- It is possible that the Renato brothers represent fans that despise the mainstream and popular fandoms. Where as just about every other character on their level uses a custom variant of a powerful Ace or at least Sub-Ace unit, they have been seen only using custom variants of weaker mass-produced units, like GMs. they also have expressed their dislike for the favorite fighters, such as being happy when the champion Carlos Kaiser was defeated by a newcomer, as well as their wanting to knock Tatsuya Yuki off his pedestal as the favorite to win the tournament.
