- Not to be confused with the real Sephiroth.
The false Sephiroth was a minor character in the SMG4 series.
When Francis was confronted by Mario, Luigi, Tari, SMG4, Fishy Boopkins, SMG4 and Saiko, he brought to life the anime character Sephiroth and had him to fight them with him. He easily defeated most of them, until he saw Desti with Inkweaver. He started to attack her, but Saiko managed to create a distraction with the help of Tari, and they attacked him until he died. However, Francis got the time to bring another Sephiroth to life, and the Sephiroth proceeds to kill Desti. After Sephiroth killed Desti, Francis created about 100 Sephiroths and started to attack the gang. When all hope was gone, Bob Bobowski, Swagmaster6969696969 and Chris break in with a tank and kill all replicas of Sephiroth.
In the alternate timeline shown in SMG4: WHAT IF...?, Desti managed to dodge his Masamune and False Sepiroth was knocked by Saiko's hammer into another room.
After an alternate Season 9 and Meggy's Destiny, Desti and Meggy are found bantering on a rooftop about their Splatfest win when, out of nowhere, Meggy is impaled by False Sepiroth with the same Masamune that almost killed Desti nearly a year earlier. This horrifies Desti, and she ends up hunting False Sepiroth down, with the two finally meeting in a dark city, Desti seeking vengeance, and False Sepiroth seeking to finish the job.

- While this Sephiroth is a replica created by Francis, the real Sephiroth made a cameo in ♫ The Ultimate Smash Bros ♫ and had a major role in SMG4: Nintendo Gets Deleted.
- Despite being a minor character, False Sephiroth has become one of the most infamous SMG4 characters, due to his murder of Desti.
- The way Sephiroth killed Desti mirrors how he killed Aerith Gainsborough in Final Fantasy VII.
