Taking on one skilled fighter is hard enough, even more so when you have to take on two who are fighting not just for the safety of others, but for each other also.
It can sometimes be a distraction to have a loved one there whom you're always watching out for but these lot have total trust in each other's abilities to handle themselves in a fight; in whatever form it comes.
This gives them an added clarity of mind seldom seen in lone fighters. If that is a good or bad thing depends on which side of their fists you're on. Without further ado, let's count down our favorite couples you'd do well to steer clear of in a fight.
1. Lorna and Marcos (The Gifted)
With just a touch, these lovebirds can conjure up a miniature version of the most beautiful phenomenon you'll ever see -- the aurora borealis. What are the chances that out of all the mutants out there, they'd find and fall in love with each other? It's fate, you guys. But those same abilities that produce that amazing sight can be utilized to devastating effect. Just ask all the Sentinel agents that have stood in their way.
2. Sara Lance and Ava Sharpe (Legends Of Tomorrow)
What started off as a slightly antagonistic relationship quickly turned into the best love story this show has ever done. Sure, the bar isn't that high, but it doesn't take away from the euphoric feeling you experience when watching these two lay the hurt on the baddies.
3. Mon-El and Imra (Supergirl)
Sci-Fi shows constantly play it fast and loose with the mechanics of time travel, but one thing that has remained consistent is how often it gives birth to complicated relationships. After Mon-El left Earth to escape Lead poisoning, he fell into a wormhole into the future where he married Imra -- a fellow member of The Legion. They returned to the present where their fighting skills were put to good use taking down the Worldkillers.
4. Sameen Shaw and Root (Person Of Interest)
Shaw is an expert in a myriad of martial arts techniques and has taken down bad guys three times her size. Root, while not at the same level physically, can ruin your whole life with the press of a button.
5. Hermione and Hiram Lodge (Riverdale)
It's a shame watching Hiram descend to such petty levels, expending significant resources trying to kill a teenage boy. Yet, somehow Archie keeps getting away, which kind of dampens the effect of the knowledge of how deep Hiram's mob ties run. But before he got out of prison, Hermione was the Armani-clad puppet master gracefully pulling the strings from behind her Gucci curtains, or whichever brand is the top dog in the curtain-making game these days.
6. Tulip and Jesse (Preacher)
To call Tulip and Jesse's relationship complicated would be the understatement of the year but they always have each other's backs whatever comes their way. Long may it continue.
