Bastion is a playable hero in Overwatch, Blizzard's team-based hero shooter first released in 2016. As an omnic robot, Bastion does not speak in normal sentences, instead communicating through electronic beeps, chirps and whirrs that players quickly learned to recognise. Those sounds became a core part of the character's identity and were widely shared as short clips on soundboards and in fan edits. They remain popular because they are instantly recognisable to Overwatch players, even without any dialogue, and they work as a quick, light-hearted signal in gaming content.
