Blaze is a character in the Mortal Kombat fighting game series who made his debut as a background character in Mortal Kombat II. He made his playable debut in Mortal Kombat: Deadly Alliance as a hidden character, and served as the boss of Mortal Kombat: Armageddon.
First introduced in the series as a non-playable character seen in the background of the Pit II arena in Mortal Kombat II, Blaze was depicted as an elemental being from Outworld shrouded in flames. As his name and appearance suggests, he has control over fire, lava, heat, etc.
Blaze's first chronological appearance was supposedly in Mortal Kombat II, visible only as a burning figure in the Pit II background, fighting a character fans have since named Hornbuckle does not come without controversy. Daegon is described in Mortal Kombat: Armageddon as being awoken centuries prematurely, due to Caro losing mental contact with Blaze (because of his imprisonment guarding the last dragon egg) and mistook that for the signal to awake Daegon. Also, in Blaze's Armageddon Bio, Blaze is set free after the egg hatches during the events of Deception, and is unaware that Daegon was awoken prematurely. It's not until Blaze gives the signal to wake both brothers he learns that Daegon had already been freed. If the burning figure in Mortal Kombat II was truly Blaze, that means Blaze had been imprissoned to guard the egg sometime after Mortal Kombat II, which means Daegon could not have been awoken centuries earlier because Blaze would have known. With the Black Dragon dating back to before the first Mortal Kombat and the Red Dragon dating back beyond that, it seems the burning figure seen in Mortal Kombat II could not have been Blaze, since at the time he was already guarding the egg.
