Quint

Quint (クイント) is Mega Man from a peaceful future that was modified by Dr. Wily to fight against Mega Man in the present in Mega Man II. His main weapon is Sakugarne, a digging robot that looks like a combination of a pogo-stick and jackhammer.

Although Quint serves the same role as the Mega Man Killers (Enker, Punk and Ballade) in the Game Boy games, and the four appear in the same stage in Mega Man V, Quint is not part of the Mega Man Killers.

Quint should also be not be mistaken for Rockman Shadow from the game Rockman & 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.

History
Tired of being defeated, Dr. Wily stole an experimental time traveling machine (named the Time Skimmer in the American manual, and said to be from the Chronos Institute) to travel into the future and capture Mega Man. The future was peaceful as Wily had reformed and Mega Man, no longer needing weapons, had been remodeled back into a household robot. Recognizing this chance, Wily manages to convince his future self to abduct the now defenseless Mega Man. The future Mega Man was then reprogrammed and modified into the fighting robot Quint. With Mega Man himself on his side, Wily believed that he could not be defeated.

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. It's unknown if the Quint fought in the Wily Star was the original Quint or a copy, as several inactive copies of him and the Mega Man Killers can be seen in the Wily Star.

Quint also appeared as a card in the game RockBoard, where he uses Sakugarne to modify one of the opponent's buildings, and he has a cameo appearance in a flashback image of Mega Man II in Rockman & Forte: Mirai Kara no Chousensha.

Mega Man II
Quint attacks with Sakugarne, a jackhammer-type robot that turns ground fragments it digs up into deadly projectiles. He has a very simple pattern, attempting to hop on Mega Man and briefly churning up fragments around him, then repeating the process. His weaknesses is the Hard Knuckle. It will defeat him in six shots.

Mega Man V
Quint attacks just as he did in Mega Man II, but his weakness is now the Photon Missile. It defeats him in seven shots.

Mega Man (Archie Comics)
When Mega Man travels in time in issue 20, Quint appears in both the Mega Man II and Rockman & Forte: Mirai Kara no Chousensha events. Due to how brief his second encounter was, it is unknown if it was Quint or Rockman Shadow due to their similarities. Mega Man believed the second one to be the same person from the first encounter.

During the crossover Worlds Collide, Quint has a cameo appearance in issue 27 playing cards with Big the Cat.

Quint appears again in issue 55 in Dr. Light's tachyon-induced visions of the future. He is first seen fighting Mega Man in front of the Chronos Institute. Dr. Light initially assumes him to be a Copy Robot, but finds Quint to be "more... familiar than that..." Later, Dr. Light sees a vision of Dr. Wily allying with his future self and turning Mega Man into Quint.

Other appearances
Quint appears in the Rockman World 2 manga, and in CapYon.

Trivia

 * "Quint" is a play off of the musical term "Quintet".
 * Quint is red and white on the American and European box covers of Mega Man II.
 * Quint was referred to as "Quintet" on page 48 of Nintendo Power #34's Mega Man II article.
 * Quint's dislike of himself in his English Mega Man and Bass CD bio might be referring to the Mega Man of the present time. The Japanese version also mentioned that his dislike was of time paradoxes.
 * In the American and European instruction manuals, it's said Wily traveled 37.426 years into the future (mid-21st century) with the Time Skimmer, 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.
 * .426 of a year roughly means 156 days.
 * Though it may seem destined for Mega Man to become Quint and meet a poetic demise in battle against himself, this future represents only a possibility. As changes from the past ripple onward into the future, so too might the present stray from this set path.
 * In the Mega Man Megamix manga by Hitoshi Ariga, Quint's serial number is listed as SVN.001 or "Special Variation Number." He is the only known robot in the franchise to be given an "SVN" number.
 * In the Robot Master Field Guide, Quint is listed as being DLN-001, likely due to him being a future version of Mega Man who is also DLN-001.
 * Curiously, if Quint were to be successful in defeating Mega Man, he would never exist in the first place, and such would never defeat Mega Man, causing a time paradox.
 * Basically, Quint will die because Mega Man kills him in Mega Man V. However, he died in a Time Paradox (getting revived for a battle during 20XX), presenting that he will get revived. However, it could also be that he was a clone on the Wily Star, as several copies of him can be seen in the rooms before him, as well as the other Mega Man killers.
 * Quint has 32 HP in Mega Man II, which is unusual for a boss in the classic series games, with 32 HP being typical with most Maverick bosses in the Mega Man X series, whereas bosses in the classic series tend to have 28 HP in the console games, 19 HP in the Game Boy games, and 40 HP in Mega Man 8.
 * Quint's fight in Mega Man II is one of the few major bosses in the classic series to lack a visible health bar or even boss music.
 * In Mega Man, the two timelines show to the Mega Man X series, and the Mega man II. This may cause confusion as Dr. Light is building X, and the other showing Dr. Wily building Quint. The panel is a bit misleading, as X is a different creation.
