The journey began in July 2025, when Ethereum Core Developer Nixo shared an updated blog post outlining the various upgrades and their corresponding mascots. While most were decided, the space for the Fusaka upgrade remained conspicuously empty. The community waited in anticipation for the chosen symbol of this pivotal moment in Ethereum's evolution.

Then, in September 2025, Nixo confirmed it. The Fusaka Upgrade officially has a mascot: a zebra. This confirmation, shared on X, solidified the zebra's place in Ethereum history.
