Boomer ( Former Boyfriend)
Nina and Boomer are technically boyfriend and girlfriend. They became a couple in Slade Strikes Back after Nina helped Boomer escape. She came along with him for many adventures. In The Great Time Travel Adventure their relationship became strained and they broke up since Nina grew jealously towards Lizbeth as part of Boomer's developing crush on her. But they settled things together, with Liz's help. Nina and Boomer are like brains and brawn in fighting and she does have some inferior with strength considering she can't fight which is a reason she is insecure with Lizbeth being a genius and a fighter. She is more grounded than her dumb friend, as she is far more prone to be sane despite her jealously issues. When Boomer gets annoying or sexist to Nina, Nina brings up his incident with Lizbeth where Liz broke his arm and leg by accident in seven seconds just to prove girls are just as good as boys but Boomer knows that girls can be as good as boys. Nina though occasionally wonders about Boomer and his brothers on how they are brothers as they are very different from him. When Nina learns of what happened to Boomer's brothers, she is going to threaten to kick Discord's ass 3 ways through Sunday
Nina and Boomer break up for good after Boomer's antics leave her humiliated at her graduation. Despite her great anger at Boomer, she stills feels bad for him which she reveals to Lizbeth. Nina learns Lizbeth likes Boomer and has for some time after Milo's death, Nina encourages her to go after him as she senses the deep bond between the two.
Bender (One of her two Bosses)
Nina is good friends with Bender who was also her boss in The V Team Island Adventure while she isn't as close to him as some of the others. She does trust him considerably
Bubbles (Great friends)
Nina is Bubbles' favorite girl to be with since they share so many common interests and love talking about Dib and Boomer. Both are feminine and girly and can understand each other well. Bubbles was the first person who figured out why Nina dumped Boomer since Nina felt comfortable telling her
Dib (Great friends)
Like Bender, Nina's relationship to Dib isn't fairy shown but she does care about and like him like a friend
Eddy and The V team (Former member of the group)
After Boomer, Lizbeth is the person Nina has the most time with. Lizbeth is Nina's best friend and confidante, Nina and Lizbeth both work well together and have shown capability for a great partnership. Nina and Lizbeth do have some contrasting personalities though, Nina is a girly feminine girl with boys, shopping etc on her mind while Lizbeth is a tomboy and has adventures, studies etc on her mind. The latter is even addressed on a snowy day when Nina gets a extreme makeover for her date with Boomer, when Lizbeth thought she overdid it. Nina has some inferiority issues towards Lizbeth feeling weak to her, as her best friend became tougher and more proactive than her. Nina also has some jealously towards her considering Boomer's feeling for her and thought Lizbeth was going to steal Boomer from her. Nina reconciled with Boomer and Lizbeth however, Nina decides to take the summer to be with her best friend and boy friend. Nina was surprised that she left for something, and Nina hopes she'll come back soon. Now the two are going to travel to the North Pole together to find Santa and learn Christmas' truth. She is very different from her yet quite similar.
Nina's jealously of Lizbeth faded in the future as she began to realize Lizbeth and Boomer needed each other as both of them were depressed what with Milo's death and Nina breaking up with Boomer. Nina and Milo encouraged her to go for Boomer and Nina was happy to see Boomer not be depressed since she still wants to be his friend.
While Nina may be the girly girl to Lizbeth's tomboy, Nina has short boyish hair while Lizbeth has waist length hair. Nina is hot headed and aggressive as Lizbeth being more calm and assertive. Though Nina is more interested in feminine fashions than Liz who hangs with males as opposed to her hanging with girls.
