Roger and Dorothy (The Big O)
Cast In The Name Of God, Ye Not Guilty
The Big O is an anime known to both fans of Toonami and Adult Swim. The art deco aesthetics and story about a rich man, Roger, who fights crime on the side is reminiscent of the 90s Batman cartoon. The big difference is that Roger piloted a giant mech, Big O, which was referred to as a Megadeus in the series. In the first episode, Roger rescues a female android named Dorothy who talks in a monotone and often butts heads with Roger as she becomes a main character too. While the two never officially become a couple, it’s an unstated romance that is clear to the viewers that is both sweet and funny.

Jean and Melfina (Outlaw Star)
Falling In Love With A Ship
The romance in Outlaw Star is not as weird as the one between Joker and EDI in Mass Effect. That was between a man and an AI assistant that eventually gained a body. In Outlaw Star, Jean is a human bounty hunter and Melfina is an android imbued with the gift to integrate into a ship’s database.
She’s a bit lost in the world she inhabits and finds it hard to blend in with normal human behavior. Jean isn’t sure how to treat Melfina back, but the two slowly become closer by the end of this one-season anime that Cowboy Bebop fans would surely eat up if they somehow missed it up to this point.

Alita and Hugo (Battle Angel Alita)
Just A Girl And A Boy’s Head
Battle Angel Alita started as a manga but was adapted into a two-part OVA that left a lot on the table. In the OVA, Dr. Ido goes to a junkyard and finds the wreckage of a young robot girl. He restores and raises her as Alita. The story takes place in a future wherein most of humanity lives in slums with the rich towering above them in a floating city. Alita soon has dreams of becoming a hunter-warrior, a bounty hunter, to stop evil robots which is when she meets a young boy named Hugo.
The OVA skips through a lot but they fall in love and even share a kiss, but Hugo eventually gets killed. The only thing that survived was his head which Alita preserved, brought to Dr. Ido, and he turned Hugo into a cyborg. Unfortunately, Hugo still died after attempting to go up to the floating city, leaving the OVA on a dark note.

Hideki and Chi (Chobits)
If Computers Were Girls
- Director: Morio Asaka
- Studio: Madhouse
- Released: April 2, 2002 (Japan)
Anyone who grew up searching for manga or anime DVDs in the 2000s probably came across a copy of Chobits featuring a young girl with robotic ears. This is Chi, a computer in person form whom the main character, Hideki, finds one day. He teaches her about humanity and helps Chi explore her origins like why she was abandoned.
Like most Clamp stories, it’s focused purely on romance and comedy blended together to create some wacky and awkward situations. It’s a short watch and an even shorter read that mostly ends well between Hideki and Chi.

Time Twists The Knife
Terminator Zero is an anime adaptation of the property, taking place in Japan and focusing on a scientist, Malcolm, who has in invented an A.I. named Kokoro he hopes can stop Skynet.

The two fell in love but to save humanity, they had to travel back in time, erasing Misaki’s memory.
She became the nanny to their children, unbeknownst to her that she was a robot or the love of Malcom’s life. It’s complicated and messy like most relationships are with the added confusion of time travel.

Anime love stories are rarely “standard,” but these unconventional romances also end in tragedy, making them stand out even more.
Among these invaders is Android 18, the only female robot, who beats a majority of the fighters in combat. In classic Dragon Ball fashion though, eventually, enemies become allies as Android 18 hooks up with Krillin in later stories. It’s his first major girlfriend in the series leading him to mostly put fighting aside to instead focus on being a good husband and father to their child, Marron.

Gesicht and Helena (Pluto)
Netflix’s Greatest Anime Achievement
Pluto was a manga that retold the story of Astro Boy during one of his most fatal arcs. It was for a more mature audience, exploring what it means to be a robot in a human world. Twenty years after the manga debuted, Netflix finally helped adapt it into an anime which was met with near-universal praise. There are many love stories in the anime which is funny considering the overarching narrative is about a mysterious entity killing the world’s strongest robots who have mostly retired to raise families.
Gesicht is the main character who loves his wife Helena. It’s a mystery that looks at war, murder, lost memories, raising children, and so on. Anyone interested in the concept of robots should take a look at Pluto as it feels like the Rosetta Stone of manga/anime storytelling.
