Basic Animations:
Walk: Layton would walk normally like he does in the games.
Run: A basic running animation. Visually, it resembles the scenes when he chased the Black Raven in Last Specter and the moment the Giant Float is about to collapse on him in Miracle Mask. He has the same running speed as Snake.
Jump: He lunges upward in the first jump. With his second jump, he curls his body, but it doesn't give him too much vertical distance. It is very similar to Snake's jumps, but Layton's up special makes up for it.
Fall: Layton holds onto his hat with one hand while his other arm is held out, slightly bent. He has relatively fast falling speed as he is a bit of a heavy weight.
Crouch: Layton bends with one knee while one arm rests on it.
Crawl: A basic crawling animation where Layton crawls with his knees and hands.
Shield: Layton grabs his hat with one hand, while his other arm is bent and hovers over his chest.
Roll: Instead of rolling, Layton slides to the outside of the stage. When returning back, he has one hand on the ground as he bends his body forward.
Side-step: Layton grabs his hat with one hand and moves toward the back of the stage with a surprised expression while his other arm extends far to the side.
Dizzy: Layton grabs his hat with one hand and stumbles from left to right.
Sleep: Layton sits down with his legs crossed while resting his head on one of his arms.
Swimming: Layton moves his arms similar to a breast-stroke pull.
Drowning: He lowers his hat over his eyes with one of his hands, while the other arm and his legs float helplessly in the water.
Idle Animations:
-Animation 1: Layton adjusts his hat.
-Animation 2: Layton holds his hand to his chin, taking a thinking position.
-Animation 3: Layton pouts his arms and slightly nods his head.
Launching scream: Layton screams, "Uuwaaahhh." It sounds similar to the scene when he tumbles with Luke through the forest in Azran Legacy.
KO scream: Layton screams, "Huaghh." It sounds exactly like his scream when Emmy crossed his path at the beginning of Last Specter.
Star KO scream: Sounds exactly like his scream from Azran Legacy when the beam of light was killing him.
Basic attacks:
Jab: Layton delivers a small slap with his right hand while raising his pinky (supposed to be a gentleman's slap).
Double Jab: The second jab is another gentleman's slap, but he uses his left hand instead.
Triple Jab: Layton pulls out a fencing sword and uses it like he's in a fencing match. It can lead into a repetitive jab, and the final blow is the finishing fencing move that touches the opponent.
Dash Attack: Layton pulls out a metallic pipe and slashes from left tor right. The attack manner is similar to Marth's dash attack.
Tilt Attacks:
Forward Tilt: Layton holds out his magnifying glass, and the tool gives the same orange tint just like it does in the games when you find something of interest (even producing the same sound effect). The moment when the magnifying glass turns orange is when damage is delivered.
Up Tilt: Layton takes an "a-ha" stance as the iconic red exclamation mark from the games appears above his head. This exclamation mark is what deals the damage, and it is his strongest tilt attack.
Down Tilt: Layton uses an archaeological hand pick and does a hammering animation using it.
Aerial Attacks:
Neutral Aerial: Layton grabs a camera by its strap and swings it around himself.
Forward Aerial: Layton uses the same metallic pipe and moves the pipe downward. Visually, the attack resembles Layton's first strike on Descole when Layton released himself from the Fossil Glider in Azran Legacy.
Back Aerial: Keats the Puzzle Cat emerges from Layton's coat, and the cat slashes foes from behind Layton's back before returning to his coat. During this animation, Layton watches Keats with a surprised expression and quickly helps Keats return back into his coat.
Up Aerial: Layton pulls out the toy robot from Miracle Mask and holds it above his head. The toy robot then does a small, upward jump from Layton's hand while moving its arms up. This attack has a dual-damaging effect where it can potentially deal two blows to the opponent. There is a sweet-spot at the robot's arms.
Down Aerial: Layton takes a shovel and stabs it toward the ground. The attack heavily resembles Link's down aerial, even having the same meteor spike if the opponent is hit by the sweet-spot.
Grabs:
Pummel: Layton knees his opponent.
Each of Layton's throws reference various puzzles throughout the series. In each throw, he releases his opponent and changes into a thinking position. Upon releasing his opponent, the throw takes place. After the throw finishes, he looks up with a grin on his face, just like when a puzzle is correctly solved. Think of it as if Layton uses his intellectual thoughts to attack the foe. It's like Layton is playing "mind-games" with his opponents!
Forward Throw: A small toy train (as seen from a bird's eye view) appears above Layton, moves toward the opponent, and latches onto him/her. The train quickly moves slightly forward then diagonally upward before disappearing and releasing the opponent. It mimics those "drag the line" puzzles where you need to get a chain to another side, usually involving trains of some sort.
Back Throw: Three pitchers appear in front of Layton. The opponent is then thrown between the pitchers as if he/she is being poured like milk. It mimics the milk puzzle from Curious Village.
Up Throw: Three rectangular blocks push the opponent upwards, with the final block releasing the opponent high. It's a weak attack with high knockback, mimicking those "drag the blocks to get a certain piece to the other side" puzzles that are very common throughout the series.
Down Throw: A tetris-shaped block pushes the opponent downward. A second one pushes the opponent in a direction behind Layton. The last piece pushes the opponent upward. This ultimately creates a rigid U-shaped throw. It mimics those "fix the pictures" puzzles that is akin to assembling a jigsaw puzzle, but the pieces are more tetris-shaped.
Smash Attacks:
Each of these attacks involve the Azran Keystone from Azran Legacy.
Forward Smash: Layton pulls out the Azran Keystone casually holding it to the side for the charging animation. Once he finishes charging, he extends his arm holding the Keystone in front of himself. The Keystone then delivers a shockwave-like blast that deals tremendous damage to foes. The blast looks exactly the same as the one that was produced from the device in the games.
Up Smash: It plays out almost identically to the forward smash. The only difference is that Layton holds the Keystone above his head for the finishing blow, and the blast deals vertical knockback.
Down Smash: Unlike the forward and up smashes, Layton puts the Azran Keystone on the ground and holds it there for the charging animation. Once fully charged, the Keystone emits the the same blast, only this time, it covers a 360 degree radius surrounding Layton.
Specials:
Standard Special - Coin-Slot Machine Gun: Layton pulls out the same gun of the same name he created in Unwound Future. He charges it then and fires a barrage of coins. The length of time it takes to fire the coins depends on your charge time. Layton can move left and right while firing his gun, but he cannot turn around while doing so. The barrage of coins has the same effect as firing multiple, small shots from the Super Scope, but unlike the Super Scope, you can combo into a grab by moving toward the foe as you fire coins to keep him/her stunned. The gun can fire for up to five seconds at most. You can't use it right away after the gun finishes firing because the next Layton uses the attack, he will dump a bag of coins to prepare for the next attack. It takes about one second for Layton to dump coins. Once he finishes doing so, you can charge and fire again.
Side Special - Hamster Attack: Layton throws an apple, and if it hits someone, it does a small amount of damage. If he uses the side special again, he will throw the hamster this time, and it will quickly run towards the apple. As the hamster runs, it can climb up walls similar to the Bombchu, and it can anyone in its path with small damage. Once it reaches the apple, the hamster eats it. If an opponent is right next to an apple, he/she will be trapped by the hamster as it eats the apple and wrack up damage with each bite. Basically, the hamster is biting the opponent's feet in the process. With the final bite, the opponent is launched with decent knock back.
Up Special - Globe Glider: Layton uses the Globe Glider he built from Curious Village. When utilizing it, he faces towards his front. The glider can travel very high and is easy to maneuver, similar to Snake and ROB's up specials. This attack makes up for Layton's low second jump, repeating a similar deal to Snake's recovery. The glider can also disrupt an opponent's up-special when it makes contact, but in doing so, the glider will lose control for a few seconds before Layton is forced to dislodge himself. This references the scene when the glider slightly touches Don Paolo's helicopter in Curious Village, disrupting it to the point Don Paolo is forced to flee. When his up special finishes, Layton is not rendered helpless.
Down Special - Stone Catapult: Layton pulls out the catapult he uses to take down Descole in Last Specter, but it has been scaled down to closely match his size. He charges the catapult toYou can charge the catapult so that two stones can be launched farther. The farther the stones are launched, the more knock back and damage they deal. The stones deal more damage if they hit a foe that is in the air.
Final Smash:
Deduction: A cinematic Final Smash that references the most iconic cutscene in every Layton game where the Professor identifies who the real culprit behind the crime was.
The Final Smash begins with Layton taking a thinking stance and saying, "Hmmm." A glint appears in front of Layton and covers a small yet decent range in front of him. If anyone is caught within the glint's range, the screen turns white.
The scene then changes to show several people, including the culprit, sitting around a table in an old-fashioned living room, with Layton standing behind them. The people are all shadowed save for the the opponent that was caught by the glint. While taking his classic thinking stance, Layton walks around the room and says, "Someone here was the mastermind behind this awful scheme." He then looks forward the opponent and does his signature point at him/her, telling the foe, "And that person was you!" At that moment, the opponent takes on a funny stunned animation, indicating their shock at being caught. The scene then returns to the battle, only this time, the caught foe is delivered a large amount of damage and knockback. That attack can KO as early as 50%.
If Layton caught two or more foes, the scene plays out like it normally does. The only difference is that Layton uses plural nouns at the respective moments. While walking around and thinking, he says "some people" instead of "someone," and when deducing the culprit, he says "those people" instead of "that person."
I can also imagine a nice Easter Egg where all the shadowed people are individuals that appeared in past Layton games.
Taunts:
Up Taunt: Layton adjusts his hat, then pouts his arms. As he pouts his arms, he says, "Every puzzle has an answer."
Side Taunt: Layton tips his hat forward and says, "A remarkable move!"
Down Taunt: Layton pulls out a cup of tea and drinks it.
Victory Animations:
The victory melody would be a more melodic version of the "Puzzle Solved" soundbite, heard in the video brought up with the first animation.
Animation 1: Layton puts his hand on his chin, closes his eyes and looks down, then looks back up at the camera. He follows with his signature point and says, "I've found the solution!" This entire animation plays out exactly like the "Puzzle Solved "bit after solving a puzzle. Here's a video for reference:
Remove the black stills that interrupt at the different intervals to make the whole animation more fluid, and that's how it would likely play out in Smash.
Animation 2: Layton adjusts his hat and says "A true gentleman leaves no puzzle unsolved." He finishes with a pout while smiling at the camera.
Animation 3: Layton brushes both arms of his coat as if he is removing dust. As he does so, he states, "That was quite the riveting match!" He then adjusts his coat by putting both hands on the zipper sides to tuck his coat up.
Losing Animation: A basic losing animation that involves Layton clapping towards his left side while holding a smile on his face.
. If there were complaints I’d sit and watch the chaos ensue though
