In a multiplayer game that features both Ness and Game & Watch, there is a glitch that turns Game & Watch into an unhittable projectile.

To begin, have Game & Watch use the Bucket to absorb three full-powered PK Flash attacks from Ness. After three attacks, the Bucket will be full. From there, have Game & Watch unload the Bucket onto a shielded Ness. Ness's shield will break, and Game & Watch will fly away from the impact at blinding speed.

Not only is it a glitch for Game & Watch to fly away from the impact in the first place, but he turns into a projectile that deals instant death to any other character he touches; furthermore, Game & Watch travels so fast that it's nearly impossible for an opponent to react to the glitch if they don't know that it's coming in advance.
