Princess Undina[2] is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She is an aquatic mobian and the princess of Meropis.




In the past, Undina studied to become the priestess of the Eusebes Shrine alongside her friend Coral the Betta. While Coral ended up being chosen over her, Undina did not hold it against Coral.[3][4]

Undina eventually left Meropis to study in Spagonia, though she grew bored there and decided instead to go travel the world. During her trip, Undina met Honey the Cat in Empire City and decided to model some clothing she designed.[4] Undina also watched the Chaos Emerald Championship before leaving to continue her worldwide travels, visiting other cities such as Shamar and Adabat.[5][6][7] Unfortunately, the princess was apparently kidnapped by pirates who held her for ransom.[4] However, the captain of the crew, Shellbreaker, found out that she could read old sea charts that Abyss the Squid had left behind. Realizing her worth, Shellbreaker did not collect the ransom on Undina from Meropis and instead had her translate more of the charts.[8]

The Case of the Pirate Princess

Undina was later found aboard the Setting Dawn by the Chaotix, Lieutenant Echo the Dolphin, Razor the Shark, and Crusher the Chao, though she was unharmed and seemed be a member of the crew. She revealed to Vector that she had, in fact, been kidnapped by the crew of the Setting Dawn, but they had changed their minds about ransoming her when they learned she could decipher sea charts leading to ancient treasures, due to her prior training as a priestess. At first, Undina happily cooperated, finding it convenient that she could travel the world for free while also preventing the pirates from hurting anyone.[8] However, when it appeared that the item they were searching for was in fact an ancient weapon, she quickly became more hesitant.[9]


Powers and abilities

As an aquatic Mobian, Undina is capable of aquatic respiration, allowing her to breathe both on land and underwater.
