Compare the power blocks; this looks like it's been heavily reskinned. The power labeled as "Freezing Current" is actually freezing burst, from Heroes of the Fallen Lands. You're on your own for the rest.
I'm actually really impressed with the reskinning job. It's a bit too frostcheese-enabled, but it looks like a very fun, thematic character. I see Color Spray and Shield, with new flavor.
