"Has my power, the "Explosion" Septima... ever been useful? It hasn't! What crap!"
Viper, Justice Rage

Viper, "The Burning Wrath", also known in Japan as "Burn Thrust", Daytona [1] (怒れる爆炎 (バーントラース)デイトナ, baan toraasu Deitona; Burn Thrust translating to "Angered Explosion") is a member of The Sumeragi Seven, a group of Adepts whom serve under Nova, and an antagonist in Azure Striker Gunvolt.

Once the former leader of a notorious gang, he became infatuated with Lumen after hearing one of her songs and promptly joined Sumeragi. He has an affinity for the Explosion Septima, which allows him to manipulate fire.

English Website DescriptionEdit

Viper is an Adept who keeps watch over Sumeragi’s chemical plant complex. His Septimal power, known as Explosion, gives him the ability to compress a large amount of thermal energy into small spheres that explode on impact. He can also engulf his body in flames to deliver extremely deadly attacks.

Viper was once a notorious gang leader, but once he became infatuated with Lumen’s voice, he quickly found himself signing up for Sumeragi’s private army. The Glaive which holds his septimal power is called the Lord of Fire. [2]

Appearance Edit

Viper is a teenage boy with red eyes and long, spiky red hair, tied up in a ponytail. He wears a black Sumeragi officers jacket with gold highlights, and a white vest underneath that. He wears checkered cargo pants and black boots. He also wears silver earrings. In various artwork for Justice Rage, Viper is depicted wearing a dark red jacket.

In his Weaponized form, Viper gains black eyes with red irises, and his hair turns a much brighter orange. He wears red and black armour with white highlights, white gloves and a single red horn-like spike on his forehead. Attached to his lower back are guns which can double as hind legs.

Personality Edit

Representing the sin wrath, Viper is hot-headed, loud, and vulgar. His most notable attributes are his incredibly short temper and highly defensive attitude, the slightest tease able to send him into a whirlwind of fury. Once, he savagely beat one of his own gang members for making fun of him. He is also very impulsive, something Nova takes advantage of to manipulate him into doing odd jobs.

However, when he isn't consumed by rage, Viper can be surprisingly calm and aloof, showing a general interest in nothing in particular and is very dismissive about everything in general. It's revealed in Justice Rage that Viper generally dislikes his Septima, calling it meaningless, and saying he never asked for it.

He also holds some resentment against society, feeling discriminated against due to his Septima, and fully acknowledging people only follow him out of fear, and often feels a general "emptiness".

Viper is also extremely infatuated with Joule, her being the sole reason he joined the Sumeragi Group, saying she is "cute" hooked up to machines, and that her song was the only thing to inspire true passion within his heart.

In exchange for his allegiance to Sumeragi, Nova promised to give her to him after Project Muse was completed. When she is captured by Gunvolt, Viper seemed to develop a personal vendetta against the Adept. When fighting him, he flew into a murderous rage bordering on outright insanity, constantly screaming about how he was going to kill him.

Plot Role  Edit

Other AppearancesEdit

Azure Striker Gunvolt 2Edit

Viper appears as a DLC boss in Azure Striker Gunvolt 2, along with the rest of the Swordsmen, serving as the boss of the Isle of Dreams. He has the same attacks as in the first game.

Mighty GunvoltEdit

Viper is featured as a boss in the 8-bit spin-off as the boss of the Biochem Plant once more. His attacks are similar to his ones from the original game.

Powers and Abilities Edit

As a human attuned to the Septimal stage of the Lifewave, Viper is a powerful Adept who wields the Explosion Septima, which, true to its name, allows him to manipulate fire, usually by compressing thermal energy into fireballs.

While initially untrained with his powers, upon gaining a Glaive, Viper's powers have become strong enough that he can compress enormous amounts of thermal energy into spheres of heat called "Angry Bombs" that cause powerful explosions on impact. Viper's Septima also gives him resistance to fire as shown in his Refulgence Special Skill where he jumps through the fire pillars and gathers heat around himself with no ill effects.

Due to all his time spent fighting other gang members before joining Sumeragi, Viper is a formidable opponent. Viper can engulf his body in flames to bolster the strength of his physical attacks, usually done to enhance the strength of his kicks. Viper is also very agile, often leaping across the screen with great ease, even using his powers to create a platform of heated air that he can kick off of to change his airborne movements.

In his armored form, Viper mainly fights with his waist mounted guns, using them to fire his Angry Bombs. The guns can also unfold into a pair of robotic hind legs to enhance his agility.

Skills Edit

The boss fight with Viper is unique in that fire pillars stand at the sides of the screen, restricting movement within the boss arena as well as providing arena hazards for Gunvolt.

Slide Edit


Viper's standard attack. Viper performs a quick sliding kick across the floor towards Gunvolt.

  • At battle phase one, Viper may perform two slides consecutively. Beginning with battle phase two, Viper no longer performs consecutive slides.
  • Viper will always follow-up this attack with his angry bombs or his unicorn drop. [3]
Angry Bombs Edit

アングリーボム、Angry Bomb

Viper's standard attack. Viper fires three explosives in an upward arc.

  • The explosives can be detonated if they come into contact with Gunvolt's Flashfield or if Gunvolt shoots them with his bolt; the explosives leave lingering explosions in the spot where they were detonated.
  • Viper will not proceed to his next attack until lingering explosions have dissipated. [3]
Unicorn Drop Edit


Viper begins using this attack at battle phase two onward. Viper first jumps towards the fire pillar farthest from him. He then performs a wall-kick towards the other fire pillar, shooting a three-way set of angry bombs towards the ground while he is mid-air. He performs a second wall-kick once he reaches the second pillar, shooting a two-way set of angry bombs towards the floor while he is mid-air. At the conclusion of this attack, Viper will perform a third wall-kick towards Gunvolt and kick him.

  • Viper may follow-up or interrupt this attack with his volcanic axe attack or feint assault.
  • If Gunvolt is in the way of any of Viper's jumps / wall-kicks, then Viper will kick him into a fire pillar and cancel this attack. [3]
Volcanic Axe Edit

ボルケーノアックス、Volcano Axe

Viper begins using this attack at battle phase two onward. Viper performs this attack as a follow-up or cancel to his unicorn drop. When Viper wall-kicks towards the ceiling in his unicorn drop attack sequence, he will disappear momentarily before performing a drop kick on Gunvolt. The drop kick's impact on the ground causes two bits of fiery debris to rise and fall on either side of Viper.

Feint Assault Edit


Viper begins using this attack at battle phase two onward. Viper performs this attack as a follow-up or cancel to his unicorn drop. When Viper reaches a fire pillar at any time during his unicorn drop attack sequence, he may jump towards Gunvolt and fire a three-way shot at him.

Refulgence Edit

サンシャインノヴァ、Sunshine Nova

"Rays of searing heat / The sun returns all to ash / Beneath its wrathful gaze! Refulgence!"

Viper's special attack. Viper performs wall-kicks across the fire pillars until he reaches the top of the screen; whenever Viper makes contact with a fire pillar, two bits of fiery debris will drop onto the floor. He then fires several dozens of slow-moving fiery shots that radiate outward. He then proceeds to oscillate side-to-side in the air, firing slow-moving waves of three-way and two-way shots.

Quotes Edit

"You're telln' me to step back, Gunvolt? When I heard you were here in my turf, I busted my tail to get down here. Forget about the reactor, the only place you're goin' is 6 feet under! The name's Viper. I got a real bone to pick with you for snatching my love, Joule, from me!"
Viper , confronting Gunvolt

"Duh! Are you braindead?! I was gonna make my move... Then you snatched her away from me! Unforgivable!"
Viper , fighting Gunvolt

"Hah! You're a filthy terrorist, so you should already know this! The world is an awful place for punks like us, for Adepts. Sumeragi shielded Joule from all the dangers of the world. Let me tell ya, she may've not been stoked about all this... That's how things are for idols. It's just part of the job. Nobody gave you the right to decide what is best for her!!"
Viper , giving his opinion on Joule's life

"Shut up! Just, shut up! She's so cute all hooked up to that machine! Feels good, man! But you stole my bae, and my personal utopia along with her! It's unforgivable! I'll bury your sorry hide!!"
Viper , raging over the loss of his fantasy

"Hey Gunvolt, you didn't think I was though with you, did you?! Now it's finally my turn!! The fires of Hell feel lukewarm compared to my flames now... Joule is mine, punk! I'll never hand her over to you again! This time around, I'm gonna kick your stupid face into the ground!"
Viper , after his resurrection

"Once I wipe you out for good, Joule will be all mine, got it?! I heard it straight from the top brass! When it comes to Joule. They'll leave everything to me!"
Viper , stating his claim on Joule

"SHUT UP! My... raging flames will turn you to ashes, GUNVOLT!!"
Viper , raging even more


  • Viper's design is based on a centaur as seen in his concept art for Azure Striker Gunvolt. His hind legs double as boosters that can fire explosives.
