Plot
NOTE: THIS IS UNFINISHED, AND CURRENTLY ONLY HAS THE MAIN POINT OF THE GAME, WITH PART OF THE BEGINNING.
Beginning: As you begin your adventure, you have the choice between Chibaby, Gualamme, and Sleether. After you get your first Pokemon, you battle your two rivals, Bruce and Katie. Bruce chooses the one yours is effective against, while Katie chooses the one your Pokemon is weak to. After the battles, Professor Maple heals you. Then, there's a scream, and you find a strange person fighting with a Mechanical Pokemon, and you must defeat him.
Main Points: Collect all 8 gym badges, and challenge the Titanium Cup. Along the way, you will meet Team Biomech, and learn they use Mechanical Pokemon to humiliate trainers who use living Pokemon. Right before the Titanium Cup, they confront you, using their Mechanical Legendary, and you must fight them using the Bio Legendary.
