in Project M
|Universe||Sonic the Hedgehog|
|Base game appearance||Brawl|
|Moveset inspiration||Sonic (SSBB)|
|Alternate costume||Jet Set Radio, Racing Suit Sonic (Project+)|
Sonic is a playable character in the Brawl mod Project M. He has been buffed for his Project M showing. Sonic is currently ranked 10th out of 41 characters on the official tier list, near the top of A tier, and a considerable improvement over his placement in Brawl, where he was 22nd out of 38. In the official Project+ tier list, he is ranked 4th at the top of the A+ tier, another considerable improvement over his placement in Project M.
True to his series, Sonic is the fastest character in the game, having the fastest dash speed and a fast air speed. These traits make him able to rack up damage very easily and execute combos across the stage. His strengths include extremely fast and tricky movement, a great combo game, good edgeguards, and one of the best recoveries in the game. He has been given the option to moonwalk as a result of the game's return to Melee physics, which can help mix up his approach. He also now has the ability to dash jump, which almost doubles his already fast air speed. Sonic also sports a plethora of recovery options, as all four of his special moves can help him recover in some capacity.
While Sonic was known in Brawl for his high speed and movement, he was held back by his poor KO potential due to his extremely weak attacks and few finishers, all of which were unreliable and ineffective. This has been addressed in Project M, as he has been given more KO power in his moveset, making him stronger than before.
Sonic's flaws include having poor range on most of his moves (in addition to a lack of projectiles), poor hitbox placements, and weak horizontal and vertical endurance due to being light with only an average falling speed (even floatier characters like Samus take less vertical knockback due to her extra weight), while also being very susceptible to juggles despite generally not being easy to combo. As such, while Sonic can combo easily due to his maneuverability, he himself is very easy to K.O. at lower percents, as attacks with high power can send him flying off the stage for good despite his multitude of recovery options, and his low range and lack of projectiles compel him to come close to his opponents rather than harass them from afar. As such, Sonic must make use of his speed and movement options in order to open up opponents and compensate for his weaknesses.
Changes from Brawl to PM
Sonic was buffed in transition to PM. His already impressive mobilty has been improved, he has more KO power and many of his moves have been altered to be more reliable and have more utility. While he has seen some nerfs mainly to his endurance and recovery, he overall has much better tools and the new mechanics of Project M benefit him more than they hinder him.
- Up taunt now features a horizontal spin and finger wag. Additionally, all of Sonic's taunts can be held indefinitely by holding down the taunt button.
- Sonic can now taunt cancel all three of his taunts.
- Sonic has all new alternate costumes with one of his costumes being based on "Jet Set Radio".
- Sonic's already impressive Dashing speed was further increased (3.5 → 4).
- Sonic's air speed was negligibly increased (1.1092 → 1.11).
- Sonic's jumpsquat is faster (5 frames → 3).
- Sonic's falling speed was increased (1.45 → 1.9) although it is lower relative to the cast.
- Sonic's gravity was increased (0.085 → 0.111).
- Sonic's traction is higher (0.07 → 0.085) although it is lower relative to the cast. While this makes it easier for him to punish out of shield, it also means that his new wavedash covers below average distance.
- Sonic's already low air acceleration was decreased (0.05 → 0.045).
- Sonic is significantly lighter (95 → 82). When combined with the removal of momentum canceling, this drastically worsens his horizontal endurance although his vertical endurance is similar due to his higher fall speed.
- This weight change however allows him to be knocked down by Fox's shine.
- Grab release glitch from Brawl has not been removed.
- Sonic's glide toss covers less distance.
- Jab combo does more damage (7% → 10%) and the second and third hits have longer durations (frame 2 → 2-3 (hit 2), frame 3 → 4-6 (hit 3)).
- The third hit of jab has more startup lag (frame 3 → 4) and the removal of jab locking hinders jab's damage racking potential if the opponent misses a tech.
- Forward tilt is now a single hit, while still dealing 11% if the sweetspot connects, and it has slightly more KO potential despite its decreased knockback scaling (115 → 90). It also has less ending lag (frame 35 → 32).
- Forward tilt has more startup lag (frame 6 → 7).
- Up tilt is now a flash kick with a single hitbox instead of a double high kick based off of Sonic Up Draft from Sonic Battle. It acts better as a launcher, with less startup (frame 7 → 6) and ending lag (frame 50 → 30) and it has a lot more utility than the old up tilt.
- New up tilt deals less damage (14% → 11%).
- Down tilt has a longer duration (frames 6-9 → 6-10) and has more combo potential due to the removal of hitstun canceling.
- Down tilt's IASA frames are later (frame 28 → 29). It can also no longer be used as a pseudo crawl.
- Dash attack has less startup lag with a longer duration (frames 5-23 → 2-22), has less ending lag (frame 43 → 40), the clean hit deals more damage (6% → 8%) and deals higher knockback.
- Forward smash has less startup lag with a longer duration (frames 18-22 → 16-22), has less ending lag (frame 45 → 42), deals more damage (14% → 16%) and has increased knockback scaling (98 → 100) improving its KO potential.
- Forward smash now has a late hit which deals less damage (14% → 12%) and knockback (30 (base), 98 (scaling) → 10/85).
- Up smash has less startup (frame 19 → 18) and much less ending lag (frame 66 → 50) and it is no longer a multi hit only having two hitboxes. The first is weak, while the second is much stronger and deals more damage (5% (hit 1), 1% (hits 2-7), 3% (hit 8), 14% (total) → 2% (early), 16% (clean)) and produces more knockback (70 (base), 153 (scaling) → 37/102) making the move much more reliable and improving its KO potential dramatically.
- Sweetspots of neutral aerial and up smash now have a slash effect, and the former has a new look inspired by Sonic 3.
