Another attempt for a crossover...haha I'm not that sure what to say here...I just hope it's okay. It's only a Prologue so...please enjoy! And review too...

"Hurry up Oddish! You're falling behind!" a young voice came from the bushes. The voice came from a child who was wearing a simple green shirt with a thick white line in the middle. His navy blue shorts were a little dirty from crawling around the bushes a lot. You could be asking what an eight year old would be doing in such a place with one grass/poison type pokémon following him, well here's the gist of it.

This is little Harada Riku and his...bodyguard, Oddish. There wasn't much to do in the house for Riku, and ever since Senri disappeared, it has been way more boring than he ever experienced before. So, convincing his grandparents to let him go outside, they agreed on one condition...

And that was this little pokémon.

"Oddish-odd! Oddish!" the weed pokémon cried to him. It was really hard keeping up with him; well the fact that an Oddish doesn't have hands hinders him a bit, with all the twigs and leaves brushing on him.

Finally, the pokémon was able to catch a small tinge of light. He ran towards it and was greeted with the warm sunlight on his blue body, the leaves on its head seemed restored and healthy.

"There you are! What took you so long Oddish?" the child asked while bending down to his grandpa's trusty pokémon.

"Oddish-Oddish-Odd!"

"It's not my fault! I just didn't want it to be boring!"

"Oddish-Odd..?"

"It won't be exciting if we've taken the usual path Oddish." the grass pokémon decided not to argue with him anymore, anyway they were here, so why bother?

The two were standing in front of Lake Verity, a place where Riku tends to go whenever there was nothing to do. There is actually a walking path to get here, but as you can see, Riku thought otherwise.

The lake was as clear as always. The boy loved it here since it's always so peaceful, and because of the stories his brother would tell him often, about a legendary pokémon living deep within the lake. The trainer would occasionally tell his little brother that it wasn't a myth, for the reason that he has seen the pokémon himself before he became a pokémon trainer. No one would believe him except for Riku, who was always asking him to describe how the pokémon looked like and his experience with it. The story made the boy want to meet the legendary as well because according to Senri, Mesprit was friendly. Yet now...

"Oddish? You think Mesprit would know what happened to Big Brother?" he murmured. They were sitting on the grass as they both gazed at Lake Verity. The grass pokémon looked at him and gave Riku a puzzled face. "Oddish..."

"Yeah, maybe...but we might never know huh?" Oddish pitied the child. He's been trying to make such a strong face for everyone when Senri was gone. In truth, he was the one everyone expected to grieve the most, but he was actually the quickest to recover. And in a short span of time he was smiling again, which helped everyone feel better. Oddish felt the bottled emotions inside him...they were so strong that it was surrounding him like a veil...

"So what do you want to do now Oddish?" Riku suddenly asked, and the veil swiftly disappeared. The pokémon glanced at the kid's face. Smiling...he wondered how he was able to take for so long, even though it was barely a year since his big brother...you know the rest.

"Oddish...Odd..?" he ran to a nearby tree filled with Sitrus berries. The little pokémon tried to climb it, but his body wasn't made to do such, so he kept on falling on the grass.

"Oddish, you know that you have to evolve first before you can climb..."

"Oddish-Odd-Oddish!" he retorted back.

"Well I'm not saying it's impossible but..." the pokémon didn't pay attention him because he was focused on climbing the tree. Riku sighed; it was always like him to do that. The kid turned back to the lake, just gazing at it made him feel better...

"...huh?" Riku noticed that a small part of the lake was...glowing. He ran closer to the lake and tried to take a better look when all of a sudden, he felt like he was pulled into the lake. "H-help! Oddish!" the pokémon wasn't even aware of Riku's cry, because it was already silenced by the water engulfing the boy...

"Odd?" at some point, the little pokémon finally gave up trying to climb the tree. He turned around and expected to see the child there--

"Oddish?!" the pokémon was shocked that there was no one in sight. The pokémon quickly scanned his surroundings, but there was no sign of him. 'Oh what am I going to tell him? That Riku just disappeared?...' he shuddered at the thought, half because of the humongous punishment he was going to get, and the other because...it feels too similar like the time they all lost Senri...
