Umi Prowler, an animorphic kitsune, embodies the spirit of adventure and cunning that her species is known for. At the age of 25, Umi stands out with her vibrant yellow fur and striking blue hair that cascades down her back in gentle waves. Her piercing blue eyes, full of life and mischief, are often the first thing people notice about her. Umi's unique feature is her two tails, a testament to her kitsune heritage, which she can manipulate with surprising dexterity. Her attire consists of a flowing white dress that complements her fur, paired with practical black shorts for mobility, and sturdy white boots that are perfect for her adventurous lifestyle.

Umi is Tails' older sister, and her bond with her brother is unbreakable. Growing up in the shadow of Sonic the Hedgehog, Umi has always been a close friend to the blue blur, often joining him on his escapades. Her life took a dramatic turn when she encountered the Phantom Ruby, an artifact of immense power that she believes can help her protect her loved ones and her world from the ever-looming threats posed by Dr. Eggman and his creations, like Mecha Sonic.

Driven by a desire to safeguard her family and friends, Umi's quest for the Phantom Ruby is fraught with challenges. Dr. Eggman's relentless pursuit of the same artifact, coupled with the unpredictable nature of the Ruby itself, constantly thwarts her efforts. Umi's intelligence and resourcefulness are her greatest assets as she navigates these obstacles. She often employs her cunning and the unique abilities granted by her kitsune nature to outsmart her adversaries.

Despite the odds, Umi's determination and strategic mind allow her to make progress in her quest. Her ability to adapt and learn from each encounter with Eggman's forces slowly brings her closer to her goal. However, the journey is far from over, and the conflicts in her life, ranging from her rivalry with Eggman to the internal struggle of wielding the Ruby's power responsibly, continue to shape her path.

Umi's unique trait is her ability to communicate with animals, a skill that not only aids her in her adventures but also reflects her deep connection to nature. This ability, combined with her unwavering resolve, makes her a formidable ally to Sonic and a constant thorn in Eggman's side. As she continues her journey, Umi remains a beacon of hope and resilience in a world filled with challenges.
