Born on Mars and orphaned after his parents died in an apparent military coup, Akito's dream to become a cook stemmed from the quality of the raw food available. Though he has a nanomachine controller enabling him to pilot machinery, he refused to become a military pilot; his first time in an Aestevalis, a humanoid combat robot, was an accident, though he quickly showed capable piloting skill. Due to the lack of pilots on the Nadesico, Akito was officially made one for the duration of the tour of duty. A fan of the anime Gekiganger, his devotion to the series is rekindled by fellow pilot Gai Daigoji. Akito is romantically adored by nearly all the girls aboard the Nadesico, especially the ship's captain Yurika Misumaru, who he later proposes to and marries. Akito Tenkawa is voiced by Yūji Ueda in Japanese and Spike Spencer in English.
Yurika is the beautiful but ditzy captain of the Nadesico and childhood friend of Akito Tenkawa. Though he considers her crazy, Yurika has romantic feelings for him, and the two later get married. Yurika is shown to be very scatterbrained at times, misinterpreting comments made by others as words of inspiration and devotion, and forgetting or twisting events from her and Akito's childhood. Nonetheless, she is a very capable captain, and a constant source of cheerfulness and inspiration for the rest of the crew. Yurika is voiced by Houko Kuwashima in Japanese and Jennifer K. Earhart in English.
The "Electronic Fairy", she keeps the ship's computer (Omoikane) running and slowly bonds with it, asking it numerous questions about society and human interaction. Ruri is depicted as the youngest member of staff on board the Nadesico, the space battleship that the series revolves around. Despite this, she is often portrayed as being more intelligent than the rest of crew, and seen as something of a "child prodigy". Ruri is often shown disparaging the inane antics of her older co-workers, usually by use of her catchphrase "bunch of fools" (バカばっか,baka bakka?). According to her backstory, Ruri has a special affinity with computers due to genetic engineering, something that also affects her attitude towards others. She is occasionally referred to as "Ruriruri" by fellow bridge crewman Minato and Aestivalis pilot Hikaru. Ruri Hoshino is voiced by Omi Minami in Japanese and Kira Vincent-Davis in English.
According to Keiji Gotoh, the movie version of Ruri was the easiest character he ever designed, her concept "popping into his head right away". Dan Kanemitsu, the English translator for Martian Successor Nadesico, notes that Ruri's phrase of "baka bakka" was one of the hardest lines in the show to translate from its original Japanese form. The character of Ruri was unexpectedly a favourite, and became popular among fans as a depiction of the moe ideal. Because of Ruri's quiet, serious character and dead-pan expressions, she is often compared to Rei Ayanami from Neon Genesis Evangelion.Hiroki Azuma believes Ruri to be directly influenced by Rei.
Manga - Ruri is full captain of the Nadesico. She seems not much different but she is given almost all the attention rather than just half. The mirror copy of her is the same and acts completely the same along with the fact that she is also captain of her ship. Both Ruris seem to also have an internal problem and cough up blood when under extreme stress.
Born Jiro Yamada (an average name, similar to John Doe or John Smith in English), he insisted that Gai Daigoji was "the name that belongs to (his) soul", and angrily asserted his "true" name whenever someone used the "other" one. A rabid Gekiganger otaku, he was an official pilot and arrived three days ahead of schedule when he learned they would be piloting actual robots like in the anime. Fueled by his devotion to the show, Gai had a fierce intensity in and out of battle, and was angry and resentful towards Akito for being the first one to engage the enemy, stealing "(his) destiny", even though he had a broken leg and was unable to fight. The two were soon able to bond over Gekiganger, although Gai couldn't understand why Akito would rather be "a dumb cook" than a robot pilot. Although it was Gai's wish to die heroically in battle like one of the characters, he was unceremoniously shot and killed during an escape of prisoners held aboard the Nadesico; Akito took his death very hard, and devoted himself to Gai and the ideals of Gekiganger. In the Super Robot Wars series of video games, the player can save Gai by fulfilling certain conditions, and in Super Robot Wars W, he lives as part of the game's default story, to the point of even having a game exclusive timeskip transition for both him and his Aestevalis Custom so as to fit him into the Nadesico movie's plot. Gai Daigoji is voiced by Tomokazu Seki in Japanese and Brett Weaver in English.
Megumi Reinard is a former voice actress who did work for anime and animated commercials. She is recruited by Nergal to be the communications officer aboard the Nadesico. Megumi has no love for war and killing in general. This is why she has a lot in common with Akito Tenkawa, who only wants to be a cook, not a pilot/soldier. She is also Yurika Misumaru's main competition for Akito's affection, though she is not really worried since the captain is oblivious to just about everything. Megumi is the first to officially be classified as Akito's girlfriend, beginning around episode 4. Megumi Reinard is voiced by Naoko Takano in Japanese and Jenny Strader in English.
The first officer of the Nadesico, Jun has no small infatuation for Yurika, leaving a position in the Earth's military to join her crew and "look out for her". She is clueless of how he feels and considers him her "best friend", though the rest of the crew realize his feelings. A common running gag is Jun's misunderstanding of Yurika's special efforts, such as preparing food--he believes it is for him, but it always ends up being for Akito, with him being passed by. He has crush on Yurika. Jun Aoi is voiced by Kentarou Itou in Japanese and Mark X. Laskowski in English.
Developed the Nadesico 's Phase Transition system for Nergal on Mars before it was invaded; when the ship returned to the planet, she came aboard, stating that the surviving colonists refused to leave, believing the ship would soon be destroyed; however, an attack immediately afterwards forced the grounded Nadesico to raise its shields, crushing the underground colonists and leaving her the only survivor. She hosts the "Naze Nani Nadesico" segment as a technical consultant along with Ruri and Yurika in an attempt to teach the crew about the ship's workings, as a way of atoning for what happened.

