Need some concept help.

So i'm working on a superhero type champion and I have the lore and am working on the background, but I need help with the kit. I've had a bunch of ideas, but am really not sure if I want to go with them. If anyone has any suggestions or way to improve the champion, i would appreciate it.

I'm hoping for an ad brawler type feel, because ad is more physically interactive then ap, but will take any good ideas.

This is somewhat what i want him to look like.

some concepts.

Gravitational punch. Punches through dimensions. It's a skill shot that the champion punches so hard that it creates a rip in space, like a black hole and at the end of the skill shot his fist appears out another black hole and hits any target hear by. Gives vision.

Tackle. Basically a skill shot that tackles one enemy. As you add more skill points your champion you can tackle more and more people.

Energy scythe. The champion is empty handed, but his skills create a scythe that is used every time a skill is done. The ultimate would be the scythe forming for a longer duration and all the skills gaining a boost.

A passive that lowered all life steal from champions. Up to 75% in a 1v1 and 100% if you are outnumbered. 50% if in a team fight.

A skill that like the scythe, is without any weapons, but when used a corporal, I hope I'm using that word correctly, crystal type shield appears to block skill shots and such things.

Energy powers that draw out the crystals thing into a formation. So double tapping q would form blades on him then q again for a three hit combo. W a bow. E a shield. R a scythe.

Brute force brawler. So like q would be three punches. W would be something like a grab and throw double tap. E defensive build. R a terrain move that lands a punch on a target. And combinations of he skills.

Another brute force brawler with different moves.
