My theory is that Kopa after long years in desert finally return to Prideland, but he doesn't wanted to be king. Instead of that Vitani  left with him to the desert, where they had their own pride of desert lions. Then Vitani and Kopa had two cubs, Theo and Zia.

I love the theory where Kion brings Kopa home. I bet that one of the things that would get Kopa to return to his family at Pride Rock is if Kion knew how much Kopa and Vitani really love each other, and he would tell Kopa that Vitani is worried about him and misses him. That would really help Kopa to return to return to the Pride Lands and reunite with his father Simba, his mother Nala, his sister Kiara, and in time, Vitani as well. And after all, Kopa getting to survive Zira's attack him just proves that Kopa is not the one to not get the last laugh.

My issue with the theories is that Kion doesn't have the mark of the guard anymore, he gave it to Vitani.

the 2nd theory seems more neutral
though there are ideas of the 1st theory that could work in the second
my theory Based on mixing both 1 and 2 is:
kopa does come to the pridelands with the aid of kion,
and rather than kion leaving , as the first theory suggests
my version of the second theory basically is that, kion would take kopa in, and simba and nala would agree with this idea
and both of them, given that they are brothers, would each be allowed to take in lionesses of their own choice to expand the pride

The story of little Kopa is very sad. After surviving Zira’s attack, not even his father talked or remembered him anymore. In my opinion, he didn’t come back to pridelands.

My personal theory is that Kion, now king of the tree of life, welcomed Kopa into the kingdom when he came for healing. And then led him home to the pride lands where he saw his family again. And, Kopa had a family with Vitani and helped her lead the guard as the smartest on the Lion Guard.





Smartest added by Ono becoming the smartest on the Lion Guard in season 3.

I’ve always wished Kion met Kopa!!!!

Gosh i wish they made a lion king 3 explaining everything that happened to Kopa

I choosed the 2nd theory,
Because my own theory is that after he returned to the Pride lands,he didn't just met Kion,but he met Vitani and he falls in love with her and they lived happily each other.
             THE END!
  "THANK YOU FOR READING!"

My opinion: Kopa returns to Pride Rock, gets married to Vitani, and becomes co-leader of the Lion Guard.

My theory is he was attacked by zira and thought to be dead.... he grew and thought everyone had forgotten about him he returns one day and he meets kion but runs off to make a pride with vitani

Theory 2 should be a episode in the lion guard

My theory is kind of a mix. I think Kopa lived and lived by the deserts where kion walked through. Kovu and Kiara never saw him because you have to travel out a little bit. Kopa sees kion and thinks he is attacking an innocent animal and he fights kion and they soon figure out what was really going on. I think Kopa never new what the lion guard was. He wasn't around when scar had it and kiara didn't even know it so why would he? And who that's not all but imma stop now. 😂❤️

Kopa is alive but still hurting and he hears about the tree of life and meets his brother and sister-in-law. Kopa is healed from his years of pain. He stays at the tree of life for a while. He soons asks Kion about his parents and Vitani. While at the tree of life, he meets the night pride healer Nirmala. He  takes a liking to her. She gives him tasks to accomplish. Once he's ready. He
farewell to the Lion Guard and the Night Pride and heads to the pridelands. The king and queen our elated  and cried tears of joy when they see that their son, who they thought was dead, is now alive.  He reunites with Vitani who found love with another lion. Kopa is sad. He stays at the pridelands where Simba and Nala tries to cheer him up.  Later, Kopa travels to the southern part of the Continent and meet a queen lioness. He falls in love with her and becomes king.

1 was my favorite. Theory Kopa’s lives and has a family

Knowing his own experiences on his own and how protective simba is of kiara and kion there is no way simba wouldn’t go searching for kopa

And If he ran away when he was young he wouldn’t have been old enough to learn about the guard so how could he have recognized it

I say for Kion instead of meeting Rani. he could of reunited with Kopa his brother. Kopa could of been taken in by Queen Janna and Kion comes and he recognizes Kopa from Rafikis paintings but doesn’t know where he saw it

3:50 that picture is from slothastic

Er, you forgot something crucial about Kion: He's the king of the Night Pride and mate to Rani now! None of these theories could remotely work if Kion goes back.

My opinion after Kion becomes Rani’s partner and he is king of the tree of life Kopa goes to the tree seeking help and they meet. After Kopa hears the roar of the elders he realizes that Kion is from the pride lands. Where Kopa gets Kion to agree to go back to the pridelands and explains everything there. (Kiara is also queen by then)
