Summary
Important Note: This is a fan continuation of "Tiger of the Pride" by orphan_account, posted with the permission of AO3. If you would like the full story, please read the fanfic that inspired me first :).
Tygra has finally achieved his lifelong dream... he has met other tigers and traveled to the home of his birth clan. But his family isn't quite what Tygra expected, and not every cat sees the prince's return as a good thing. New enemies take an interest in Tygra, while friends and family alike try to twist the situation to their advantage.
Tygra struggles to deal with the pressure and his conflicting loyalties while training to be a 'proper' tiger. Meanwhile, Lion-O wrestles with his father Claudus' increasing demands, with no Tygra there to share the duty. As Lion-O strives to hold onto his beliefs, he begins to realize... maybe he didn't hate his brother after all.

Summary
An ancient empire stood proud and resplendent before many on Third Earth, but an ancient being that tormented this world resurfaced, causing the empire to fall. But this also awakened a new victor, bringing a union born from the heart, his ideal, but also someone capable of experiencing and feeling as many other beings of Third Earth have felt in a very particular way.
AU - What would have happened if the two lizards that Lion-O defended, instead of subtly giving him the key to open the cell that held him and Tygra, had intervened at another time in a desperate attempt to save Lion-O by enslaving him?

These were days of peace and prosperity on third earth, when one empire stood above all others, ruling with a just heart and razor claws. And though Omens foretold in the book would be ignored, the tragedy to come was necessary.

Summary
(Rated Mature for the Catra POV Narration more than anything.)
Basically, Hordak is Galra, a former Imperial scientist, and Shadow Weaver is Altean, they were part of a joint mission to find new planets together right before the war broke out between their two peoples. Mara was on the mission and was also Altean, and She-Ra had always been before that.
When they got news of the war breaking out, the crew of the research mission took sides. Hordak got most of them under his banner in Scorpia's Kingdom/The Fright Zone, along with some of the native people there, as the first generation of the Horde.
Mara tried to stop him, but couldn't, so she moved Etheria into a pocket dimension that no communications could get in or out of, to protect the Heart of Etheria from falling into Zarkon's hands.
Shadow Weaver tried to scheme her way into ruling Mystacor, and joined Hordak when that failed.
Ten thousand years passed.
Now, Light Hope has just moved Etheria back through the portal at the end of Season 4.
Instead of Horde Prime coming to Etheria and capturing Catra, Glimmer and Hordak, it's Zarkon. Events follow from there. -

Summary
The history of the cats on Third Earth has always been complicated. Especially the connection between the Tiger and Lion clans. History repeats with tragedy but perhaps the chosen king's tale will not be the case. Lion-O and Tygra grow together but feel the confusing pull to one another and on their journey in seeing this relationship through they experience many obstacles. Along with this Lion-O’s burden becomes reality upon the return of Mumm-Ra and needing to defeat the old enemy to return the peace. The young king while developing a bond with the tiger also is joined with multiple allies and changes along the way. Though both Tygra and Lion-O will also have to face the past of their ancestors while overcoming the coming storm. Hopefully, the young king will see they are not alone…
