Burning Blaze
From Sonic Retro
Burning Blaze is the name of the Super-like state that Blaze enters in the end of Sonic Rush. Blaze achieves this form by using the power of the seven Sol Emeralds. The name "Burning Blaze" is confirmed by both a Japanese strategy guide and Blaze's profile on Sonic Channel. It is possible that this form may be officially referred to as a "Burning State" due to use of another set of emeralds.
While transformed, Blaze's lavender fur becomes pink, and the red highlights on her ponytail disappear (they turn pink as well). In a first for emerald powered forms, Blaze's clothes also change color. Her purple cape becomes red, and it's pink rim becomes gold. Blaze's cuffs also burn with a pink fire, and she is surrounded by an aura of fire. The name "Burning Blaze" may thus indicate that she is literally on fire.
In this state, Blaze gains the traditional Super State effects of enhanced speed and defense. Blaze loses fewer rings per hit than normally, depending on the power of the hit. Blaze also gains the ability to fly and can use charged dashes similar to the ones Super Sonic, Super Shadow, and Super Silver use. The difference is that the fire from these dashes in behind her opposed to in front of her. While this may seems small, this actually makes her vulnerable while using the dashes. Blaze is also to generate and shoot fireballs.
While Sonic Rush ended with Blaze still transformed, she is not, and does not transform at all in the 2006 Sonic the Hedgehog game. It is theorized that this is because that game may take place before the events of Sonic Rush. However, it's a moot point as that game effectively erased itself from the series's timeline.
