Sonic (SSF2)

Sonic is a veteran starter character in Super Smash Flash 2. He was added to the game in Version 0.3. His sprites are custom-made and are based on his appearance in Super Smash Bros. for Nintendo 3DS and Wii U. His moveset is comprised primarily of attacks from Super Smash Bros. Brawl, 3DS/Wii U, Project M, and some original moves.

Sonic is currently ranked 20th on the tier list for Version 1.3.1.2 of the game. He has amazing mobility, with the fastest dash and ground to air speeds in the game, as well as a high air speed and falling speed. He has a great air game, as many of his aerials are strong combo or KO options with great frame data. His Spin Dash, Homing Attack, Spring Jump, and Light Dash give him even more quick burst options that can lead directly into more combos. These things give him a ridiculous rushdown game.

However, Sonic struggles with KOing somewhat, as his strongest tools have noticeable startup and require specific spacing to get successful hits, which often results in characters living to abnormally high percentages against him. Sonic lacks a proper projectile, giving him some difficulty dealing with campy characters. His recovery is very linear, as Sonic cannot use both Light Dash and Spring Jump in the same airtime, forcing him to choose between a fast horizontal option with a short travel distance and no vertical gain, or a long vertical option with slow movement and little horizontal gain.

Sonic's strengths outnumber his weaknesses, leaving him in high tier.

Attributes
Sonic is a very fast character -- the fastest in the game with a max run speed of 15.137 px/f. His attacks are also very quick, allowing for fast damage to opponents, but despite this, some of them lack range. They are also somewhat powerful, with forward air possessing a meteor smash when the sweetspot is contacted, back air being a potent kill move at just over 100% of damage (despite also being his slowest aerial), neutral air being an excellent combo tool, and up air is a very good kill move off the top. His Light Dash is also a good kill move when sweetspotted (because of this, it's slightly situational). His recovery is quite long (despite being linear) with Light Dash being able to sweetspot grab ledge, Homing Attack being able to extend it even further, and aerial Spin Dash also possessing the ability to extend it. He can also aerial out of up-b, normalizing drift speed by forcing Sonic into his regular falling animation.

However, Sonic has his weaknesses. As mentioned before, his recovery is somewhat linear. Homing Attack can only be used once in the air before he has to resort to using Spring Jump, so the way that his recovery can be beaten is by intentionally not hitting him back off the stage. He also lacks a useful projectile, so characters who possess a good projectile (ex. Falco) can easily shut Sonic down. (However, the Spring can be used for gimping.) Also mentioned earlier, many of Sonic's attacks lack range, so attacking the opponent requires Sonic to get in the opponent's comfort zone.

His strengths mostly outweigh his weaknesses, placing him in A tier.
