They’re powerful tools, especially Vega’s, but in many cases not completely unstoppable. As usual, the general advice of “play perfect, don’t get caught in them in the first place” applies here, but otherwise, I’ve got some notes:
Honda’s ochio mixups are strong if he’s close. Most characters have tools to prevent Honda from getting that close, so usually the ochio is his way of winning very difficult matchups or expediting matchups he already wins via his very strong defensive tools and hands. The usually way to counter them is to use a strong reversal against the “tick” attempt, e.g. uppercutting the cr.jab or the jump in or whatever it is. In the corner, it’s extremely strong, since he can repeat it again, but again the key is to counter throw or uppercut the tick.
Hawk’s throw loops are extremely powerful. Fortunately, only a handful of people actually know how to pull it off consistently, so it’s not AS serious a threat at Honda or Vega’s wall dives, which are often effective against beginner- or intermediate-level players. The best way to get out is to either bust out a lot of reversals to mess up their timing, or jump out depending on the character you use and the range at which they do the neutral jab. At max range, there’s a small gap between the jab and the grab itself, which lets characters get out via a counter poke or jump or super or what have you. This is true of Dictator, as he has very few jumping frames, so he can jump out outside of corner traps.
Vega’s wall dives are always a problem. Fortunately, anyone with a decent reversal can get out if they have good execution and timing. There are several methods you can use to perform an autocorrect uppercut, depending on the direction in which Claw does the attack, but isn’t a guaranteed out. Good general advice: just block. It’s technically just a 50% effective ratio, so be sure to concentrate on your neutral game as well to prevent getting caught in the first place.
