I just found out about this Karl Rock https://en.wikipedia.org/wiki/Karl_Rock, who is a youtuber and I couldn't even check his age in any source. On the other side is Pewdiepie - another youtuber, if you've heard of him. Strangest thing, Pewdiepie had a beef with India's channel Tseries for most views. And Karl Rock is mostly vlogging from India and has perfect Hindu. You also can't find anything about this guy. Still, his nose lines, ears, eyebrows, beard and hair line all seem to be similar to Felix's. Either a twin, a brother, or a cousin. Just hear them both talk, there are even similarities in the voices.

Here Karl is trying to give a cake of Pewdiepie to Tseries: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse2.mm.bing.net%2Fth%3Fid%3DOIP.PyD5MY-0HKTcE-saBLZB6QHaFj%26pid%3DApi&f=1
