Ace Attorney Stage
Courtroom
Yeah, well, someone was going to submit it. So here we go.
The courtroom is the main place of gameplay in all Ace Attorney games, so it only makes sense that it would be the location chosen for Smash. This is roughly what the scene would look like, with the area in front of the stand and benches being playable. The 2 walls of the trial grounds floor will remain there, with both of those being breakable walls making walkoffs possible. It will be possible to go on top of those walls as well as on parts of the witness stands.
Battlefield/Omega - The battlefield and omega versions will be fairly identical to each other. The background will still include the judges bench and a court backdrop. The judge will sit in his stand and do nothing. The floor and platforms where applicable will be brown like the court floor
Cameos(Gimmick and Hazards included here)
The Prosecutor bench - Prosecutors opposed by Phoenix and co will appear at this bench. Some inclusions would be Winston Payne, Miles Edgeworth, Gadot, Franziska Von Karma, and Klavier Gavin. Prosecutors from games 5 and 6 may appear as well as well, I haven't played those yet so I don't know who they would be and don't want to look them up for spoilers sake. They may occasionally hit poses from their games aimed at the defense, which can cause damage and knockback to players. Edgeworth will shout "OBJECTION", which will appear as a speech bubble. Von Karma will use her whip, Gadot will throw his coffee cup, and Gavin will air guitar, causing sound waves that will pulse out from him. They can be influenced to do this by attacking them.
The Defense stand - The defense lawyers will appear here. Apollo Justice, Athena Cykes, Mia Fey, and Phoenix Wright himself(if not being used) will show up here. The judicial assistants, Maya Fey, Pearl Fey, Trucy Wright, and others I may not know about yet will be here as well. The defense will occasionally shout an OBJECTION, HOLD IT, or GOTCHA out towards the prosecution. If hit while doing this they will attempt to block the opposing bench from being able to damage players.
The judges bench - The judge will be present at his bench. He will be present and is interactable as well. After a period of time of the prosecution and defense being active the judge will bang his gavel and call for order in the court, which will stop both sides from doing anything for a bit. You can also trigger this by standing in front of the judges bench and performing a successful taunt.
The witness stand - Popular witnesses from the series will appear here. They will not be interactive. For spoiler sakes I won't list them right here. If leadership wishes to pick them out or if I need to add them later I can.
