Earth's ocean: an immense and drastically variable desert made of water, which hides a menagerie of the largest, the smallest, and the strangest creatures on the planet. Sunk in its dark and trackless depths lie ancient and forgotten relics, mingled with the spoils and remains of Man. This ocean, this vast mystery, is Seaspray's element, and he loves it dearly.
The oceans of Earth are not alone in his affections. On any planet, at any time, Seaspray is a consummate sailor. Because he is not very comfortable on land, Seaspray does not do well in ground fighting. On the water, however, he has few equals.
His alt-mode is a Hovercraft.
