A Little Aesthetic
I've been thinking hard now about Kha and what he does and I realized something others might have already seen: Kha's shtick is eat and evolve right? Where's the eating part? I spent a few hours theory crafting about what could do the trick and I came up with something that seemed somewhat(but mostly not) suitable: A new/remade passive(Don't get me wrong I like Unseen Threat for what it does but I barely take it into account when I play Kha). The following was an idea, please if you see any (major or small) holes in this idea or any notes you want to make, feel free.
Evolving Hunger: If
hovers(stands above/next to) an enemy champion's corpse, after 4 seconds he begins to eat the corpse, acting as a channel for 2 seconds. After eating the corpse he gains a bonus depending on how the champion died
Kill by Kha: 20% of that champion's AD as bonus AD for 10 seconds
Assisted by Kha: 70 Bonus Gold
No intervention by Kha(Kha didn't affect their death): 10% of his current exp bar in bonus exp(Thinking about just halving the 70 bonus gold to have it just 35 here)
While eating Kha is sighted by the champion he is eating for the duration of the meal and 2 seconds afterward.
Cool-down: 60 seconds
Pros to having the munchies: Free gold/Buff/Exp(Depends on champion's death)
Cons to being gluttonous: Can be sited and pinged for a gank, can be caught eating, not too smart to do with a team fight near, leaves Kha open to attacks as he intentionally stands in one spot for 6 seconds where he's not doing anything or he is simply out of everyone's hair for that time allowing someone to escape if chasing.
Thats my 2 cents, have fun tearing it inside out.
"Evolve and overcome."

Side Note: This could just be turned into an aesthetic that just happens to look nice, can have no gameplay effect whatsoever.
