Scar is a very interesting character that betrays mufasa by killing him. And he also would lead little simba and nala to the elephant grave yard where its very dangerous. Its where the hyeanas live and they prey on younger lion cubs which make them savages. Scar is the antagonist of lion king and is both mufasa brother and simbas uncle. This movie is such a great movie but, sad at the sametime. The pride lands was where the Lions but scar lived. It was so beautiful there and all the animals got along with each other. Scar didnt live there because he was the one who wanted to be the king not his brother. So he got jealous and end up killing him and became king allowing heyeanas into the pride lands causing havoc. Now that they have made a lion king to the saga can continue. Its amazing to watch this movie and will continue to watch it. When timone and pumba return to find simba they helped him grow into a fearless lion along with nala. They end up being together which is so cute. So they return back to the pride lands to fight off scar army of heyeanas with his army. The fight was brutal but simba and his alliance end up winning the war and took over the pride lands again. When simba and scar was alone they fought each other , simba end up winnig. Scar tried to blame mufasa death on the heyanas but simba didnt believe him. So he threw him over the cliff. The heyeanas heard everything scar was saying and all three of them killed scar to finish off the job. This was a wounderful ending to the movie. Nala and Simba end up making a baby cub. You will just have to find out what happens by just watching lion king 2 which was another great movie.
