Thought I'd share my Smash Ultimate DLC set that I made with that template making its way around the Internet:
It's one for my most character for Smash, who is also my favorite fictional character around: Professor Layton!
He'd fit perfectly as the puzzle game rep on the roster. I imagine his moveset would contain elements from many of the puzzles he solved in the series: the moving block puzzles, the milk transfer puzzles, the magnifying glass, and a lot more. He could also use various archaeological tools and artifacts to reference the fact he's an archaeology professor. His special moveset would probably involve the inventions he made using his powerful intellect, and his Final Smash would be a cinematic clip of the "Deduction" cutscene where he figures out who the real culprit behind the crime is, delivering some major damage to the foe that is targeted.
I chose London to be the stage since it's a reoccurring place in the series. The place where Layton works, Gressenheller University, is stationed here, and so are other major landmarks like Scotland Yard headquarters and Kensington Street. The city was also the main setting in Unwound Future and Layton's Mystery Journey, was the location of Azran Legacy Chapter 3 took place, and was the place our characters were at some point in each Layton game. I imagine this would be a traveling stage, where the battlefield visits London's most iconic and the characters fight there. The way this stage would transition between the various landmarks would probably be like what Castle Siege does with its locations, seeing how huge London is.
As for the music tracks I chose:
Professor Layton's theme
London 3
Puzzle Battle
Descole's Theme (Live Version)
Targent's Theme
Airship Chase
Theme of the Last Battle (Live Version)
Theme of Unwound Future
Theme of Miracle Mask
Theme of Azran Legacy
I can list several more tracks, but those ten take the cake for the tracks I want to see the most. The Professor Layton series has such an amazing soundtrack that practically every track that was in those games are deserving to be in Smash!
For the remixes, Yoko Shimomura needs to compose one of them. Her music closely resembles tracks from the Layton series (just listen to Route 10's theme from Smash 4 to get an idea), so she needs to compose a Layton track or two if Layton makes it into the game.
Whoever composed the Melee Battlefield remix in Smash 4 should also remix a Layton track too. The epic opera heard in that track sounds really fitting for a remix of either Descole or Targent's themes!
