Mundo Has A Brother???
Let's start with a piece of his lore:
He followed the noise as carefully and quietly as he could - wouldn't want to spook the patient into running away and infecting even more people - and found exactly what he was looking for.
A young boy. No older than fifteen, probably, with a shock of white hair and a large metal sword-looking-thing in his hand. He had some sort of hourglass tattooed onto his face. Maybe a warning? A symbol that he was not to be approached under any circumstances?
Mundo knew he'd found him.
Mundo knew he'd found him. Patient zero.
It would be a complex operation, requiring skill, planning, a careful eye, and---
"YOU MIGHT FEEL A LITTLE STING", the creature said, leaping out. His enormous purple form hurtling through the air, massive cleaver in hand, tongue flapping in the wind.
The boy was surprised, but not unprepared. Anybody hanging out in the Sump knew to be ready for trouble at a moment's notice, and the kid had plenty of time to prepare.
Nothing but time, in fact.
No two ways about it: this was a troublesome patient.
He refused to answer Mundo's questions about his medical history, and repeatedly evaded Mundo's attempts to make him take his medicine. He repeated himself over and over again (perhaps suffering from a case of physical amnesia?) and had no respect for Dr. Mundo's authority.
The two scuffled over the child's sickness for what felt like hours. Mundo made what he thought were very salient points about the merits of treatment, but the child constantly evaded Mundo's attempts to help him.
Mundo grew tired of arguing with the boy. He mustered up one final attempt at treatment, wielding his precision scalpel with the artistry of a Demacian duelist. The words of his medical vows - "MUNDO FIX ALL THINGS, MUNDO DO MEDICINE VERY HARD" - ran through his head again and again. His desire to cure this child filled him with purpose and determination.
He swung with all his might.
The treatment was a success.
But then - somehow - the treatment reversed itself. Whatever good Mundo had accomplished in his last attempt at a cure was suddenly undone. To Mundo's utter confusion, the child scurried away, utterly uncured.
Mundo screamed in irritation.
"WHY CAN'T MUNDO SAVE THEM ALL?" he screamed to the sky.
Sounds interesting no? If you didn't catch what was odd there, let me tell you, 
saw go back in time. Doesn't this seem odd to you? Here, let's read some of 's lore;
They trekked out to the old clockwork tower in the heart of Old Zaun, and climbed, occasionally stopping to paint an obscene caricature of a prominent Piltie or two. They were near the top when a handhold gave way causing one of his friends to slip and fall off the spire. Instinctively, as if he'd done it a thousand times before, Ekko activated the crystal-containment device. The world shattered around him and he was wrenched backward through swirling particles of time.
The hair on his arms tingled with electricity. A strange wooziness clouded his mind. Then he saw his friend reach for the rotting plank to repeat his soon-to-be-fatal error. CRACK! The plank gave under the boy's weight, but Ekko reached out and grabbed his plummeting friend by the shirt collar and swung him to a nearby ledge. Unfortunately, he misjudged the trajectory and tossed his friend into the clockwork tower's grinding gears. Whoops.
Numerous rewinds and some adjustments for windshear later, Ekko saved his friend's life. To others, it looked like Ekko had the reflexes of a god.
This proves that others cannot see when goes back in time, so there is something up with . So, what other chamion is out there that might explain this, thats right, 
. He is discribed as having "chrono-displasia. This mystical disease granted him immortality, but detached his consciousness from its anchor in the present time", it says he got this from his research, but I know a more reasonable explanation, he had it from birth! As did his brother, !
Shocked? You should be. I will tell you how this is possible in a moment, but for now, wouldn't it make sense that and were brothers? I mean they both have the effects of the same mystical disease. But then, who are their parents? Well, this was all too easy to figure out...
and 
!
Why? Because one is human and one is from the void, that would explain 's appearance, and how is different. Also, since their parents are from different dimensions, their children must be desynced from the time of the world.
So that proves it does it not? and are brothers.
Come now Rito, did you think you could hide this lore forever?
