Echo ordering the Meropis City Guard to attack the Dark Gaia Creatures, from Sonic the Hedgehog #263.

When Echo and the Meropis City Guard came to their usual morning visit to the Eusebes Temple during the Shattered World Crisis, they found the Knothole Freedom FightersSonic the Hedgehog, Amy Rose, and Rotor the Walrus–trespassing on their sacred grounds.[4] Once it was decided that most of the Freedom Fighters, Coral the Betta and Razor the Shark would be taken their king and queen, Echo was ordered to stay at the temple to keep an eye on Rotor and Pearly the Manta Ray, which she did accordingly. Later the same night, when the shield protecting Meropis disappeared, Echo and the Meropis City Guard were forced to protect the city and evacuate the citizens when it was invaded by Dark Gaia Creatures.[5]

The Case of the Pirate Princess

Echo talking with Honey

Echo questioning Honey, from Sonic Universe #91.

Sometime later, when Princess Undina went missing during her studies in Spagonia, a ransom was sent demanding money for Undina's return. When no one appeared to retrieve the ransom, Echo was assigned by the King and Queen to search for Undina. Her first action was to interrogate Professor Dillon Pickle at Spagonia University on Undina's whereabouts, who mentioned to her that Undina had departed to Empire City. There, Echo discovered Undina had briefly partnered with Honey the Cat to advertise Honey's fashion line. Echo learned from Honey that Undina had decided to embark on a world tour. After receiving information from an anonymous source, Echo learned that the princess was last spotted somewhere in Westopolis and the ransom demand came from pirates. However, Echo's lack of familiarity with the city led her to requesting the Chaotix Detective Agency to assist her in finding information at the docks.[6]

With help from Vector, a dock worker named Daryl admitted that he saw Undina with the Pirates heading toward an island called "The Knives". Echo and the Chaotix decide to head to the island with Echo's submarine-convertible car. During the trip however, they run into an unknown construct. Supplying the Chaotix with Air Charms, the group checked outside and were ambushed by Razor the Shark and his chao Crusher. Espio ceased the hostility between the two parties, and Razor revealed that he was also trying to find Undina and the pirates on Coral's behalf. Echo then noticed how odd it was that they ran into Razor where the pirates were, and questioned how Razor also knew about the pirates' involvement. Before she could confirm her suspicions, the pirates' nearby ship caught the group in a cage. The group was then dumped onboard the ship, and the group found themselves confronted by the pirates, Undina among them.[6]


Echo is very dutiful and dedicated, though maybe to the point of being slightly uptight. She also takes her job very seriously as she followed and upheld Captain Striker's orders without question.[5] She seems to also consider Striker's views on others, as she questioned if Razor's activities supposedly validated Striker's suspicions on him. However, she does not do too well out of her element, and has trouble understanding surface customs.[6]
