Shattered World Crisis
Sonar and her team later "rescued" Sonic, Antoine D'Coolette, Big the Cat, and Chip from an ambush from the Midesta Egg Army. After Sonar and her team drove off the Egg Soldiers, they were greeted by Sonic himself, startling the young aspiring heroes. The Shamar Freedom Fighters then aided Sonic's team in rescuing Ehsan, with Sonar assisting Chip and Big in fighting the Dark Gaia Creatures. After Sonic's team left, though, Sonar and Spike contacted Egg Boss Nephthys, revealing their allegiance to her. (StH: #278, #279)
Sonar bears some resemblance to Miles "Tails" Prower. She is a slender Mobian fennec fox with long triangular ears, a fluffy tail, neck-long fur on each side of her head, and purple eyes. She has mainly teal fur and white fur around her muzzle and on the tip. For attire, she wears a pink shirt, black shorts, long black socks and yellow-lensed sunglasses with a pink strap. She also wears white gloves and purple shoes, both with pink and purple ring straps.
Sonar is an agile strike attacker and excellent hand-to-hand combatant, easily subduing an Egg Soldier with one chop to the neck. Aside from physical combat, she possesses ultrasonic hearing and high reflexes, being able to jump down from tall heights and landing safely on her feet.
