A

A travels together with Matthew, wielding a thin red sword. A is the type to make calm, calculated decisions, making for a good partner for Matthew, who tends not to think his actions through. A also tends to be logical to a detriment, often taking metaphors and phrases too literally, such as when A thought a rain of Brogs was going to happen when Matthew used it to poke fun at Glimmer warming up to him. A is in fact a fragment of Ontos, being born from his discarded "conscience" and retaining the memories of Ontos' time with Shulk as Alvis. Opposing Alpha's plans to create a new world at the expense of the people of Aionios, A seeks to stop A's other self.