Aestivalis pilot and, she escaped from the L2 space colony when it was destroyed by the Jovians, salvaging four Aestevalis suits and fellow pilot Izumi Maki. The most fiery and combative of the three, but a surprise attack from the enemy left her terrified and crying out for help from Akito; this was noted and would be mercilessly brought up by Izumi and Hikaru many times, to her great embarrassment. Over time, she began to accept her feelings for Akito, but for the most part refrained from public displays of affection. Ryoko Subaru is voiced by Chisa Yokoyama in Japanese and Tiffany Grant in English.

Aestivalis pilot and rabid Gekigangar III fangirl, she was ejected from the L2 colony in a capsule which crashed into the Nadesico; making her way through the air ducts, she was directly over Akito's room as he was watching a tragic episode of Gekiganger. Moved to tears, her wailing could be heard through the overhead vent, right before she fell out of it and onto him. She is a rabid Gekigangar III fan and one day wants to publish her own manga about the series with herself as the lead female, and two of the male leads in a shōnen-ai relationship. During Martian Successor Nadesico: The Prince of Darkness it is shown that Hikaru becomes an actual manga artist, but is overstressed due to her profession.

Nagare came into the picture after the Nadesico escaped from Mars; a skilled Aestivalis pilot, Nagare rescued Akito during battle as the latter was in a state of panic and unable to move. He was soon assigned to the Nadesico, bringing along Erina Won, who he had a mysterious relationship with.

Head chef on the Nadesico, Howmei is responsible for making sure everything gets cooked correctly, even if it involves teaching Akito about the variety of spices and flavourings available on Earth.

She is known as a great team player and an excellent pilot, but was killed in her first battle with the team. During production, she was unnamed, so she was referred to in-series as "Newbie" and "Seelie" (by Ryoko both times).

Itsuki Kazama is voiced by Houko Kuwashima in Japanese and Kelli Cousins in English.
