You're confusing Hsu Hao with Jarek. Jarek was the MK4 Kano clone. Hsu Hao actually had unique moves. His thunderclap was actually a really sick move, highlighted how powerful he was
Welp. The fact that I didn't know that is a testament to how forgettable he is. Should forever R.I.P tbh. But, in terms of visual design, he's basically a Kano copy. There's no point of him. Kano has the chest laser now. We don't need 2 shirtless villains with lasers in their chest.
And it looks like Jax has a thunderclap in his Fatal Blow. They could give Jax a thunderclap and then boom. Hsu Hao. There are just BETTER 3D era characters that I'd rather see. But, to even compare Jacqui to Hsu Hao is just hating. The fact that Hsu Hao is known as the worst character and one of the biggest memes in the franchise (While I've seen a ton of people coming around to Jacqui in MK11) is just facts.
Could NRS somehow manage to make Hsu Hao cool? Sure. Would I want to see that anytime soon? Nah. There are too many 3D era characters that could do with that chance before him tbh.
Ashrah, Fujin, Havik, Hotaru, Nitara, Sareena. These are all characters that I think would benefit more being brought back. There's a lot more they can do with them especially when it comes to story etc.
Havik and Hotaru especially. I don't think we've seen anything with Chaos Realm or Order Realm in the current timeline and they could do lots of cool shit with them.
There are just other characters with more interesting designs, story possibilities, etc, than Hsu Hao.
