Help me plan my Fan-Fiction!

[KopsTheTerminator]

I've had this idea in my head for a while now, and I'd really like to turn it into a Fan-Fiction. It's an alternate version of Simba's Pride: Kopa was the only cub of Simba, but someone is out to get both father and son.. This will be more of a story of friendship and royalty, rather than a love story (well, if the fourth storyline is picked, then they'll be a little romance in it).

Now, I have three alternate storylines, and I just can't decide which one to use. What do you guys think? Which storyline should I use?

• Storyline #1: The Outsiders don't exist. Afua's father is the one and only Scar, and Afua's mother, Umiza, is plotting revenge. Her son's friendship with the young prince benefits her, but will her son be capable of killing his best friend?
  
• Storyline #2: Afua is exiled with the rest of the Outsiders. Zira wants to have Afua help Kovu with his quest to kill Kopa and Simba, because he's Kopa's best friend, but his mother does not approve, so she's killed and Afua is adopted by Zira. Afua is trained with Kovu and he's secretly meeting Kopa with Kovu because they're still best friends. Kopa doesn't fully trust Kovu and he knows something's wrong about him, but he decides to trust his best friend. But his decision might end up in the downfall of the Pride Lands...
  
• Storyline #3: Afua is the only son of Zira and he's Scar's son. He has a hatred for Kopa and Simba for killing his father. He's pretending to be his best friend, but he and his mother are plotting to kill him. But how long will the hatred last? Will the hatred last for that long, or will the power of friendship chase the hatred away?
  
• Storyline #4: Tojo and Tama have two cubs called Afua and Vitani. Kopa and Vitani fall in love as adolescents, but Tojo and Tama don't approve, because they're exiled from the Pride Lands because Simba thought they posed a threat to the kingdom, although they were cubhood friends. Afua is Kopa's best friend, but he's willing to listen to his parents and get rid of that brat Kopa once for all...

''And how the world will Afua look in your storyline anyway?''

Oh, he will look something like this!

Voted for number one. Reason being, it's the option most unlike the storyline of SP itself for me. If those trying to hurt Simba and his family are ALREADY on the inside and don't have this sort-of back-and-forth communication with the borderlands, it could make for more interesting and novel storylines. 3 sounds way too much like the original to me, and 2 less so. A runner-up for me would be number 4. 1 is my vote, though.

Thanks for your votes. I agree, #1 and #4 are the most original ones.
