Heroic and just as fearless as Sonic the Hedgehog, Tangle is scrappy and loves to tangle with bad guys. Not intimidated by danger in the slightest, she has a thirst for adventure and excitement. As such, she is capable of heading into mortal peril and face deadly odds, all while wearing a smile on her face and having the time of her life. However, her desire for adventures makes her reckless and prone to jump head-first into danger without a care in the world. She can also be somewhat careless in battle, like using her tail in a way that gets it injured and focusing more on cheering than watching out for enemies.

Tangle is loud and excitable, but also friendly, polite, helpful and open. While having seen and overcome her own fair share of challenges in the form of Badniks, she is a novice hero, and has thus seen little of the more outlandish subjects that exist out there, like a pyrokinetic princess from another dimension who guards fiery Emeralds. While such signs tend to leave her speechless, she is nonetheless quick to be amazed by them.[10] Whenever she sees or reflects on something exciting, she tends to get starry-eyed. When reacting to a sudden sound or event, the hairs on her tail stand up.

Tangle also has a bit of a mischievous side to her. When she played cards with Silver, she would deliberately try to mess with him while using her tail to peek at his cards.
