The clip is tagged for Broly, the Legendary Super Saiyan villain from the Dragon Ball series, and uses his arrogant battle line about never being surpassed. Short Japanese anime shouts like this spread widely on soundboards and in fan edits because a single word carries the whole character's threat. The drawn out dekinuu delivery became a reusable meme sound for power scaling jokes, mock battles and overconfident villains, and it remains popular with editors who need an instant anime boss moment without using a longer dialogue scene.
