LuigiFan00001 (AKA: Matt) is a Youtube creator specialising in puppet work from various popular franchises ranging from Mario to Plants vs. Zombies. He is able to generate various different voices, in some surprisingly odd pitches and tones. Despite his young age, he has been making puppet videos on multiple different channels for over 5 years. He is a good friend of Strider and gives him the voice role of "King Boo" on occasion ( https://www.youtube.com/watch?v=wrk54G2mveE ). Luigi seems to have a gnack for making viral videos, inspiring Strider with his steadfast dedication to his channel over the years.
Luigifan00001 has had over 3 successful channels over the last 7 years, starting Youtube at a very young age.
