Watermark is a founding member of GUARD team Alpha. Watermark is a alien shapeshifter that crash landed on Earth. The being has no memory of life before the crash, but he was running from a powerful force. Landing in California, he turned into a blue skinned surfer he had seen near the beach. At first he terrorized the locals, but was found by the government and sent to GUARD for further evaluation. While at GUARD he honed his skills and can shapeshift to any creature he has seen and learned about. Though he still suffers from amnesia, he has proven his worth many times over.
