Weed Yosuke

Weed Yosuke (also sometimes called Stoner Yosuke) is a recurring character in the Unmodified Gameplay series of videos. He first appeared in a Persona 4 mod where Yosuke's in-battle voice clips were replaced with an assortment of NPC voice samples ripped from Grand Theft Auto V. These voice samples were recorded by Yosuke's English voice actor, Yuri Lowenthal, and sound almost identical to his delivery in Persona 4. However, the NPC was written as a stereotypical stoner caricature, a stark contrast to Yosuke's characterization.

Persona 420
The first video, Persona 420 (posted on April 20, 2016) was created over the course of one day and released as a mod for Persona 4. In it, Yosuke wears a Bob Marley shirt and has brand new voice lines derived from the GTAV rip. Originally intended to be a one-off joke video, the trend of posting a gag on 4/20 instead of 4/1 (April Fools) eventually became an annual tradition for the ShrineFox channel.
