Almighty Tallest

"If you are an Almighty Tallest, then you can command every Irken people in their empire so you can give them their laws and edicts to make them happy and well satisfied, and of course, you can keep them happy also, so if you want to be like that, take a good care of them."

--Su Ji-Hoon, Operation Impending Doom III

The Almighty Tallest are the leaders of the Irken Empire. As the name suggests, he or she is the tallest known Irken alive and has virtually absolute power, besides the Control Brains.

Description
The Irken Empire has a hierarchical class structure in which shorter individuals are both figuratively and literally looked down upon. The tallest Irken born in a specific generation takes command of the entirety of the Empire. However, in the event that two Irkens are exactly the same height, they will rule simultaneously, such as in the case of Red and Purple. In such a case, which is likely rare, the two may or may not take responsibility for different aspects of the Empire, something that may be alluded to by the general attitudes of Red and Purple. What with Red being more outspoken, active, and generally 'in-charge', and Purple generally paying more attention to eloquence, social situations and creature comforts such as food and drink.
