It's not easy staying optimistic in the DC Universe when you got villains like Scarecrow, Darkseid, and Parallax putting a damper on everyone's mood. Thank goodness that Starfire is around to brighten up every room she enters. Despite having a traumatic upbringing that should have made her as gloomy as Raven, Koriandr always looks on the bright side of life.

While most people assume she's just a ditzy alien, she is smarter, stronger,  and more compassionate than people give her credit for. Which is why she would get along with the following five Marvel heroes but not stand five others.

10 Would Not: Star-Lord

Peter Quill takes aim with his laser gun in Marvel Comics

While there are many ways to describe Peter Quill, most of them being derogatory,  the most fitting would have to be ambitious. Naturally, the leader of the Guardians of the Galaxy would be a risk-taker in order to unite his band of misfits. Such a quality is his biggest strength as well as his biggest weakness. Another weakness of his is women. It's no secret that Star-Lord is a bit of a womanizer and he would make a move on Starfire.

He doesn't stand a chance given that a lot of his pick-up lines would go over her head. Even then she would discover his intentions and want nothing to do with him. Though if she had to pick her favorite out of the team...

9 Would: Groot

It's not easy being green. Or made of wood. Or only being able to say "I am Groot". Most of the time his team understands what he's saying but everyone in the galaxy doesn't understand a word he's saying. It's a good thing that Starfire can learn entire languages through kissing. Just one friendly peck on the lips and the two of them will be able to talk for hours, even if they're only saying "I am Groot".

Considering that they both possess super-strength, get judged by their appearances, and act as the heart of their respective teams it shouldn't be hard for them to find something to discuss. If she's not careful Rocket might end get jealous.

8 Would Not: Punisher

Frank Castle is a tragic man with a justifiably tragic past. Starfire would understand how the murder of his family would warp him into the mass-murdering vigilante he is today. While she would agree that organized crime is an issue that needs to be stopped, she wouldn't agree with his methods or mentality.

She would certainly try her best to convince Frank that he should move on but it is unlikely she would succeed. If anything he would find her extremely naive and annoyed by her upbeat attitude. Try as she might, even Starfire would realize that she can't change the Punisher and that they couldn't work together.

7 Would: Spider-Man

Spider-Man, on the other hand, would be the ideal hero for Starfire to team up within New York City. For one thing, Peter would be more than happy to take her sightseeing around the Big Apple. They'd probably stop the occasional purse snatcher or robbery and then go get grab a slice of, what Peter assures her is, the best deep dish pizza in town.

On top of that, Starfire would find his quips confusing yet amusing and admire how he honors his Uncle Ben. By the next day, J. Jonah Jameson will be ranting about them being a new power couple, criticizing her outfit, and giving the two something new that they have in common.

6 Would Not: Deadpool

Comedy is subjective. Deadpool will have to learn that the hard way if he ever crosses path with Starfire. His pop culture references and meta-comedy are going to wind up lost on the Tamaranean, but that's fine. If she can deal with Beast Boy's jokes she should be able to tolerate Deadpool. It's only when he breaks out the firearms that she will have a problem.

If Starfire were to ever witness Deadpool in the heat of battle slicing his foes to pieces and cracking one-liners, she would be appalled by his gruesome techniques and disregard for life. Unless he's in a story aimed at younger audiences but even then he'd find a way to push the boundaries. It also doesn't help that he'd remind her of Deathstroke.

5 Would: Captain America

While these two come from completely different worlds and time periods, Starfire and Steve Rogers are all too familiar with oppression. The two have seen the best and worst the universe has to offer but they didn't falter. They persevered and fought the good fight to help those who couldn't fight for themselves.

They both refuse to sacrifice their teammates and would give their lives for their principles and friends. They wouldn't just get along, they would have each other's respect. They'd also be confused by modern slang.

4 Would Not: Ghost Rider

They say not to judge a book by its cover, but in Ghost Rider's case, his book is the Necronomicon. If Johnny Blaze didn't have control over the demon possessing him or his powers, Starfire would understand why he goes overboard with his abilities. Once she learns that he is in control and actively going all out to make his enemies suffer, that is a different story.

Although his victims are typically those who warrant harsh punishments Starfire wouldn't allow such sentences to be passed. Ultimately she will just let him ride off and go find someone nicer to spend her time with.

3 Would: Colossus

As the leader of the Teen Titans following Robin's departure, Starfire would naturally be interested in visiting a school dedicated to teaching students with powers. While she is bound to make friends with most of the teachers, even Wolverine, she would likely get along the most with Colossus. Despite his hard, intimidating, metallic exterior, Starfire is sure to look past that and see him for the gentle giant that he is.

As shown in Deadpool and Deadpool 2, Colossus is an absolute gentleman, team player, and overall nice guy. Not only would they work well in the heat of battle if the mansion gets attacked but the two could compare notes on teaching and dealing with rowdy teammates.

2 Would Not: Namor

Namor has always been a problematic hero in the Marvel Universe. To put it lightly, he doesn't get along well with others. Especially since he thinks poorly of surface dwellers, with a few exceptions. Granted being on dry land for long periods of time can mess with his mind and humans don't exactly have the best track record with mother nature.

Yet considering Starfire and her race have been the subjects of bigotry, she wouldn't take kindly to Namor's close-minded attitude. Until he learns to be more friendly, Starfire won't be making any vacation plans under the sea.

1 Would: Thor

Let's go down the checklist of similarities between Thor and Starfire. Do both come from a far-off planet of peaceful warriors? Check! Both know how to handle themselves in a brawl and are among the strongest members of their respective teams? Check! Both have a sibling they care about that continually attempts to kill them? Check!

Both of them consider the Earth as their home but still have trouble grasping modern concepts? Check! All they need is a flagon of ale and then they can spend the night swapping tales of their adventures.
