Hell Fighter 17 (ヘルファイター17ごう Heru Faitā Jū Nana-Gō) is a Machine Mutant created by the evil scientists Dr. Gero and Dr. Myuu while in Hell.

Hell Fighter 17 is essentially identical to Android 17 from the Android Saga.

While being a Machine Mutant, he bears only the Red Ribbon insignia and lacks the Machine Mutant's cross-hairs in his eyes.


Hell Fighter 17 acts similar to Android 17 during his time as a delinquent in the Android Saga, and also made Android 17 act like this when possessing him. However, different from Android 17, Hell Fighter 17 displays respect and loyalty towards Dr. Gero, referring to him with the honorific "sama" in the original Japanese version (though this trait is ultimately dropped after he becomes Super 17, partly due to Dr. Myuu making him loyal to him alone).

Hell Fighter 17 appearing in front of Vegeta

A joint effort between Dr. Gero and Dr. Myuu, Hell Fighter 17 was designed to locate his android counterpart Android 17 and fuse with him in order to become Super 17. He is the one who brainwashed and influenced the real Android 17 into attacking Trunks and his driver, and killing Krillin and the other people on the highway.

Hell Fighter 17 vs. Vegeta

When he arrives on Earth, before fusing with Android 17, he fights Vegeta in his base form and is promptly beaten. Vegeta is initially unimpressed with Hell Fighter 17's power until Dr. Myuu and Gero reveal that 17 is using only half of his strength. Followed closely by the Dragon Team, the true Android 17 arrives and the two merge into Super 17.

Hell Fighter 17 is the one in control of Super 17 due to having brainwashed Android 17 and thus the merged android is still evil. However Android 18 and Goku try to break through to Android 17 during the battle, eventually allowing him to hold Super 17 back, Super 17 finished off by Goku, eliminating Hell Fighter 17.



In the original Japanese version, Hell Fighter 17 is remarked by Vegeta to have "powered-up beyond belief" compared to the original Android 17 due to his ability to match Vegeta's base form.

In the Funimation dub, Dr. Myuu states that Hell Fighter 17 has equal power to the original Android 17. Hell Fighter 17 is shown to hold an advantage over a suppressed base Vegeta in battle, until he powers up, quickly overpowering 17. Myuu also notes that Hell Fighter 17 possesses half the power of Super 17, who in turn states that he is twice as strong as Android 17.

When in Villainous Mode, Hell Fighter 17 is able to fight against the Future Warrior in their brief battle, once after the empowered Machine Mutant had easily defeated Trunks with a single attack.

Super 17

The result of Hell Fighter 17's Fusion with Android 17 is the powerful Machine Mutant/Android hybrid, Super 17. Super 17 is much taller than both 17's with an athletic build. His hairstyle and clothing are slightly altered to give him a somewhat more mature appearance. His voice remains the same as Android 17, however. Hell Fighter 17's personality is dominant in the fusion, thanks to his brainwashing effect on Android 17. This form is powerful enough to fight Super Saiyan 4 Goku at the height of its power and possesses the ability to absorb energy through a special barrier.

Super 17 with Cell absorbed

While most media refers to Super 17 as the fusion of the two 17s, in Dragon Ball Heroes, it is said that Hell Fighter 17 possess the "Further Evolution" ability, which he uses to absorb Android 17 to become Super 17, and can then absorb Android 16 (or Android 19) and Cell to go even further, gaining the "perfect physical body".[2][3][4][5] Additionally, he can absorb Android 18 independantly to achieve an empowered form resembling a fusion of the two.

As part of the Ultra Pack 2 DLC in Xenoverse 2, in New Parallel Quest 144: "Super 17's Super Plan", Android 17 breaks free of Hell Fighter 17's control forcing him to seek to absorb Android 17 instead of fusing indicating that Hell Fighter 17 can resort to absorbing Android 17 to become Super 17.
