They are both Italian best friends who run the channel Lionfield. 

Emilanio is the one who has longer hair and Matteo has short hair. 

They like making shit posts of Italians, as they are Italians themselves. They also like reacting to pasta related videos and at the end of each video, they say either: Approved, or Not Approved.

They don't like it when people put pineapple on pizza, break spaghetti, or stuff like that.

They hold up a crucifix when people make a disgrace to the Italians.
