Iggy Double Jump
Normally, Iggy can't double jump, since that motion is instead tied to the glider. However, there is a certain glitch that will let you double jump. To perform it, you have to jump while in Stand On, and press up and S on the same frame. If this works, Iggy will do a second jump in Stand Off. This doesn't have much practical use since you can just super-jump s.j.B if you want to hit someone high up, but it's still a fun option to have.
Airwalk Glitch
Another interesting glitch that Iggy can perform. To set it up, you have to jump and airdash immediately before you land. The timing is strict, so it might take a couple attempts. While he's in the airwalk state, he will be slightly above the ground with looping walk animations. Getting hit or using any attack will end the airwalk. However, if you grab someone while in airwalk, it will softlock the game until the round ends. So if you really want to timer scam your friend, this is how.
Star Breaker Glitch
Yet another glitch, though this one is character specific. If Iggy gets hit in the air by Jotaro's Star Breaker at just the right altitude, and you mash while down teching, Iggy will turn invincible and slide across the stage at high speed until eventually stopping in the corner. In this state you cannot move. This glitch softlocks the game until Iggy either does a super or any of his specials, in which case you'll be able to move like normal again.
