She was still young, a reincarnated Suicune. Most definitely the youngest out of the three siblings. Raiku was the middle who had recently gained his full powers but has remained out of sight for a while. Entei is the oldest. He still had much time before he was too old to continue. Suicune still had to learn much about her life, what her purpose was and the world around her. Humans were a lightly touched subject to her. So many would worship her as if she was a god and then there were those who would capture her for their cruel intentions at first sight.
Suicune didn't stay much from the Johto region, since it was the one she first appeared in. She knew she was supposed to clean all of the bodies of water to make them pure again but much else was unknown to her. There was just this fear of having someone waiting for her as soon as she left to use her for any wrongdoings. She had barely made acquaintances with Pokémon because of her lack of trust.
The next body of water she crossed upon was the Lake of Rage. She walked to the bank and looked down at the warer, her eyes adjusting to see the creatures under the surface. Slowly she took a step onto the water, like she was unsure she could stand on it. Instantly a small ring appeared getting only so big of a clearer, blue water. She took another step, them another. Soon she began to dance around, her eyes only focusing on her powers cleansing the lake. About a quarter of the lake became clean until she heard a voice that broke the still surface of the water.
Suicune stopped and stared at the untouched area before her. She heard the noise again before something shot out of the water. Her eyes only saw the red scales before dragon flames came at her. She jumped out of the way, but the flames still caught her hind leg.
This creature was huge and it's eyes were filled with an anger that would not cease. The pokemon became even more enraged when it saw Suicune standing before it like it was a challenge. It began to move wildly and unpredictably, making it hard for Suicune to have a solid surface to stand on. When it saw her defenseless it rammed it's body into her, sending her flying into one of the higher banks nearby.
A cry echoed as she slammed into the bank. When she opened her eyes she saw flames coming once again. She scrambled but missed the attack completely. Though she was in such a panic she did not pay attention to where she was going. She scraped her self against several trees as she barely missed them as she ran. The moment she looked back was when she made it worse for herself. She tripped over a dead tree laying on the ground and fell, only to begin rolling down a hill only to have a large oak tree stop her.
Pain jabbed at every angle without hesitation. She broke her silence with a small cry, knowing no one would ever be out in this thick of a forest to at least acknowledge her existence. Her eyes closed, accepting her fate. She was not meant to be a legendary pokemon. She showered the name with disgrace. Protecting herself was no easy task and finally she failed for the last time.
