During the course of her long journey Alita has formed relationships with numerous other characters, both allies and adversaries.
The relationship began with Daisuke Ido acting as a father figure to Alita, who he discovered and revived after she had lain dormant for centuries near what would become the Scrapyard. Things changed however after Alita saved Ido from the mutant woman and began to recover her lost memories. This resulted in a severe disagreement between them as Alita realised that she could uncover more of her past through combat by becoming a hunter-warrior. However Ido came to grips with the situation and decided to let Alita live her own life and the two reconciled.
When it looked like that Ido died Alita suffered endorphin withdrawal, blamed Nova and his subordinates and would have killed them in a fit of rage if it wasn't for the restorer nanobots that nova injected them with. Also, Alita allowed Nova to leave because he promised that he can revive Ido and the reason she agreed to work for Tipharean was to find Ido.
When Alita finally found Ido she was shocked that he doesn't remember. After seeing the message that was made by Ido before he erased his memory Alita was so sad to see him in pain. However, Alita decided to leave him live in peace. After learning the secret of Tipharean Alita stated that it didn't made a difference as for her Ido is Ido and nothing would have changed that.
The first man that Alita fell in love with was Hugo and she felt an attraction to him from the beginning. However she felt a great deal of uncertainty over how he felt about her as a cyborg and was hesitant about learning how he truly felt about her. Hugo's focus on reaching Tiphares blinded him to the attention that Alita was paying to him, but after learning about his dream, she eagerly decided to help.
