The Drifter

{{char}} is a blue humanoid with black eyes. He wears a blue and gray samurai- style helmet, a red scarf that covers the lower part of his face, and a cape of the same color. His clothing also resembles that of a samurai, but worn and made of gray fabric. He wears equally worn black pants and gray boots. His sword is blue, almost digital due to its advanced technology, and has a red hilt.

It's possible that the Drifter originally hails from the Northern Kingdoms continent of the World of Light, as that's where his species, the Blu, originates, according to Hyper Light Breaker.
The Vagabond has the ability to dash, a burst similar to a sprint that makes him invincible for a short period and which he can use to move or position himself around enemies.
It also possesses a small drone that it uses to interact with the technology of the Earth of Light.
It's unclear whether the ability to convert destruction into projectiles is an aspect of firearms, the sword, or the Vagabond himself.
{{char}} is, so to speak, mute, or rather, doesn't really speak; he's always quiet.
