ZANGIEF
-From startup to 3F, Double Lariat is invincible from the feet up; reaches active at 4F
-From there, a hurtbox appears above the waist and at the feet
-Because of the gap between hurtboxes, if you can properly bait out your opponent, you can counter
Double Lariat's hitbox
SAGAT
-st.HK, useful for armor breaks and anti-air, has a hitbox at the knee for the first hit, and for the second, has a large hitbox from the thigh to the foot
-Because the first hit is 5F and the second is 7F, you can easily counter simple jump-ins
-The second hit only does 40 damage, so based on the distance, we recommend using the unique attack Step High Kick (F+HK)
-
Step High Kick → EX Ground Tiger Shot combos for
220 damage, 300 stun
st.HK (1st hit) hitbox
st.HK (2nd hit) hitbox
DAN
-Specific numbers for Dan's normals missing from the last blog:
st.LP recovers 4F faster, +7 on hit
cl.HK recovers 4F faster, +6 on hit
-Hitboxes are the same as in Super
st.LP's hitbox
cl.HK's hitbox
-nj.HP juggles and causes known down, so
HP Koryuken → FADC → nj.HP combos for
240 damage, 400 stun
DUDLEY
-EX Ducking is upper-body invincible from startup to 14F, completely projectile-invincible
-Follow-ups are possible from the 3F, and since they juggle, you can do various combos
-Example:
cr.HK → Ducking → Ducking Straight → EX Ducking → EX Ducking Upper (296 damage, 480 stun) is possible
-After EX Ducking in the corner, you can connect Corkscrew Cross, so try using EX Ducking
EX Ducking's hitbox
HAKAN
-Oil can last for up to 30 seconds in AE (15 max in Super)
-After Oil Slide, the Kick follow-up Oil Shower added. Same oil time as LK Oil Shower, puts Hakan at +14
-Oil Rocket's hitbox is noticably larger when oiled than when dry, so if you have the chance, oil up
Oil Rocket's hitbox (Normal state)
Oil Rocket's hitbox (Oiled state)
ADON
-st.LP's hitbox is larger at the fist, while the hurtbox was cut to the elbow
-st.MK's hurtbox at the foot is significantly reduced
st.LP's hitbox
st.MK's hitbox
-cl.MK forces stand on grounded opponents, so combos with it are easier to connect (no changes to the hitbox, however)
And that wraps up the AE development blog and character guide.
