WildStorm: Set 1 (Base Set) 28-A

"To say that Karl Hansen's power is that of the sun is not to far understate the case. Sunburst's body acts much like a fusion reactor, generating its own energy with which he fires powerful solar blasts and flies. As his temper heats up, so does his ability, although he keeps a lid on it around his wife Nautika, a fellow member of StormWatch Prime." *Source: Card Back
