Catra voiced by Melendy Britt
First seen in the episode “Into Etheria”
Catra is the Horde’s main Force Captain, leading other Hordesmen into battle with the Rebellion.
Catra is one of the few members of the Horde who has anything akin to a backstory.
When the feline Magicat people were taken captive, their Queen went on a search to find them.
However, Queen of the Magicats was captured too and imprisoned by Hordak.
Powerless without the enchanted mask which gave her magical powers, she could not escape.
Hordak had given the mask to Catra, from which the villainess supposedly obtained her cat-like qualities and certainly her ability to transform into a ruthless panther. 
Though the Magicats were to see their Queen again, Catra retained the mask and, therefore, her power of transformation.
Unbeknownst to Catra, though, the mask also has another ability – simply by saying ‘freeze-fire’, the mask can fire a freeze-ray which will cover anything in its path in solid ice.
She did learn this trick but no longer remembers it due to the mind-wiping power of the Magicats. 
To transform into her panther form, Catra would simply place the mask on her forehead over her eyes.
A strange gas would be released from her body, as she changes. [First in 01]
In this feline form, Catra would retain the ability to speak but would be gifted with the strength of a panther in addition.
Following Adora’s departure from the Horde, Catra was made Force Captain in her place, [referenced in 06, first in 07], commanding Mantenna, Leech, Grizzlor, Scorpia,  and occasionally Rattlor to do her bidding. 
This position would be a frequent reminder of Catra’s authority throughout the series; she would only once be given the different title of Force Commander. 
Despite their differences, the Horde members share one mutual opinion – utter contempt for Imp.
The sultry Catra showed a clear attraction to Sea Hawk. 
Her flirting was not reciprocated though, which perhaps gave her extra reason beyond his treachery to arrest him – and even set a trap for him and Adora. 
Finally, perhaps the most unknown fact about Catra is her ability to teleport  – perhaps another power granted by her mysterious mask?
We may never know.
Clawdeen is Catra’s pet.
Clawdeen’s one appearance in the She-Ra series revealed little about her.
We know she is Catra’s pet and that she is based out of (what appears to be) Catra’s Tree-Plex from an early Princess of Power Mini-comic, but little else.
She was used in the second season to scare the Rebels into Cage-Mines so they could be captured by the Horde, who in the end, got away with Peekablue.
She vanished after Bow trapped her in a Cage Mine, though Clawdeen and Catra in her cat-form did seem to make a powerful team when working together.
