Riku has Gigabyte the... incredibly glitchy Porygon2. Very twitchy, unstable, and has never actually encountered other Porygons before. How does I socialize?

Surge the Rotom will be accompanying him, and of the two he's by far the more stable. Friendly, energetic, and insanely curious. Also a touch mischievous. This is what happens when you hang with a Haunter and Zoroark.
