Bucky appeared on 4chan and was briefly popularized in 2019 (see: knowyourmeme). His origins are somewhat uncertain, with some 4chan contributors speculating that he may have been created by Discord users before making his way to the boards. Bucky is depicted as a bright green-skinned character, exuding an unmistakable "don't care" energy – his flat expression and minimalistic design lending themselves perfectly to deadpan humor, absurdist edits, and surreal memes.

Bucky was tokenized and deployed onto Ethereum through Bonk.Fun, with the community leading new memes and carrying his legacy forward with relentless brainrot, cursed art, and chaos on-chain.
