Air hk tatsu.
lp/mp shaku looks like hp but recovers faster. Useful for not getting hit by jump-ins. MP srk does slightly more damage than hp srk when it connects as an anti-air if hp srk would only hit twice. You can use mk tatsu in FADC combos, not sure if it works with hk tatsu.
Define ‘ultra option.’ Demon punishes lots of shit and does ridiculous damage. Demon Armageddon’s useful but it doesn’t have the utility of Raging Demon.
It’s a gimmick.
Lol no. Learn to plink, it’s a 2 frame link.
It’s not 100 damage unless you’re doing a short combo like cl.hp xx lk tatsu, hp srk.
There are character specific setups to stuff reversals with demon flip dive kick.
Crossup tatsu beats most shoryukens when timed properly. And crossup tatsu leads to… another sweep!
Akuma’s vortex got nerfed pretty bad when demon flip palm stopped being an overhead but you still have plenty of good oki options between throws, j.hk, crossup tatsu, lows, and the occasional f.mp.
When you end with a SRK, your opponent quick rises from you at a significant distance. if you demon flip or jump, you get hit by a uppercut/anti-air. The best you can do for oki is throw a fireball or dash up and do a gimmicky throw. You can’t even walk up and do a full blockstring.
Don’t take this the wrong way, but you’re just plain wrong about SRK being better than sweep. All the top players use sweep when possible.
