Blaze the Cat

Blaze the Cat is a lavender, female Mobian Cat. Blaze's first encounter with Sonic the Hedgehog was when he found her in captivity after she was captured by a group of SWATbots outside of Knothole. At first hostile to the "Blue One", Blaze eventually realized Sonic meant her no harm after their brief battle ended and he offered his friendship. Blaze vanished soon after, promising to haunt Sonic's dreams as he'd haunted hers.

Search for the "Blue One"
After being plagued by constant dreams about a mysterious "Blue One" that could save her "Sol Emerald" (presumably her dimension's equal to Chaos Emeralds) Blaze from danger, Blaze came to Mobius Prime to seek out Sonic. While exploring just outside of Knothole, Blaze was intercepted by a group of patrolling SWATbots. Although she fought valiantly, Blaze was eventually subdued by the group and taken to one of Dr. Eggman's research bases. The robotic "doctors" found that their scans showed Blaze to not be from this dimension. Blaze awoke soon after and destroyed the bots as well as a part of the facility. There she finally encountered Sonic, who had arrived to rescue her. (StH: #160)

Hoping to make sure that the person before her was truly the one from her dreams, Blaze engaged Sonic in combat. While proving her combat skills and proving a challenge for Sonic, she ultimately lost when Sonic created a vortex around her, preventing oxygen from reaching her to put out her flames. When she began to run out of breath, Sonic stopped and offered his help. Blaze then informed him that she had been looking for him, only to vanish in a blaze of fire, saying she would "haunt your dreams the way you have haunted mine!", leaving Sonic confused. (StH: #161)

Personality
Normally cool and collected, Blaze gives the impression that she keeps a tight lid on her emotions but this may not be her true nature. Despite her calm appearance she can lose her temper easily and when does, she's quite scary to be around. Blaze is reserved, disciplined, somewhat shy, and prefers to build a wall around herself when it comes to strangers. It is also revealed that she is afraid of heights.

Abilities
Blaze is a pyrokinetic, using her ability to manipulate fire and her claws, jumps, and kicks to fend off her enemies. She also uses her pyrokinetic abilities to propel herself in different directions and to protect herself from flames. Blaze turns into a fiery tornado when jumping, similar to Espio the Chameleon, and does not keep speed or go faster. Despite the speed difference, both her blazing tornado state and the traditional "spin ball" forms of other characters function relatively the same. Blaze is uses her pyrokinesis to send different fire attacks from long range, such as blasts of fire and infusing her fire into her physical attacks at close range.

Background information
In the game universe, Blaze seems to have two different backstories as to where she came from. In her debut game Sonic Rush (and most other games afterward) Blaze is depicted as being the Princess of the Sol Emeralds in a parallel dimension to that of Sonic's world.

The same backstory is applied in it's sequal Sonic Rush Adventure which takes place in her universe entirely (Marine the Raccoon also hails from Blaze's world).

However, in her second appearence in the series, Sonic The Hedgehog (2006), Blaze lives in the future where she battles alongside Silver the Hedgehog against the fearsom monster Iblis. At the end of Silver's storyline, Blaze sacrifices her life by sealing Iblis inside her body with the Chaos Emeralds. At the end of the game, it was made so Iblis never existed, causing the events of the game to never happen, meaning that Blaze is still alive.

The possibility that she and Silver now never even met each other is never clarified, as in all future appearences they both appear in seperate games from each other (storyline wise) and neither of them ever mention each other in their respective games. Though it's still likely they do know each other, as they both seem to be chasing Eggman Nega in there respective games. Wether or not there friendship exists in the comic universe is currently unknown.
