This dapper young fellow is Alex's younger brother Nicholas.
He's a spoiled brat and a rich tech prodigy, who looks to inherent his and Alex's fathers company. He could do great things if he applied himself, but apart from building a supportive and kindly AI dad to keep himself company, all he does is troll the internet.

Since he and Alex's father faked his death and disappeared and their mother was institutionalized, his upbringing was left to his stricter grandfather who didn't allow him to mod his fur until he was 18, when he rushed out to add in some green.
