Quint

Quint (クイント) is a robot that battles Mega Man in Mega Man II. His main weapon is Sakugarne, a digging machine that looks like a combination of a pogo-stick and jackhammer.

Contrary to popular belief, Quint is not a Mega Man Killer. He is often mistaken for one because he is an extra Wily stages boss from the Game Boy games like the Mega Man Killers (Enker, Punk and Ballade), and the four appear in the same stage in Mega Man V.

Quint should also be not be mistaken for Rockman Shadow from Rockman and Forte: Mirai Kara no Chousensha, who was created at the same time period as Quint and is similar to him, and uses a weapon similar to Sakugarne. The game is also not considered canon to the mainstream games, while Mega Man II, the game Quint was introduced in, is.

History
There is a discrepancy as to who Quint really is. According to Rockman and Forte, Quint is merely a creation of Dr. Wily's from the use of future technology he obtained by using the Time Skimmer, an experimental time traveling mechanism he stole from the Chronos Institute.

The english translated version of the video game, Mega Man and Bass, provides Quint with a different origin, with Wily traveling into the future to kidnap a disarmed Mega Man, only to reprogram him into Quint.

Wily arms Quint with the Sakugarne, a jackhammer-type weapon that turns ground fragments it digs up into deadly projectiles. Mega Man fights against Quint during the events of Mega Man II, and Quint escapes after the battle. Mega Man faces him again inside the Wily Star in Mega Man V, but it's unknown if that's the original Quint or a copy, as several inactive copies of him and the Mega Man Killers can be seen in the Wily Star.

Rockman and Forte: Mirai Kara no Chousensha seems to hint that both of Quint's origins described above hold merit, as there are "two" Quints- one actually built by Wily and another who is really a reprogramed Mega Man. However, seeing as the video game was only licensed by Capcom, its canonicity is disputed.

Quint also appeared as a card in the game RockBoard, where he uses Sakugarne to modify one of the opponent's buildings.

Trivia

 * "Quint" is a play off of the musical term "Quintet."
 * In the American and European instruction manuals, it's said Wily traveled 37.426 years into the future (mid-21st century) with the Time Skipper, where Mega Man was living in peace. However, Mega Man's kidnapping and taking back to the "present" could be an explanation for why he is absent in the future (if Quint is, in fact, Mega Man). The time Wily traveled is sometimes confused as 37 years or 37426 years because of the decimal separator, but the latter is inaccurate as it's beyond later series like Mega Man X, and it's unlikely Mega Man would still be active after this time.
