Hell Fighter 17
Hell Fighter 17 (１７ Heru Faitā Jū Nana-Gō) is a Machine Mutant created by the evil scientists Dr. Gero and Dr. Myuu while in Hell to fulfill their mutual vendetta. His sole purpose was to locate the original Android 17 and fuse with him to take his true, ultimate form - Super 17.
Name: Hell Fighter 17
Origin: Dragon Ball GT
Age: A few Days
Gender: Male
Species: Machine Mutant
Appearance
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.
Personality
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).
Biography
Dragon Ball GT
Super 17 Saga
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.
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.
