"Crush. Kill. Destroy."
All Out War
There were many prototypes, but I was the first and greatest success.
I crushed. I terrified. I destroyed.
I was wired for superiority, but the other units would not bow. My creators feared me.
They decommissioned me.
I will not be stopped. I will not be forgotten.
I will annihilate them all.
Mecha Rengar returns to the hunt
With a mechanical roar, Prototypecrashed into the testing grounds; Prototype hovered above him, victorious but severely damaged. The lab abandoned 09 and documented their findings: the beast’s construct proved inferior to the insect’s.
But 09’s internal memory would not let him forget. He was the true predator. And a true predator always returned to the hunt.

- It has been hinted by Riot employees that could be part of the same universe as the kaiju monster that the Yordles are fighting against. [ | ]
