Hellfire Blast, called Crimson Thunder Wave (雷紅波 raikōha) in the Japanese version, was introduced in Tekken 5 as part of Devil Jin's movelist. This move is similar to Devil's Inferno attack, but the Hellfire Blast is much faster than Inferno, and instead of shocking the opponent, it forcefully knocks the opponent to the ground. Notably, while Inferno had a range limit, Hellfire Blast will extend through the entire screen, although at farther distances there's a chance that the move will wander upwards before it reaches the opponent, therefore missing them.
Hellfire Blast is a "high risk - high reward" move; though it can take a good chunk of health away, Devil Jin is at the mercy of the opponent if he misses. In most cases, the opponent has enough time to perform their strongest unblockable attack before Devil Jin regains control. The user can angle Hellfire Blast to the left or right by pressing Up or Down respectfully. Doing this slightly shortens the recovery time, but the user needs to be very close to the opponent to connect this way (or, on the off chance that the opponent side-steps in the same direction, it can be used at a distance).
Hellfire Blast can be avoided by simply crouching or sidestepping. For Jack models, they can recover some health after being struck by this move.
