DIN-01 lolled her head to one side in confusion in response to Winter's challenge. Without any words to compliment her body language it wasn't clear what exactly it was about what he'd said to elicit that reaction but, sure enough, she plucked a pokeball from her waist and primed it in preparation to engage Winter. She seemed to consider the pokemon he had sent out for a moment, quietly rolling the enlarged ball out of her palm and onto the ground. From it, a pikachu emerged. The heart shaped curvature at the end of her tail identified her as being female, but otherwise, there wasn't much to observe about the pokemon! That is to say, there was nothing strange about it, at least. The mouse pokemon shuddered in the cold, but quickly shook off her discomfort by shifting onto all fours into a battle-ready position and beginning to bounce rather energetically.
...And then, DIN-01's move came. It came without a command, or any real warning really. DIN-01's pikachu abruptly shot across the snow, using its light weight and decisive speed to cross the icy battlefield without ever really succumbing to any difficulty moving about. And then--she stopped. DIN-01's pikachu was baiting out a defensive action on Winter's part, and by all accounts one was warranted. Yet, Pikachu's attack never came. The pokemon abruptly made a U-turn just before committing to slamming into Winter's squirtle and quickly darted around the pokmon's side away from it. This was known as Fake Out. Pikachu then began running circles around the battlefield, picking up an enormous amount of speed as she literally began running circles around Lucky. An experienced trainer might recognize this as the move agility. As Pikachu did this, her increasingly egregious speed began to kick up snow behind her, creating a little wall of thick icy mist around Lucky that hampered his visibility, allowing her to duck in and out of the wall very so often as she ran to keep either Lucky or Winter from pinning down where exactly she was.
The wind picks up, carrying a mournful wail with it as it settles over the battlfield.
