Relationship With Smosh
Due to Ryan and the Smosh duo both being original "famous" YouTubers and YouTube sketch comedians around the same age, having even lived close to each other before, they are good friends who meet up with each other every once in a while.
Smosh and Ryan Higa Collaborations
He appeared twice on the main Smosh channel in 2010, in the episodes "If Cartoons Were Real" as a confused school student and "Pokemon Theme Song REVENGE" as the boss of a group of ninjas sent by The Pokémon Company to kill Anthony and Ian for making another Pokémon-related video. He has also appeared in an episode of Ian is Bored. In the episode, "Kicking NigaHiga's Butt!" Ian and Higa face off in a wrestling match with Ryan winning due to him being a trained High School professional wrestler compared to Hecox who had no prior training.
Ryan has also created a 35-minute movie on YouTube called "Agents of Secret Stuff," featuring Anthony and Ian. He as well was drawn in an episode of Ian is Bored, "EXTREME YOUTUBER DRAWINGS! " as he was one of the YouTubers drawn by Anthony and Ian. He then appeared in The End of Christmas (Part 1) and The End of Christmas (Part 2) as a puppet.
Ryan Higa is then played by Anthony Padilla in HOW TO BE A YOUTUBE COMMENTER where he is annoyed by Old Man Grandpa due to him being in his room. Shortly after being disturbed, Old Man Grandpa accuses him of being in the Illuminati.
In 2015, a year later, Ian and Anthony is featured in one of Ryan Higa's "I Dare You" videos, the same month in May, taking part in his "Thank You Mom" video featuring Ryan, hd fans, and other YouTubers thanking their mother's presence. Later that year, he would appear in EVERY SMOSH VIDEO EVER along with his childhood friend and half of the former "nigahiga duo", Sean Fujiyoshi humorously imitating Smosh's Food Battle Series.
In 2016, Ian and Anthony appeared in his ten year anniversary video on his second channel, HigaTV, which consisted of YouTubers and fans of Ryan reacting to his ten year anniversary on YouTube and Ryan reacting to both them and the occasion.
In March 2017, Ryan's Higa's likeness is featured in the form of a cardboard cutout in WE'RE STUCK IN FAN FICTION!
