The planet Sakaar was first seen during the ‘Planet Hulk’ storyline in The Incredible Hulk.
The Hulk was sent on a space mission on behalf of S.H.I.EL.D. Once the mission was completed and the Hulk was on his way back to Earth, it was revealed that the Illuminati ( comprised of Dr. Strange, Iron Man, Reed Richards, and Black Bolt) commandeered control of the S.H.I.E.L.D space shuttle and prevented the Hulk from returning to Earth.
The shuttle was reprogrammed with new coordinates to a planet that was idyllic and uninhabited so the Hulk could do no harm to others and live a peaceful existence elsewhere.
However, due to unforseen circumstances, the shuttle headed towards a portal and the Hulk landed on Sakaar.
The despotic Red King rules the planet Sakaar with an iron fist.
Fans of the Marvel Cinematic Universe know the planet Sakaar was featured in Thor: Ragnarok.
Some plot points from the ‘Planet Hulk’ storyline can be seen in the big screen blockbuster, with a few minor tweaks.
For example, the Grandmaster rules the planet Saakar.
Thanks for joining me on the journey to Sakaar and enjoy your Sunday afternoon!
