WARNING: The following article contains spoilers for the fourth season of She-Ra and the Princesses of Power, now streaming on Netflix.

Season 4 of Netflix's She-Ra and the Princesses of Power pushed the Princess Rebellion to its limit following Catra and Hordak's decision to ramp up attacks all over Etheria. Angered by the portal Entrapta opened at the end of last season which allowed Horde Prime to sense the planet, the villainous duo go all out so they could enslave Etheria by the time the cosmic tyrant arrives to impress him.

However, as cruel as both are, it's actually the non-binary mercenary known as Double Trouble (Jacob Tobia) who proves to be the franchise's most sinister yet.

Double Trouble sneaks their way into Catra's platoon early on after she asserts a degree of dominance over Hordak. Catra no longer wants to play second fiddle and Hordak surprisingly gives her more agency, recognizing he needs help to aid his takeover before his older brother arrives. And so, with the arrival of the shape-shifting Double Trouble, Catra gets her biggest weapon to date as she spots the potential in just how realistic their abilities are when it comes to impersonating people.

They disguise as Catra and dupe Hordak, which confirms how talented they are, being a thespian who loves stage performances and whatnot. Catra puts Double Trouble's flair to good use later on and with the mercenary actually showing up her boss by infiltrating the Rebellion as a runaway picked up called Flutterina.

Planted by Catra, Double Trouble goes about infiltrating all corners of Bright Moon as Flutterina, sowing discord everywhere to the point a civil war breaks out between Adora and Queen Glimmer. Double Trouble convinces Glimmer Adora doesn't respect her and then tricks Adora into thinking Glimmer is mad with power and lusting for control of all Etheria's kingdoms. Double Trouble comes off conniving like Daniel Brühl's Baron Zemo in Captain America: Civil War, fracturing the friendship, gaslighting everyone with ease, all while popping in and out the Fright Zone to celebrate with Catra.

With these seeds planted, Glimmer -- even after discovering Double Trouble's ruse -- wants to prove she can deliver as Queen and goes after the Black Garnet, being tricked by Light Hope as part of the A.I.'s plan to turn Etheria into a Death Star. To put it simply, Double Trouble knocks off the thing Hordak and Catra tried to achieve in all the seasons before: destabilizing the Princess Rebellion to the point it almost destroys itself. And what makes it worse is they don't care whose side they're on, as long as they're paid handsomely.

This is why Double Trouble double-crosses Catra and Hordak towards the end, escaping Bright Moon after discerning Glimmer's move for the Garnet. They're playing both sides and after understanding Light Hope's actions will make whosoever aligns with her Etherian mission an elite in the galaxy, Double Trouble helps take out Hordak and Catra so Glimmer can achieve her goal and unwittingly bring Etheria out the realm of Despondos to become a planet destroyer. Double Trouble leaves with their mission complete, reminding Catra no one should be trusted, finally breaking her.

It's pretty slick to see them emerge triumphant over the Horde's leaders like this, hitting all their goals without anyone seeing them coming. As a gun for hire, Double Trouble legitimately leaves all the big players in Etheria -- both heroes and villains -- staring doom in the face as they run away knowing a new era's beginning. And so, while Etheria doesn't get turned into a weapon thanks to Adora's wiles, Horde Prime does arrive and kidnap Glimmer. He also abducts Hordak and Catra to commence his new plan of weaponizing the planet for himself. Of course, this was made easier because of Double Trouble, who weakened both sides and left the planet ripe for the taking, a boon Horde Prime's legion graciously accepts.

Streaming now on Netflix, She-Ra and the Princesses of Power stars Aimee Carrero, Karen Fukuhara, AJ Michalka, Marcus Scribner, Reshma Shetty, Lorraine Toussaint, Keston John, Lauren Ash, Christine Woods, Genesis Rodriguez, Jordan Fisher, Vella Lovell, Merit Leighton, Sandra Oh, Krystal Joy Brown and Jacob Tobia.
