Simba becomes King

After Simba is manipulated into believing he killed his father and going into self-imposes exile, allowing Scar to become King and ruin the Pride Lands, he eventually grows up and returns to reclaim his throne. The move ends on a well earned happy note, as he defeats Scar, becomes King, restores the Pride Lands to their former glory and even becomes a father himself.
