
What can be said with confidence is that Eviledon occupies a recognizable niche in the Brainrot character web: it is a red demonic shark variant linked to Tralaledon, identified with Steal a Brainrot's Halloween and aquatic collections, and remembered for strong in-game value relative to many other Secret units. What cannot be said with equal confidence is which single creator account should receive sole credit, whether the tsunami brother-lore came from an official first upload or later fan documentation, and whether the correct first date is October 10 or October 11, 2025.
