Silly title aside, this is actually a useful strategy in some match ups. Some characters can blow up a whiffed superman, obviously this is for those who can't. Also not that great against characters that are trying to stay away from you. This isn't Foxy's Bird Lao that's uncounterable and has no bad match ups, or whatever bird Lao does, but it does make some match ups more manageable for Raiden.
I've found this to be really useful in the Sonya match up, for example. Against Sonya all Raiden wants to do is run away the whole match. If you space it right the jumpkick will beat all her anti airs, so you can keep doing it until she stops trying to uppercut you every time you jump in. If she blocks you end up fullscreen and she has to chase you down again. If she doesn't block she eats 16% and still ends up fullscreen. If she's blocking it every time you can take advantage of that and start throwing in jip and doing tik throws(sending her full screen again) or block strings.
I'm not sure if you can tell from the video, but if you land it at the right height electric fly will go over their head if they block but it will hit them if the jump kick lands.
It also might be hit confirmable, but I can't quite tell. You don't have to cancel the jump kick into the superman, you can do superman doing that moment while you're hanging there after the kick connects and it'll still work.
The jumpkick doesn't have to connect to do super man, so even if they crouch or jump back or avoid it somehow you can use superman to hit them or travel full screen.
I'll get a list of characters that can actually punish this soon. I think that because of the block stun from the jump kick it'll make it difficult for some characters that could normally punish a whiffed superman.
