Atlantette

Atlantette is one of the main characters of the Ink Globs of Doom, and is also the rescuable character, until the DLC release. She was once an innocent mermaid girl that Astra adores her the most, and is protective of, until that vile devil came by and kidnapped her into his own army of robots, built for evil. She has been forced to fight her friends who turned against her and now managed to defeat that evil devil for good, thus turning everyone who served him back to normal. After the event of the robot apocalypse, she turned over a new leaf by becoming an ally to Astra, as well as continuing to serve to her family in the Atlantis City.
