This is my version of poor nuka's story:

One day during scars reign sarabi had another cub but he was one of scar's cubs, scar loved nuka very much but what scar didn't know is how weak nuka was until he was a month old and stuck very close to sarabi and the other lionesses and lazyed around with them all dayand was showing signs of being weakso scar started to hate him and told him that he would never be his heir and that made nuka cry to sarabi and she went really mad at scar for being mean to their son.

when zira came and jioned the pride scar loved her more then sarabi because she was more beautil then sarabi through his eyes. one day little nuka was asleep in the den while sarabi and the other lionesses where out hunting scar had told zira of nuka and hit nuka to wake him up and started to call him names sarabi and her lionesses came back from hunting and saw how mean scar was and went up behinde them and scared scar and zira and told them to leave her son alone and never to touch him and pick on him ever again

Zira felt sad for nuka and asked scar did nuka's mother die and scar said yes then zira adopted him and when he keeps getting older he would always be hit and called names by scar and his new mother zira and now zira hates nuka on the out side but still feals sorry for him .

months passed and simba came back to take back what was wright fully his and he one  and when sarabi got hit in the face by scar nuka yelled Noooo but when he saw simba he got jelous because he found out that simba was his half brother and would become king and not him.

the day zira got exiled she Stole nuka away from sarabi and the pride. Later everyone thought sarabi ran away and died her second son had been stollen away from her.a long time later nuka had forgotten his real mother and thinks zira was his mother and she hit him every day for no reason he cryed every day until he couldn't fell pain and he would always be sworn at by zira and vitani and kovu.

  Nuka hated kovu and vitani because they where spying on him and his girlfriends spotty,dotty and digger,he could always here them laugh and when he went to tell zira what they where doing she hit him and said they are angels and would do nothing of the sort and nuka ran off he was very annoyed he saw simba and tried to talk to him but simba wouldn't listen to him and rawred at nuka it hurt his feelings and nuka ran to his seceret hiding place that olny he knows where it is .

as soon as nuka went in his seceret hiding place he herd a very wise voice he looked around and couldnt see anyone but when he went to get a drink from the water whole in his hiding place he saw sarabi and they had a conversation and when he looked behind him sarabi was there she gave him a hug and told him she would always love him no matter what happens to him he thought that was odd and he told sarabi his mother would kill her.

Nuka had wished he was living in the pride lands where he would be treated nicely and that night he had a dream of the day he was born and he saw his real parents faces and when he was a month old in his dream and he wondered why zira didn't come in for most of it and he wondered whom his real mother was and he told zira and she told him that sarabi was his real mother and scar hated him for being very weak every thing, nuka was in shock but he loved everyone the same way.

but Zira always hated talking about sarabi because of her eldest son simba killed scar her husband and nuka's real father.she told nuka about how she would get revenge on simba and told him her plans and when then plains where in action she sent her other lionesses with Nuka to chase simba into the river bed, it blocked by a wall of sticks with water behind it.

when kovu tried to save simba nuka tried to kill simba by him self and chased after him and got him self killed and he hoped he would be in a nicer place for once and he was and he didn't get picked on and  would not be called names again he was happy to be in a better place then earth he girl friend's spotty and dotty where sad that nuka died because they where going to have his cubs.

when nuka got to heavenhe was made at scar and hit him and did the same things to scar ,that scar did to him and he told scar all he wanted was to be loved by his father the next day sarabi and zira jioned nuka and scar and mufasa and kopa in heaven and nuka was happy that he was in heaven with his mother and father
