Waves of Change
Echo and several of her comrades joined Captain Striker in visiting the Eusebes Shrine, where they were angered to discover Sonic the Hedgehog, Amy Rose, and Rotor Walrus. Given that the trio were guests of Priestess Coral the Beta, who had not received permission from King Puff and Queen Angelica to have them at the shrine, Echo was left to guard the shrine while Coral and the others were taken before the royal family. Later, she led a force of guardsmen back to the shrine in order to help fight off Dark Gaia's Minions. (StH: #260, #261, #263)
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 Striker's orders without question. However, she does not do too well out of her element.
Powers and abilities
Echo is capable of aquatic respiration, allowing her to breath both on land and underwater, as indicated by her dwelling in Meropis without the apparent use of an air charm. Echo carries a trident which is a standard weapon for the City Guard. In addition to being useful for melee combat, this weapon can shoot out a thin laser from its points.
- Echo's name is likely a nod to Sega's Ecco the Dolphin series of video games published by Sega, though the dolphin protagonist Ecco is a male, non-anthropomorphic dolphin.
Echo is a humanoid dolphin of average height. She has purple skin and a white muzzle with a rounded shout and purple dots on her chins which resemble freckles. She has a dorsal fin on the top of her head, the back of her head and her regular back, a caudal fin as tail and has no toes or nostrils. As attire, she wears the standard City Guard uniform which include black shirts and shorts, green additional garments and a golden helmet adorned with shells. She also wears a shell bracelet around her right ankle.
