The form is not documented in any version of the game's manual, seemingly intended as a secret for the player to discover.

As of the Special Edition however, it was officially referred to as his Sin Devil Trigger. When Dante finally faces Vergil in combat, the latter also possessed a more powerful Devil Form, which Nico speculated was a consequence of 'his time bein' Urizen'. In her report on Devil Sword Dante she states she isn't sure if Dante used his own powers or those inherent to Rebellion to create the new weapon. Nico's report on Sin Devil Trigger Dante states that there is 'no telling' how much power Dante has in this state, speculating that he may even be more powerful than Sparda himself. On confronting Urizen, he calls the Devil Sword Dante into existence in his hand, and thereafter adds it to his arsenal when in human form. By doing so he unlocks his true potential, a devil form powerful enough to confront the mighty Demon King. Through this he fuses the remains of Rebellion, the Devil Sword Sparda and possibly his own powers. Much to Griffon's horror, he decides to test this theory by thrusting the broken hilt of Rebellion into his stomach. He considers that, if Yamato is the sword that divides, Rebellion is perhaps the inverse. After V locates Dante and gives him Sparda, the demon hunter journeys to the ruins of his old family home.Д¬ontemplating a photograph of his family, Dante ponders why Sparda had given him the Rebellion, recalling how he had once awakened his potential when Vergil stabbed him through the chest with the sword. The color scheme of Vergil's Sin Devil Trigger is silver to blue color, opposite of his brother's.Дuring the incursion of the Qliphoth in Red Grave City, Dante is defeated by Urizen and the Rebellion's blade is shattered in the battle. The solid part of his body resembles a samurai armor more and whole body is wreathed in silver aura.

While the head basically shaped like his normal Devil Trigger form in Devil May Cry 4, Vergil's Sin Devil Trigger resembles a traditional samurai helmet more, with the horns assume hollowed and tube-like shape, venting demonic energy in a manner resembling exhausts. Vergil's Sin Devil Trigger has four wings folded down in a similar manner to the tails of Vergil's coat, blue arm-mounted blades, and a thick reptilian tail with a barbed tip that extends from between its shoulders. The solid parts of the body seem to be a combination of metal and black demonic stone: any areas of exposed 'skin' are covered in square scales. The chest and head glow with incandescent orange in a similar manner to Berial, and the whole body is wreathed in demonic flames.

It has two pairs of wings, and the horns on top of the head are now longer. In Devil May Cry 5, Dante's Sin Devil Trigger has a somewhat similar appearance. Dante wields a pair of bright red retractable spikes in his forearms, similar to the demonic needles used by Mundus. It is shown to have reptilian feet and four bat-like wings which are darker than the body. The head is surrounded by large ram-like horns with a second smaller set extending from the top. The Ultimate Devil Form's appearance in Devil May Cry 2 resembles Dante's previous transformation into Sparda, but more bestial.
