During its seven seasons on the air, the cast of The 100 evolved significantly. The initial core group - comprising the 100 delinquents plus their parents on the Ark - grew to include the Grounders, then shrank as they got involved in conflicts and died out. More and more tribes are introduced, including many men in positions of power and servitude.

Some are villainous, like Russell Lightbourne, while others turn out to be allies, like Jordan. Even those who have been part of the cast since the beginning change dramatically, like Bellamy and Murphy. Both of them have significant romantic storylines, but how would they pair off in the real world? Not everyone is who they seem on The 100, especially when it comes to romance.

Russell Lightbourne

The 100 Russell Lightbourne

Russell always has an agenda, and it's always an evil one. Even for someone who's willing to overlook Russell's moral shortcomings, he wouldn't make a great partner because he's so self-involved.

He'd never make time to care about someone else as much as cares about himself - and he always puts himself first. In fact, he's probably the kind of guy who'd kill off their significant other if he got too annoyed of them. Unless, of course, it would be a political or spiritual advantage to him.

Finn Collins

At first, Finn seems like a nice enough guy. He's got the whole cheeky bad boy thing going on, which, of course, good-girl Clarke falls for. However, in season 2, it becomes clear that Finn is easy to grow jealous and obsessive.

Care is always a good thing in relationships, but Finn takes it about twenty steps too far. He becomes violent, erratic, and overall impossible to deal with calmly. He's definitely one to avoid before things get too serious.

Jasper Jordan

Jasper is one of the characters who was gone too soon. He was sweet, sensitive, and innocent until he lost Maya. His first hint of romance comes early in the show when he's smitten with Octavia. This turns out to be only a brief flirtation and never leads anywhere, but he later has a more serious romantic relationship with Maya.

With Maya, Jasper is a fine partner and is ready to do anything for her, even kill someone. This might not be the best quality to look for in a partner since Jasper is abandoning his own character principles; he's ready to become a murderer for someone else. Jasper is also not quite as mature as his peers, which may not be ideal for a romantic partner.

Marcus Kane

Like many characters on the show, Marcus goes through his fair share of ordeals. He changes almost entirely in his values and core beliefs during his time on the series, which is clear in his relationship with Abby. At the start of the series, he never would have been with Abby - in fact, he was ready to kill her entire family.

He's a ruthless man when he's first introduced, and a little too strict. Over time, he softens and becomes more likable, but he seems always to have the greater good in mind, so he wouldn't have time to devote himself to romance. This might make him a good person, but not the best romantic partner.

John Murphy

Murphy is almost unrecognizable at the end of the series compared to who he is in the pilot. He shares a sweet, endearing romance with Emori, which proves that he's actually not a bad romantic partner.

However, it takes a lot of growth for Murphy to put anyone above himself. There's also the matter of his morals. By the end, he has his priorities sorted out, but that doesn't mean that, when presented with a certain situation, he wouldn't go back to his old ways.

Thelonius Jaha

The 100 Thelonius Jaha Woods

Jaha is arguably the best leader of all the characters in The 100, but he may not be the best romantic partner. He's so preoccupied with leading that he doesn't always have the time or mental capacity to prioritize his family.

Jaha is a bit of a mixed bag: he's very kind, but he's also killed hundreds of people. He's not always emotionally present because he's too preoccupied with being professional. He's mature and usually does the right thing, but sometimes at the expense of his loved ones.

Bellamy Blake

Bellamy is one of the most desired characters in the series, at least among the younger characters. Eventually, he gets his morals straight and becomes a character to be admired. He takes care of his sister, always stands by Clarke, and tries to enact peace.

However, when it comes to being in a committed relationship, Bellamy may not be the best choice. His tw0 onscreen girlfriends, Gina and Echo, have valid concerns for their relationships. Given the circumstances and the environment he lives in, it makes sense that Bellamy doesn't prioritize his relationships, but at times he seems to forget that he has a girlfriend altogether.

Lincoln

Lincoln In The 100 Season 2

Lincoln may seem terrifying at first, but that's mostly because viewers don't know what to expect from him. The truth is, he's quite a gentle, caring, nurturing being. He, of course, does have moments of violence and anger, which could be a reason to avoid him.

In his relationship with Octavia, he offers her a place of comfort and is someone she can talk to. They support each other and grow together. Their love survives against all odds, and Octavia grieves him for a long time after his death.

Monty Green

Monty has a gentle nature and always wants to do what's right, even when his friends don't. He has a dark past, just like everyone else on The 100, but he's trying to move past it to create a world of love and peace.

Monty is the one who saves the group over and over again, thanks to his logical and critical thinking, and his desire for love and light. He shares a sweet romance with Harper, is a great friend to Jasper, and makes big sacrifices for the greater good. He never puts himself first unless he knows it won't negatively impact others, and pushes Clarke to do better for the human race.

Eric Jackson

The 100 Eric Jackson Talks to Madi

Jackson is one of the least problematic characters in the show, which could be why he's so often overlooked. He rarely causes or even partakes in any conflict. He dedicates his life to helping and saving others, and even when he's not on duty, he's trying to look out for other people.

His relationship with Miller isn't the focus of the show at any time, but it's always there and always endearing. The two have nothing but love and care for each other, and they stick together through good times and bad. Jackson is just a nurturing, supportive, and emotionally present character who proves to be a great romantic partner.
