|Title||Stella di Mare di Nebbia|
|Anime Debut||Episode 146|
The Mist Starfish is an anime-exclusive Mist Box Weapon Prototype created by Verde. When used, many spinning Starfish that emit Mist-Flames are released. Those that break are fused together and create a single but bigger Starfish. Yamamoto and Ryohei managed to defeat them by forcing them to fuse into one and then destroying it.
- Since they were both created by the same scientist, the Mist Starfish and the Lightning Starfish are similar in both ability and appearance.
