Could Goku have killed hirudegarn as a ssj2 If...

If Goku had realised it's weakness at the time(anger draining it's Ki), would he been able to kill it without going SSJ3?

It depends on whether you consider Dragon Fist a Ki attack or a physical one. I believe that SSJ3 brings out his strength and puts strain on his body, which means he doesn't have much power to create a Ki attack, and that the dragon was a nice visual effect for a punch. If it's a Ki attack, then I believe SSJ2 would have been capable of destroying Hirudegarn through his weakness, because Goku still had some power left. However, you can blend things and consider that Goku powered up to his fullest as a SSJ3, since that was a possible scenario against Kid Buu, even if not realized.

Is it really 'anger draining its ki'? iirc in the original version his weakness is that he is tangible when he attacks. I don't think he could kill him with SSJ2, even if he discovered his weakness.

To me more mathematical, you could say that Goku's speed doesn't improve so much with SSJ2 that he is allowed to attack when Hirudegarn is tangible. Now with SSJ3... It's four times the increase!

I. Hildegarn's "weak spot" is to attack him while he does so you interrupt him during a move in which he normally does not teleport (which he probably still could).
II. Hildegarn is incredibly resilient, Gotenks even DID hit him. So no, probably not. But maybe with a SSJ2 using even more power.

So that's where Obito got his shtick from.

I doubt it. Gohan was fully blasting Hirudegarn's lower half body in the beginning of the movie, and it didnt seem to do much. I'd guess Goku in ssj3 just happened to hit a weak point the moment the monster attacked.

I doubt even Gotenks blasting it did much. It was probably just Hirudegarn's way of adapting by evolving wings to make it easier to close the distance on the fighters
