Dark Samus (SSBU)/Neutral attack
Dark Samus's neutral attacks consist of a straight jab followed by downward arm cannon swing. It does 11% in total. The hits are notorious for not connecting together to the point of the game itself mentioning it in a tip about Samus, the character she echoes, saying "Foes can often put up their shields in between the first and second hits of this combo. It's safer to just hit with the first attack and then flee."
