"...It's time to take care of Uncle Scar once and for
all. And you'll meet him for the first time at the start of this stage.
You'll meet him once more before the fight to the finish. When fighting
him, don't, and I mean don't use the X slash, or he'll use his fatal slap
attack where he jumps on Simba and claws him to death. Use your swipe
and the downswipe. You can also use the ducking slash safely. Throw him when
you can. When you've worn him out, he'll smirk and run off. Go left, jump
from rock to rock, fight the hyena, go up, fight, watching out for
lightning strikes that will ignite the ground. Proceed to the right taking
care not to fall, otherwise you'll fall to the beginning of the stage
and have to go from when you scared Scar off. Jumping from rock to rock
cling to the right wall, work your way to the top (reminded me of Ninja
Gaiden II). Then jump to the left. Fight the hyenas and proceed to
the left. Preserve your life because there are no midway points in
this stage (you know what that means). Jump on the rocks and swing up
and around onto the ledge. You'll meet Scar again here. Same deal. After
you scare him off proceed right. You must now climb to the top of Pride
Rock. There are frequent lightning strikes now. If you have enough health,
go through the fire, if not go around. Keep working your way up until
you can't go up and higher. Go to the left and you'll find Scar. The final
battle will ensue."
