The Illuminati In MCU Explained - What To Expect!
8. Cutthroat Decisions
In their minds, the Illuminati are always making the correct decision for any situation, thinking of the greater good, and serving as the moral compass of any issues that rear their head.
Unfortunately for the Hulk, the Green Goliath was viewed as one such issue.
As part of the lead-in to 2006's Planet Hulk story, the Illuminati boldly decided to exile the Hulk to outer space. After the Jade Giant has caused a heap of destruction in Las Vegas following a gamma bomb explosion, the Illuminati used a Life Model Decoy of Nick Fury to trick Hulk up into the stars to supposedly fix a troublesome satellite.
Once in that satellite, the device turned into a vessel that shot the World-Breaker off to what was intended to be an unpopulated planet. Getting lost on the way to that planet, the ship instead landed on the ravaged war planet of Sakaar - which is where we find the MCU's iteration of Bruce Banner during Thor: Ragnarok.
While it looks like any such exiling of the Hulk is off the table for now in the MCU, this is just one prime example of the sort of cutthroat decisions that the Illuminati have been known to make.
