Pikachu is the mascot of Pokemon, and this short cry comes from Super Smash Bros. Ultimate, the Nintendo fighting game where Pikachu appears as a playable fighter. Short character cries from Smash Bros. are widely clipped for edits because they are instantly recognisable and carry clear emotion in under a second. This angry version is used online in reaction videos, gaming montages and memes to signal frustration, usually without needing any explanation, which keeps it popular with Pokemon and Smash Bros. fans.
