So what if the mobile game, Fire Emblem Heroes teased new fighters around the time that super smash bros ultimate hasn't been released yet in this year? Let's find out within each event that is close with smash bros.
On March 7th, 2018, Smash Ultimate is announced but the title hasn't been revealed yet but before that, in a day ago, a FEH event is announced to come with Leif in this April soon, then in April Leif's Japanese voice actor was revealed to be Simon's Japanese voice actor used in Castlevania judgement, and later in May 26th, Vergeben leaked Simon and then he was annouced in August with a completely different Japanese voice actor, maybe that could probably be a rejected voice actor for Simon but there's more.
On June 19th, 2018, just after Smash Ultimate's title is annouced at E3, another event named Summer's Arrival, annouced Summer variation of Innes, he shares the same artist and Japanese and English voice actor as Joker from Persona 5, but this event is the only one to be released after E3, which is why Sakurai stated that the Smash Ultimate team had a hard time calling up Joker's voice actor which was likely to be his Japanese voice actor.
On August 7th, 2018, a day before the august direct annouced Simon Belmont as a playable in smash, A Festival in Hoshido event was annouced in FEH and the first unit to be shown is Xander: Dancing Knight, which he shares the Japanese voice of Lloyd Irving, which makes sense because playing as Mii Swordfighter in Century Smash can cause a save data corruption glitch to certain kinds of SD cards and the Mii Swordfighter's Airborne Assault, Power Thrust and Blurring Blade moves are a close approximation to Lloyd's Tempest, Sonic Thrust (Rising Falcon in the air) and Sword Rain moves.
On September 5th, 2018, a day before the direct was delayed because of that earthquake, a event named Doorway to Destiny is announced with Quan, he shares the same Japanese voice actor with Zack Fair but he can't be in smash, BUT, could he be the Japanese voice actor of Edrick, but what about his female alt?
On October 29th, 2018, days before the direct announced the final base roster characters and the DLC pack, and it annouced a lengundary version of Erika, which her Japanese voice actor shares the same voice actor as Navi but we know that Navi won't be in as a fighter, BUT, could she be the Japanese voice actor of Edrick's female alt?
Seeing as this happened in only one year, could it mean that one or two of the next two fighters could be voiced by a completely different but non-japanese voice actor or none at all?
