Of all the main characters I feel like Roman changed the most as the movies went on.

He was still full of personality in 2f2f but I feel like he was definitely more grounded of a character in that film. I’d say somewhere along 7 or 8 was when he became a caricature of himself. Don’t get me wrong I still find him hilarious and enjoyable but I just found it funny that whatever character development he started with just evaporated as the franchise went on.
