Sea Serpent

Sea Serpent monsters are the least supported Monster Type, and least populous after the recently released Psychic Type. In the early stages of the game Sea Serpent monsters had a similar relationship to Fish that Dinosaurs once had to Reptiles - Fish were the weaker, lower-level monsters and Sea Serpents were the more powerful, higher-level monsters, or "Big Fish," essentially. This has changed, since Fish have increased in number and utility. Though they are low in number, Sea Serpents tend to be very powerful in WATER-based decks, and they should not be dismissed or underestimated.

Some major Sea Serpents include "Levia-Dragon - Daedalus", "Ocean Dragon Lord - Neo-Daedalus", "Orca Mega-Fortress of Darkness", "Brionac, Dragon of the Ice Barrier", "Sea Dragon Lord Gishilnodon", "Spiral Serpent", "Water Dragon", "Deep Sea Diva", "Reese the Ice Mistress and "Gemini Lancer".

The only support card Sea Serpent monsters had prior to the release of Raging Battle was "Umi", which was replaced in usage by "A Legendary Ocean", a card that no longer supported non-WATER Sea Serpents. With the release of Raging Battle, however, came the Sea Serpent support cards "Spined Gillman", ""Mermaid Archer"" and "Deep Sea Diva", with "Deep Sea Diva" being the first card to exclusively support Sea Serpents. In contrast to early Sea Serpents, which are generally very strong high-Level monsters, the new Sea Serpents and their support focus upon very low-Level monsters and swarming.
