Aliens

Doom
Tree / Tree of light
The Doom Tree is were they fed energy to keep it alive. If
the tree should every die Allan and Ann would also died two.
In the final battle between the trees was very angry with Ann
and Allan and fought against them. She lifted one of her root and aimed
it at Allan. But Ann jumped in front of it and was speared through the
heart. Allan was surprise at what she did and begged her not to die. All
she said to Allan was not to for get her. And she died. The Doom
Tree was about to kill Allan also but Sailor Moon stopped it. The tree
stopped and began to tell its story by taking Allan and the Scouts into her
mind.
A long time ago the tree live in the middle of the ocean in a
planet far away. The tree would give life to many aliens. They
lived in a time of love and harmony. Soon Ann and Allan were born.
Then all the aliens began to start fighting over the energy of the tree.
Destroying each other for power. The tree manages to escape with Allan,
Ann and others that were save. The other began to die except Allan and
Ann. Growing up in a world of hate all they knew was to fight. So
when they were trying to get energy with pure evil it was poisoning the
tree. All the tree need was loved to survive. So the tree asked
Sailor Moon to purify it from the evil energy it received. So Sailor Moon
agreed and she used her "Moon Scepter Elimination" to transform the
tree to a seed. Ann came back to life and that made Allan very
happy. Allan and Ann got the seed and left to start over in a world of
love.

Allan & Ann
Allan and Ann were aliens that were traveling though the universe trying to find energy to feed their Doom Tree. They created monsters to get them their energy. Once the monster got the energy they need could they would feed it to the Doom Tree and the tree would give the energy to Allan and Ann. And if the tree didn't get the energy it would die and if died Allan and Ann would die also.
