List of tier lists for Super Smash Flash 2

Super Smash Flash 2 ' s tier lists have been elaborated by the Smash Flash Back Room since demo v0.6 and has undergone multiple changes to appeal the new demo updates or changes of the metagame. This is a list that keeps track of old tier list revision, including the current revision released.

v0.6 tier list 1
The first official tier list was released on October 3, 2010. The method to obtaining the lists was that each member had a chance to submit a rankings list, with the characters ranked from best to worst. In the calculation process, characters were awarded 9 points for a first place, 8 for a second, etc. all the way down to 1 for a last place on a list. Each character's point totals were then averaged, with the top and bottom rankings for each character excluded to control for outliers. The characters were then organized into tiers based upon significant gaps in point averages. would take the top place in this iteration while would be "anchored" to the lowest tier by many years.

v0.6 tier list 2
Prior v0.7 release, as new tier list was released on January 1, 2011. The second list was conceived in the same manner as the first and appeared to be more accurate with the rise of to the top spot, who many members noted to be superior than.

v0.7 tier list 1
The first v0.7 tier list was released on March 19, 2011. Because of the new character additions and balancing changes, several characters' positions changed, some drastically. ascended to the top of the list, while the previous top tiers, Sonic and Link, fell to B tier. The method for determining this list remained unchanged from the previous lists.

v0.7 tier list 2
Conceived on May 11, 2011, this tier list was the first to assign rankings for characters based on simulated tournaments rather than through the backroom voting system. Tournaments involved 128 random entrants in a single-elimination bracket where the outcome of each set was determined based on the matchup data generated for each character. The total number of 1st-place finishes for each character over approximately one million tournaments served as an unbiased and accurate way to formulate a tier list. As Kirby's fourth consecutive time placing in the bottom-most tier, said tier would be jokingly called the "Kirby n' Friends Tier", whom Kirby shared alongside.

v0.8b tier list
Because of technical issues, v0.8 was split into two versions, the former of which never saw a tier list. Eventually, v0.8b had its tier list released on July 12, 2012. As with the previous demo change, the characters' positions were once again shuffled. Kirby, for the first time ever, was not placed in his own tier, and Wario shot up to the number one spot. Conversely, Sonic would have his worst positioning yet, falling into Kirby Tier. This is the first time that a demo did not have a second tier list.

v0.9a tier list
This is the first tier list released following the merge of the Back Room into the McLeodGaming Forums. This list saw the return of Sonic to the first position, which had not occurred since v0.6. Wario dropped to the 12th position while Ness fell drastically to 22nd. Ichigo dropped to C tier for the first time after having placed consistently within the A-B tiers since the first list. As with tradition, the bottom tier is referred to as "K". Peach occupied the last position for the first time.

v0.9b tier list 1
This list shows Meta Knight jumping up to first place and replacing Sonic. Sonic drops down to B tier. Peach and Link rise out of K tier, which is no longer going to be a tier in future lists. Peach rises to B tier, while Link rises to A tier. Sora drops to C tier, a place he has not been since the demo v0.8b list. Mega Man also drops to C tier. Lloyd finally rises to S tier and becomes a top tier character instead of his usual spot of being in the middle or close to the bottom. Black Mage rises to A tier and is no longer a mid or low tier for the first time. Goku remains in A tier, but drops to the bottom of it.

v0.9b tier list 2
This tier list reflects the change in the meta over the course of seven months, from mid-April to mid-November 2015. During this period, it became quickly apparent that the top four characters were notably better than the bottom two, which caused the latter two to fall out of S Tier. Zelda, Sheik, Goku, and DK jumped up quite a few places due to players discovering how to exploit their strongest, fastest, and most disjointed moves to their full potential. Bomberman made a significant jump mostly due to the antics of WRXJoey, returning to A Tier. Meanwhile, Black Mage, Yoshi, Captain Falcon, and Link were found to be unable to live up to their original expectations, and have thus fallen drastically, with all but Black Mage falling out of A Tier entirely. By far, the most significant rise was Mega Man, who rose nine places to enter into B Tier as a result of significant discoveries in his zoning/spacing game. Since April, Mario, Peach, Ness, Jigglypuff, and Sonic have all but stagnated in terms of character development, causing them to fall into C Tier. Sonic in particular has fallen seven places, giving him the worst drop of this tier list. With new innovations appearing in Chibi-Robo's game, Sora has taken his place as the worst character in the game.

Due to the large size of both A Tier and C Tier in relation to S Tier and B Tier, they have been split into A+/A Tier and C+/C Tier. As such, the gaps between A+/A Tier and C+/C Tier are considered to be notably smaller than the standard tier gaps.
