The Kree Emperor is the titular ruler of the Kree Empire.
The Kree Emperor ratified a peace treaty with Xandar's Nova Prime Irani Rael in 2014, in order to stop a war with the Nova Empire that lasted a millennium.
This peace treaty caused scattered riots to break out across the Kree Empire and launched Ronan the Accuser's campaign to destroy Xandar.
- In the comics, the Kree Empire is actually ruled by a supercomputer called the Supreme Intelligence, which was originally made from the combined minds of the greatest Kree intellectuals and leaders.
