Lol it's alright XD I think you nailed it though, moves like that that hit multiple times are natural but I guess if there's no additional input needed than it's auto?
A Naturall Combo is essentially Two or more Strikes where if the first one hits.... The Rest is Guaranteed..... the input is irrelevant. A Natural Combo is a Natural Combo regardless of if it takes one button press or multiple button presses.
What I think @KasumiLover69 wants to know is.... what do you call it when a Single Button Press results in Multiple Strikes ?
In other words when you input Phase 4's PPK.... even she herself can't stop Kicking more than Once..... all three Kicks come out despite pressing K once.
They're just Natural Combos, some moves become natural combos on CH even, Jann Lee's 4KK is an example, the majority work on normal hit though, every character's PP string in this game is a natural combo, moves like P4's PKK follow the same rule, like Jann Lee's DS 6P+K or Helena's flappy hands.
A name for those moves in specific though? Hmm... I don't know. In KI, they call them ''auto doubles'', you press a combination of buttons and you get an auto combo. Maybe you could go with that, lol.