- Sonic's DACUS covers less distance and he gains less distance when performing up smash out of a dash greatly hindering up smash's approach potential. It also has a shorter overall duration (frames 19-32 → 18/20-24).
- Down smash changed to a multi-hitting "break-dance" move reminiscent of his Heavy Attack, the Sonic Flare, from Sonic Battle. It acts similar to the original, but has less startup (frame 17 → 10) and ending lag (frame 58 → 51) and and deals higher damage (12% (early), 9% (clean), 7% (mid), 5% (late) → 15% (front), 12% (back)) improving its KO potential despite its decreased knockback (40 (base), 100 (scaling) → 25 (front), 20 (back)/91) and can punish shielding or crouch canceling foes more effectively.
- New down smash has less range and a shorter duration (frames 17-37 → 10-19 (front), 24-30 (back)).
- Neutral aerial has a new initial hit which deals more damage (11% → 15%) and has stronger knockback and has a larger hitbox. It also has less startup (frame 6 → 4) and ending lag (frame 47 → 31) and auto-cancels earlier now doing so in a short hop.
- Neutral aerial has more landing lag (12 frames → 15).
- Forward aerial is now a front-flip kick, based on the Sonic Eagle from Sonic Battle. It has much more utility, covering a wider area in front of Sonic and meteor smashing at the heel of his foot, which when combined with his enhanced air speed gives Sonic a deadly Ken Combo. It also has less landing lag (30 frames → 22), and is much more reliable due to no longer being a multihit.
- New forward air deals less damage (14% → 11%). It also has more startup (frame 5 → 8) and ending lag (frame 36 → 38).
- Back aerial now has a sweetspot on Sonic's foot which deals more damage (13% → 16%) improving its KO potential. It also has a longer duration (frames 13-16 → 13-21) and less ending lag (frame 37 → 34).
- Both the early and late hits of back aerial now have a sourspot which deals less damage (13% (clean), 9% (late) → 12%/6%) and the sweetspot has reduced knockback scaling (94 → 90). Back aerial also has more landing lag (9 frames → 18 (although it's landing lag is identical when L-canceled)) and it auto-cancels later (frame 29 → 33).
- Up aerial's second hit has less startup lag (frame 14 → 10), both hits link better as the first hit has reduced set knockback (90 → 30) and hitlag and the second hit comes out faster, deals much more damage (3% (hit 1), 6% (hit 2) → 4%/13%), the hitbox at the tips of his shoes has stronger knockback (63 (base), 90 (scaling) → 25/100), and the initial hitbox is a spike.
- Up aerial no longer auto-cancels as soon as the hitbox ends (frame 19 → 32) greatly hindering its use as a landing option.
- Down aerial deals more damage (8% (clean), 7% (late) → 10%/9%) and has more knockback on its sweetspot, has significantly faster startup (frame 16 → 9), and is now better at starting aerial combos due to the removal of hitstun canceling and its lower landing lag (30 frames → 28) which can be further reduced with L-canceling. It also now has a meteor smash hitbox and it auto-cancels earlier (frame 39 → 36).
- Down aerial has a much shorter duration (frames 16-37 → 9-24) now giving it a fair amount of ending lag after the hitbox has deceased.
Grabs and Throws
- Standing grab has more startup lag (frame 6 → 7) and standing and pivot grabs have more ending lag (frame 29 → 31 (standing), frame 35 → 36 (pivot)).
- Forward throw sends opponents at a more horizontal angle. This hinders its follow up potential but gives it tech chasing potential.
- Up throw sends opponents at a slightly different angle (100° → 95°) and the removal of hitstun canceling and the increased falling speeds improve its follow-up potential.
- Up throw deals less damage (12% → 8%) with altered knockback (65 (base), 70 (scaling) → 95/60) hindering its combo potential.
- Down throw is faster, giving the opponent less time to DI.
- Homing Attack can hit even when facing the other way and has much faster startup and fires straight at the opponent, now homing on them much more consistently in addition to juggling them at medium percentages.
- Homing Attack has a slightly decreased detection radius, and gives less distance when there is no opponent in range, and has less KO potential. Additionally, if Sonic does not hit a wall or at least target anybody, he will go into helpless state and if he does hit a wall with it, it has a lot more ending lag no longer giving him an infinite stalling option.
- Pressing the attack button during the startup of Homing Attack lets Sonic use the Blast Attack, which is a faster Homing Attack with less ending lag, though it has less range and doesn't track the opponent. Sonic now strikes a pose after successfully hitting with a Homing Attack.
- Side special is now Somersault: a fast-starting spin attack with a variable height jump depending on how long is the special button held. Pressing the attack button turns the attack into a sliding kick similar to that of the Sonic Advance games. Both attacks cancel upon falling off a ledge. This gives Sonic a new multi-hitting quick attack to efficiently rack up damage and then launch foes, rather than a move almost identical to his down special. It also sweetspots ledges when used in midair, improving Sonic's horizontal recovery.
- Spring Jump gives slightly less vertical distance, and Sonic can no longer air dodge after performing the move; also, using it causes Sonic to lose all of his momentum as a result of the move resetting. He can also no longer re-use it if he is hit out of it with Mario's Cape.
- Falling animation after using Spring Jump is now identical to his helpless animation, though without the black overlay. Sonic now additionally spins horizontally during the rising portion of the move in a manner similar to Sonic CD.
- Down special is still his Spin Charge, but has gained most of the nuances the original Spin Dash had while retaining all of its own properties. It can additionally damage opponents when being charged.
- Spin Charge can no longer be held indefinitely.
- Super Sonic is considerably weaker as he can no longer deal damage when idling and his ram deals less damage (18% → 16%). The increased falling speeds also further hinder his KO ability.
