Ku'Shao uses Rage that increases 5 per attack or damage taken.

Passive: Adaptive Shell
Whenever Ku'Shao initially takes damage from any source
he gains 1 Armor or 1 Magic Resist depending on the damage type.
Adaptive shell cannot adapt any further if recieved from the same
target and each stack only lasts 120 seconds

Q - Advance!
Ku'Shao charges a short distance and knocks aside enemy
units that he comes in contact with,
but stuns the first champion that he hits.
If Ku'Shao hits a wall he will smash through
it and his charge extends
for half the initial dash.

W - Strong Arm
Active: Kushao can throw a held tree and deal damage in an AOE.
Passive: When Ku'Shao charges through a wall he grabs a
tree which increases his damage by (+0.78 AD) and
increases his range by 300 within 4 strikes or 6 seconds.

E - Vanguard
Ku'Shao can temporarily deploy a set
of spikes that would reflect damage back to an enemy
unit or monster and shield him for 4 seconds.

R - Destroy!
Based on the amount of rage Ku'Shao has stored up
he channels for a short time which he can then leap
to a distance and land on an enemy unit or hero.
The unit is then captured by Ku'Shao's gigantic claws
and can be thrown within 2 seconds in a range of 600.
The thrown unit will stun in an AOE. The stun length
is based on the remaining rage Ku'Shao has left with
the maximum being 3 seconds.

Data Log:

Day 5: I finally reached the site and started exploring the newly uncovered ruins in Freljord, why the Institute sent me, I will never know. But then again I am the prodigal explorer.

Day 8: The ruins seem to contain runes that don't match any Freljord symbols ever recorded in history.

Day 12: I have done some research and found that these markings seem to resemble markings of the Void.

Day 23: These ruins are bigger than I initially thought they would be. I brought along a tome which contain any and all information about the Void and found that they seem to match some symbols but there are markings that don't correspond with anything in the book. The only word I was able to translate was "Titan".

Day 24: I have reached the deepest chamber, but something was ominous about it. There was huge and overwhelming stone door at the far end of the chamber larger than even a fully fed Cho'Gath. I must leave and bring back help to open it.

Day 30: I was able to gather some help from the Institute. Together we were a team of 6, 3 summoners and after word got out about this new discovery I had Jayce and Heimerdinger tagging along.

Day 32: We reached the ruins and it's deepest chamber to find the door to be cracked and rumbling. We quickly set down our gear and prepared for battle, as we stood in a battle stance we felt wind blowing towards and away from the door in a rhythmic motion like it was breathing. We heard a bellowing roar that echoed throughout the ruins then the door burst open which knocked out Jayce and a summoner Heimerdinger set up some turrets to suppress the beast while I tended to the wounded, the remaining summoners started to channel a spell. The beast seems to be unbothered by the turrets and lifted his huge arm to slam on to the ground but before his arm impacted the ground, he vanished.
I look around for the 'Titan' only the summoners explain that they sent him to a containment chamber back in the institute using a transportation spell. What ever this 'Titan' is. It is a magnificent discovery.

Day 40: I arrive back at the institute to hear hustling and bustling of excitement among the summoners and champions alike. I look at the Newsboard, "New Discovery: The Titan of the Void".

This needs a cap man. I would suggest cap it at 15/25/35/45/55/65 for every set of 3 levels he has.
Then it would be fine.

Q - Advance!

So by the sounds of this, the first target is stunned AND gets knocked aside (assuming to wherever he was angled against Ku’Shao)?
What does this scale by?
This could work.

W - Strong Arm

Active - How can you get trees? Does he recharge one every couple of seconds? Is he a void champion based on trees/nature? You can’t manipulate trees of the forest on the Map like Dota2.
Passive - Right, just read this. So, his next auto attack will be buffed with the active aye? The downside is that, Strong Arm appears not to be able to be cast without charging through a wall.
What does this ability scale by? Only +0.78 AD?
This has some potential.

E - Vanguard

“Reflect” damage? Does he reflect the same amount back in the same type of damage? Does this reflected damage reflect only 1 ability/autoattack or many within a duration? What does the shield scale by?

R - Destroy!

Rage has a maximum cap of 100. You say that the ability is based on the Rage he has, so he does not have to be at full Rage to use this right?
Can Ku’Shao move when he has ‘the unit captured in his gigantic claws’? Also, it sounds hella cheesy.
So during the 2 seconds does his Rage bar decease rapidly to determine the length of the stun right?
What does this scale on?
This ultimate could work, but it seems like an ultimate in-between Skarner and Lee Sin’s.

My thoughts are: His kit will allow him to be a great jungler since he can dash through walls easily assuming over jungle camps to gain a ‘tree’ for extra damage, but his Q, if the dash radius isn’t that great makes him somewhat weak at wave clearing. His E makes him less of a farm jungler and possibly one that specialises in counter-jungling since his dash can charge up a tree over a wall to the enemy jungler in his jungle. His E is good in this case to avoid/reflect damage that may be used in panic from the enemy jungler. His kit seems to be very much about ganking too, especially with two dashes (Q & R) making him very mobile. I can imagine this kit being implemented on a tank/fighter. Note that “Ku’Shao” sounds very Asian and not as Void-like. I would call him something like Rek’Qor to make it sound more like he Rek’s havoc.

I had an initial concept here:
