Rosanov (ロザノフ Rozanofu?) is a character from Street Fighter Alpha: The Animation and one of the main antagonists of the anime. He serves as a very dangerous foe, but only as Sadler's puppet through which he learns the "Dark Hado" (Satsui no Hado).
His English voice actor, Tom Wyner, previously voiced Bison in Street Fighter II: The Animated Movie.
Rosanov is a cyborg created by Sadler that bears a slight resemblance to Hugo, with long gray hair and pupil-less eyes, his left one containing a green camera lens that records data. He is always seen grinning (even when destroyed) and is dressed in a black coat, grey trousers, and what appear to be fur boots.
After being repaired/rebuilt, he appears with shorter hair which flares off in two directions from several bandages wrapped around his face. Occasionally, Shun protrudes from his body, restrained by several molds of flesh.
Rosanov is a cyborg developed by Professor Sadler in order to collect the data of the strongest fighters in the world in a closed tournament. After detecting the immense energy of the Dark Hado from Ryu and Shun from their confrontation with Zangief, Rosanov is deployed to fight them in order to record battle data. Ryu and Chun-Li try holding him off but their attacks are easily thwarted, sending back their energy attacks with a wave of his hand. Rosanov aims a shot at Ryu, only for Shun to step in between them to take the hit. Shun's unconsciousness provokes Ryu's Dark Hado. Sensing the power increase, Rosanov blasts off his coat to begin the real battle and records the Dark Hado's energy firing off his own blasts to kill Ryu. However, Ryu dodges all of his shots while advancing toward him with a charging Hadoken. Ryu manages to close the gap between the two, Rosanov preparing to take the hit while recording him. He is then destroyed when Ryu plunges the Hadoken into his abdomen, utterly obliterating his body from within.
Following his first defeat against Ryu, Rosanov reappears at Professor Sadler's laboratory covered in bandages, acting as the island's guard. He first shows up when Ken and Chun-Li rescue Birdie from experimentation after his victory over Dan. He displays a far more intense fighting style and power increase, quickly subduing Ken and Chun-Li and brutally injuring Birdie in the process. He corners both Chun-Li and Ken, but Ryu steps in to fight. However, his attacks are ineffective. Using this opportunity to record more data on the Dark Hado by provoking Ryu to tap into this power. To accomplish this, he reveals the source of his newfound power: Shun was placed inside of his body, using him to directly tap into his power to unleash the Dark Hado. He speaks through Shun's voice and body to goad him into giving into the Dark Hado whilst taunting him and revealing that Shun was never his brother. Though angered, Ryu resists the urge and instead fights him with his own power, occasionally firing off Hadoukens. Unbeknownst to Ryu, the real purpose of this fight is for a now-plugged-in Sadler to absorb his power to make his body stronger by filling it up entirely with Dark Hado energy. He gives him one last chance to kill him, the only way he can do so is to fire off another Dark Hado. He forms one of his own and shoots it at Ken, who was lying on the ground. He prepares to finish him off this time, but Chun-Li rushes into save him, with Rosanov shrugging off her attack and shoves her head into the pavement, knocking her unconscious again. Ken recovers again and briefly breaks his vow to not kill to end Rosanov's life with a powerful Shoryuken. However, the attack exhausts Ken of his stamina and only succeeds in dislocating his jaw, which he effort snaps back into place. With both of Ryu's friends beaten badly in front of him, the Dark Hado awakens in him again and both prepare a Hadoken to fire at each other. Ryu's however proves to be too much for Rosanov, overwhelming his own blast and punching a large hole through his body while freeing Shun in the process. Rosanov crumbles to the ground with his grin still in his face, his mission accomplished as Sadler appears behind him after achieving the maximum amount of energy and data he needed.
Rosanov has no distinct style, relying on his incredible damage resistance to grab his opponent when they attack him to perform deadly, life-threatening attacks while attacking them from a distance with black and green energy blasts shot from his palm.
After taking Shun into his body, he displays incredible speed, practically gliding over the ground as he dashes towards his opponents. He also has access to Shun's Dark Hado, which allows him to fire off a Hadoken. He also displays the ability to fire an energy blast from his mouth.
