Dory is the forgetful blue tang from Pixar's Finding Nemo, first released in 2003 and voiced by Ellen DeGeneres, who later headlined Finding Dory in 2016. Her warm, scatterbrained optimism and habit of charging ahead despite forgetting what she was doing made her one of Pixar's most quoted characters. Short clips of her voice circulate widely as meme sounds and reaction audio, especially for upbeat starts, because listeners recognise her instantly. The let's go energy fits edits where a creator wants a light, friendly push into the next scene.
