Among the Brawl community, it is common for distinguished groups (such as the Smashboards Back Room) to create Tier lists, rankings of a character's potential in tournaments. The Smashboards tier list is generally seen at the "official" tier list, though many other groups have created their own.

Criticism of tier lists
There are many people in the Smash Bros. community who disagree with the idea of tier lists. They believe that all characters in the series are relatively balanced in ability. Such people are known as "Anti-tierists". A common argument against anti-tierism is that it is extremely difficult to perfectly balance a cast as diverse as that in Super Smash Bros.
