Note that this does not exist in Minecraft; it was written purely as a fiction article.Sea Wave is an ancient creeper that lived before Herobrine came. He had a little sister, Dove's Heart, and was overly agressive towards anyone that would get close to her. He has a family connection to Tiger's Roar, but nobody knew except Sea Wave.
Sea Wave had few friends for fear of them hurting Dove's Heart. Where he was around, the creepers and the spiders were at a war of discrimination, and life was tough. Several ancient tablets and scrolls describe Sea Wave as "a territorial rage of the seas". On one of the battled with the spiders, Sea Wave was forced to join, along with his sister.
Neither of them had any battle wounds, but Sea Wave had to fight hard to defend Dove's Heart. In the middle of the fight, a giant tsunami crashed over the spiders and swept them back into their own territory. The creepers won the fight.
Sea Wave disliked Herobrine because he was an unknown species that might of hurt his sister. He died 5 1/2 months after Herobrine came.
