Which Arrowverse Character Would Be The Perfect Doctor Who Companion?

Diego, I'll bite! Let's dive into the traits of a proper Doctor Who companion. They need to be brave and adventurous, traits that are an absolute must for any journey through the universe. Chasing the Doctor across the cosmos isn't for the faint of heart!

Moreover, a companion likely shouldn't be too deeply tied to anything Earthly. Family left behind should be fine with a few visits home, at least until Clara, who from the start insisted on a proper life outside of the Doctor's universe. But even Clara almost overwhelmed by her commitment sometimes!

Intelligence is essential, but a quick wit reigns supreme. The Doctor prefers to work with someone who can think on their feet. After all, who would bother with a companion who can't handle crises?

Leadership and Trust

These companions must be capable of taking charge when necessary and knowing when to recede into the shadows. They must be trustworthy, as well as willing to lead. The decision on which role to play isn't something they can dwindle on in the heat of the moment.

Most importantly, the companions cannot be intimidated by the Doctor. He needs a person who can tell him 'no' if need be. The Doctor needs someone he can trust to hold his leash and stop him when necessary.

The Doctor values being admired and seen as a hero by his companion. It's a look in their eyes that makes him believe in his heroic role. The companion must be able to see the good in him, as this is a crucial part of what drives him to be a better person.

A Requisite for Survival

Experience with trauma helps, and companions must be comfortable with the darker side of the Doctor. Donna nearly lost her chance to travel with him because she was so scared. They must be capable of pulling him back and believe that they can always guide him back to the good path.

Now, let's look at which Arrowverse character could fill these roles.

Exploring Kara Danvers

Of course, I know you'll favor Kara. She's an excellent candidate for a Doctor Who companion. Her hopeful and optimistic nature, combined with her sense of adventure and fun, make her a perfect fit. Kara is powerful and durable enough to be super useful without being a constant liability like previous companions.

Given Superman and the DEO around, it's likely that Earth could spare her. Kara has extensive experience travel through time and dealing with trauma, making her a seasoned time traveler. She has an adventurous streak and is a natural leader. She can step back and follow when she trusts the leader, and she has a good heart, capable of calling out goodness in others.

Other Suitables

I considered other names but found it challenging. Iris West, for instance, almost fulfills the companion role for Barry, but her unbreakable attachment to her world and family makes the transition impossible. Caitlin can almost fulfill all the requirements - she doesn't have much to keep her on Earth - but it's hard to see her stepping up to take the Doctor's place.

Given her background, Kara stands out as the ideal candidate. She's already traveled through time, has experienced trauma, and is durable enough to be a valuable companion. Given enough time to develop a strong platonic bond with the Doctor, she could become an excellent companion.

Provided someone else could take over as the Waverider captain, the TARDIS wouldn't mind having a little white canary on board. Kara and the Doctor could develop a deep and meaningful platonic bond.
