Zero's character was met with positive critical response by publications for video games.
Game Revolution called him "mysterious,
androgynous" and compared him to
Proto Man "with a ponytail". In retrospect,
DenfamincoGamer said the most likely explanation behind Zero's inclusion in the series his popular characters in the
Mega Man X series. In particular,
Mega Man X4, in which he was promoted to the second protagonist, delved into his past and inner struggles, and, coupled with the passionate performance of Okiayu, who solidified his popularity. Zero's differences with the original Mega Man and X helped making his character more unique leading to the creation of his own series. Jeese Scheeden from
IGN enjoyed his sword-wielding characters in the video games, describing him as an answer to the question of how Mega Man would fight if armed with a sword, and noted his fighting style as popular with gamers.
GameZone writer Michael Knutson praised the inclusion of Zero in the
Mega Man X series, citing his playability as popular amongst series fans as it expanded the gameplay.
GameSpot editors Christian Nutt and Justin Speer stated that
X3 benefited from the addition of Zero as a limited playable character as previous games from the franchise only used both Mega Man and X. In regards to Zero's powers,
Game Informer claimed Zero had the best weaponry in
X6 based on the multiple extra abilities he had before defeating any boss character. Jeremy Parish from
1UP.com stated that his appearance as a playable character with his own story in
Mega Man X4 by itself made it the best game in the
X series.
GameSpot noted the contrast in his gameplay to that of X in
Mega Man X4 increased the difficulty of using him in the title. Additionally, Brett Elston from
GamesRadar credited Zero as one of the reasons the
X series became so popular and that his own popularity within gamers earned him his own video game series.
GamesRadar also cited Zero's actors across the
X series, finding the first from
X4, Wayne Doster, unappealing due to his infamous scene where he yells in front of the dead Iris. On the other hand, the site praised Yong Bosch's take on the character, believing it was likable. While reviewing
Mega Man X: Command Mission,
1UP.com criticized that his English voice acting makes him "sound like a surfer" and lamented his poor screentime. By the time of
Mega Man X6,
Destructoid criticized Zero's role in the story as he had been killed twice ever since his debut and once again is revived. His closer relationship with X was also the subject of negative responses, comparing them to fanfictions.
IGN repeated their positive sentiments about Zero in their list of characters they wished to see appear in a future
Marvel vs. Capcom title, describing him as "arguably cooler than Mega Man", regardless of version in comparison.
PSM praised the character as well, stating "[he] might wear some funky shoes, but that doesn't stop him from kicking some robot butt". When compared with Zero, X was often seen as the less compelling character, with Zero being the more memorable of the two. His relationship with Iris has been regarded as that of a
star-crossed due to the tragic story of
Mega Man X4. In regards to his
Mega Man Zero incarnation,
GameSpot believed the character's redesign was well employed based on his presentation.
IGN considered Zero's retake be like a
breakout character due to how he develops his own skills unlike previous versions of the Mega Man cast.
Destructoid simply described Zero as "a red death machine who uses pistols, lightsabers, shields, and multiple other melee weapons..." due to his dark characterization when compared with previous main characters. Nevertheless,
Nintendo Life noticed that across Zero's spin-off, the title Reploid continuously showed a
character arc that would make him more likable to gamers, earning the spotlight for the first time based on how he was originally a side character. Similarly,
US Gamer referred to Zero to have one of the more elaborated story arcs in the
Mega Man franchise in general due to how he changes between the
X series and the
Mega Man Zero. The writer further added that the apparent misrelationship between Zero and X before the revelation that the latter was a clone gone corrupted was one of the darkest things seen in Capcom's games due to the idea of Zero working to kill X, the former protagonist of the series. Joel Couture from
DeadXP said that while
Mega Man X offered a far darker narrative than original Capcom franchise,
Mega Man Zero tests the player's morale by giving them power ups to Zero but in the form of Cyber-Elves composed of child-like robots rather than X's armors that show no life. Zero's connections with the original
Mega Man characters have been the subject of speculations within fans. As it is believed that Dr. Wily created Zero in the image of Protoman or the possibility that he was responsible for multiple deaths offscreen as it is unknown what happened to the original
Mega Man cast, explaining their absence in the
X storyline. In 2018, Capcom left clues about how Wily dies when creating Zero but the idea of Zero killing the
Mega Man characters was negated.
GamesRadar regarded both X and Zero "crossover veterans" based on their multiple appearances and looked forward to their team up in
Project X Zone where the duo teamed up for the first time in a crossover.
Game Informer considered X and Zero as one of his favorite characters in gaming, and thus wanted to play as them in
Project X Zone 2. In a comparison of the three main characters from
Mega Man X8, Luthfie Arguby Purnomo from
Studies on Shift noted that X's weapons symbolized his status as a cultural hybrid in contrast to the
Western Axl and the
Eastern Zero. ==Footnotes==
