Ross Roosevelt

Ross Roosevelt is the deuteragonist of A Golden Drive Through Equestria. He's a veteran Displaced who acts as the Roidmudes' Grim Reaper, wearing the costume of Ruby Rose.

Past
Prior to the story, Ross was Displaced into the Equestria Girls universe where he left his Token in the care of the Roidmudes. Not much is known of his escapades though.

Ross bumped into Kelly and their conversation led to Kelly meeting with Zoloto and resulting in her getting the Banno Driver.

Golden Drive Arc
He briefly appears at the end of the second chapter, being summoned by the Roidmudes and asking who his next target is.

Personality
Not much is known of him so far outside of a double life he has and that he's into RWBY.

Niko Zoloto
Ross obtained both a replica Crescent Rose and his Token from Zoloto. He speaks pretty highly of him, as he recommends to Kelly that she buys something off of him. It's implied that Ross knows he's a Displacer, as he backs away when Kelly took the Banno Driver.

The Roidmudes
While not much is seen with him, his appearance is met with fear from the Roidmudes, earning him the nickname of Grim Reaper, though from his words to their leader, it appears that he's sort of their hitman. His words about them are that they're "capable".

Powers
While it's not seen, it's implied that Ross has Ruby's Semblance, allowing him to have super speed to the point where it seems like he's teleporting.

Along with this, he possesses the Crescent Rose, or rather a replica of the sniper-rifle/scythe hybrid.

He has his own Token, which is designed to be a necklace featuring a metallic version of Ruby's symbol.

Trivia

 * Keeping with the Color Naming Rule in RWBY, Ross Roosevelt's name relates to a color. In his case, his last name, Roosevelt, means "from rose field", and his first name is close to the word rose as well, tying to his costume of choice, Ruby Rose.
