Dangan Man
- Translated Name: Bullet Man
- Serial Number: DMN. 001
- Year of Creation: 2052
- Mega Man's Acquired Weapon: Rock Vulcan
- Bass' Acquired Weapon: Forte Vulcan
- Weakness: Barrier Wind and Forte Cyclone
- Motto: A bullet can penetrate almost anything!
As his name implies, Dangan Man (or "Bullet Man") is a giant bullet. While some may question this design, this allows him to "fly" around the area towards his opponents, doing massive damage to them. Additionally, his body is incased in solid titanium, making him very difficult to damage. While not trying to crash into his opponents, his weapon, the Vulcan, can penetrate almost any type of body armor.
Konro Man
- Serial Number: DMN. 002
- Year of Creation: 2052
- Mega Man's Acquired Weapon: Flame Shower
- Bass' Acquired Weapon: Flame Mixer
- Weakness: Rock Buster and Bass Buster (Normal Weapon)
- Motto: I burn, therefore I am.
Konro Man was based on plans from a robot army of torch-like robots, but R-Shadow decided to make a fire-based robot instead. While, as his name implies, he is essentially like a giant stove, he proves to be a deadly fighter. His Flame Shower attack sends balls of fire raining down from the sky, while the Flame Mixer is a flame-thrower style attack that melts almost any opponent.
Aircon Man
- Serial Number: DMN. 003
- Year of Creation: 2052
- Mega Man's Acquired Weapon: Barrier Wind
- Bass' Acquired Weapon: Forte Cyclone
- Weakness: Flame Shower and Flame Mixer
- Motto: My weapon is far more fearful than my name!
Aircon Man (whose name is short for "Air Conditioner Man") was designed by Quint based on the design of Wind Man (Mega Man 6), who was built 39 years before R-Shadow's time. He stepped up the power of Aircon Man's fans, providing him with the ability to "blast" away his opponents with deadly cyclonic wind blasts and put up walls of wind to stop the attacks of his opponents.
Komusou Man
- Serial Number: DMN. 004
- Year of Creation: 2052
- Mega Man's Acquired Weapon: Doppler Crash
- Bass' Acquired Weapon: Doppler Attack
- Weakness: Flame Shower and Flame Mixer
- Motto: I fight through the old, deadly arts.
Komusou Man's design was based on that of that of the ancient Japanese monks. He has the ability to make doubles of himself with his Doppler Crash and Doppler Attack, and his martial arts, through the use of his staff/flute, conjures up magic-like attacks that prove deadly to his foes.
Clock Men
- Serial Number: DMN. 005
- Year of Creation: 2052
- Mega Man's Acquired Weapon: Time Switch
- Bass' Acquired Weapon: Time Bomb
- Weakness: Barrier Wind and Forte Cyclone
- Motto: Time doesn't wait for anyone.
R-Shadow decided to go with the age-old saying that "two heads are better than one" and built a duo of time-controlling robots known as the Clock Men. These robots have a time-stopping ability that was based on Flash Man's Time Stopper, called the Time Switch, but even without this power, their dual attacks make them deadly combatants against almost any foe!
Compass Man
- Serial Number: DMN. 006
- Year of Creation: 2052
- Weakness: Barrier Wind and Forte Cyclone
- Motto: I never get lost!
Like some of the other Dimensions, Compass Man's name might be deceiving, making him sound pathetic, but he is quite a powerful foe. R-Shadow designed him based on Dr. Wily's Sword Man (Mega Man 8), a robot whose body had two parts to it. Compass Man separates his torso from his legs and spins around the room, slicing at opponents with his deadly blade hands, while his legs will try to corner his "prey" and do even more damage.
R-Shadow
- Serial Number: RKN. 000
- Year of Creation: 2047
R-Shadow is the robot that created the Dimensions and traveled back from the mid-21st century (the year 2052) to attack Symphony City in the hopes of dueling and destroying Rock. Rock has no idea why this is the case, but when he confronts R-Shadow after defeating a few of his Robot Masters, he tells him that he is Rock from the future, "upgraded" by Dr. Wily and sent back on a mission to destroy his arch-enemy, Mega Man. In otherwords, he is Quint, a robot that Rock had faced and defeated five years ago.
Had Quint been embarrassed that he was so easily defeated, returned to his own time, and built up a powerful new army with the technology of his time and returned to crush Rock? This certainly seemed to be the case, but even if it wasn't, Rock knew that he couldn't take any chances with this "challenger from the future."
When he managed to defeat R-Shadow in a "duel to the death," his true nature was revealed...R-Shadow was not, in fact, Quint, but rather he was a prototype robot that Wily designed when experimenting with the technology present in the future. When Wily used the Time Sled to travel to the year 2047 and reprogram Rock into Quint, he first experimented with the technology of the time, the first product of which was him, a robot which Wily called R-Shadow. However, Wily decided that in the end he had no use for him and he was discarded. It was for this reason that he had come to the year 2016: he wanted to prove Dr. Wily wrong and show Rock that he was the superior robot, even if he was, in the end, only a "clone."
While the game depicts his "death" after his defeat at the hands of Mega Man and Bass, Dr. Light soon thereafter manages to repair him, and he is shown in a photograph with the team at Light Labs, sans helmet. He was most likely reprogrammed for two reasons: one because his programming was based on Dr. Wily's "evil" logic and because if he continued to desire Rock's destruction and was defeated a possible time paradox would exist.
