To meteor with the downB, do you have to manually activate the kick when you are above them, or can you just let it go off automatically when you land on their head? If both, which is the more reliable?
I'm not sure right now if both are meteors or or spikes but it's a situational thing anyway. I'll refer to them as spike right now until someone corrects me or I do so myself.
If you land on someone with the simple dSpecial it always spikes and you will make the ultra stylish jump afterwards.
It also sends your opponent straight downwards.
The manual Kick on the other hand side only spikes if you hit with the outer hitbox of the kick. It also doesn't send your opponent straight down which helps actually getting them besides the stage instead of them hitting the stage.
We have strings and combos for the extra kick spike.
A simple example is bThrow>dSpecial kickspike (you can DI out of this though) which kills very early if your opponent isn't fast enough. Thing is, if you miss you can easily be gimped since you lost your dSpecial and you will need your second jump and a tether or an uSpecial to recover.
I'd say the extra kick spike provides you a higher risk higher reward option compared to the normal dSpecial spike if you want to gimp someone offstage.
I also feel like I have more control over the extra kick.
This reminds me though that we should look into potential gimp combos with the normal dSpecial spike.
I vaguely remember one I found months ago but I'm not sure if that was a true combo or not.
