Introduction
Akuma (also known as Gouki) is the brother of Ryu and Ken's master, Gouken (Sheng Long). He is a more powerful version of Ryu and Ken, and was a secret character in ST. He is somewhat of a secret character in HDR as well, however there is no code to choose him in Remix mode. Simply input up from Honda's character select image, and Akuma will be available. Akuma is not available in Classic mode of HDR (ST), even with the code. He has the weakest stamina in the game, and is much weaker in HDR than he was in ST, but has been given a Super Attack, the Raging Demon. Akuma is banned in almost all HDR tournaments due to his overpowering Air Hadoken, Normal Attacks and Super Attack. He is a fun character to play with though, and does not win easily if the player does not know what he is doing. Though he has a health handicap (he can be almost KO'd from perfect with one Super combo), he can dish out a lot of damage with his juggles, meaty Air Hadoken setups that can lead to mixups and an almost inescapable Raging Demon setup. It is widely considered that Akuma is still the strongest character in the game, and that he is just barely broken.
Changes From Super Turbo To HD Remix
Health handicap and dizzy
Akuma now has the lowest stamina in the game and can be dizzied, where in ST he could not be dizzied. A regular 3-hit BnB combo from any character that would usually do about 25% damage on average against other characters, will do about 50% damage on average against Akuma. He can also be KO'd from perfect by Super combos such as Ryu's 9-hit Super combo (cross-up RH on a crouching Akuma, Rushing Fierce, cr Fierce, Super).
Normal Kicks
Akuma no longer has invincibility on his cr Roundhouse and cr Forward. He also no longer has a stray hitbox on his Medium Kick.
Hadoken
Akuma's Hadoken has slightly more startup time than ST Akuma, about the same as Ryu, but has slightly faster recovery than Ryu. Fierce Hadoken now knocks down only from close range, where in ST it could knock down from full screen.
Flame Hadoken
QCB Punch
Flame Hadokens also have more startup than they did in ST, and the motion has been changed from HCF Punch to QCB Punch. The recovery is also much slower; he can’t do his corner lockdowns anymore!
Air Hadoken
It now has a slightly more vertical angle than it did in ST, and also causes Akuma to "bounce up" in the air when he releases it. This bounce allows Akuma to cross-up a knocked down opponent. Akuma can also perform the motion as a TK motion: QCF, UF Punch. This allows him to perform an Air Hadoken very close to the ground, just as he jumps into the air, similar to a Juice Tatsu.
Tatsu
It no longer has any invincibility whatsoever.
Teleport
It can now be done with PP/KK instead of PPP/KKK. It also has some vulnerability in the upper body area now, though it is still invincible-on-startup and during recovery.
Raging Demon
Jab,Jab,F,Short,Fierce
It is completely invincible for almost its entire duration, except during recovery which is a small window to punish. It is immune to throws, and cannot throw airborne or invincible opponents or opponents who are in their pre-jump frames. Some players believe that it can randomly throw pre-jump frames about 25% of the time, though this has not been concretely proven with empirical evidence. But there are some times when his RD setups are certainly inescapable, especially when executed after a meaty Air Hadoken.
