History
Ro-Nan was leading an army of Kree into fighting the Chitauri when both alien races encountered the entity Gah Lak Tus during battle. He proposed Chitauri Grand Admiral Kalxor to fight their common enemy, but the Chitauri rejected his proposal.[1]
After a failed attempt to annihilate Gah Lak Tus, which had bonded with an arrived entity from another universe,[2] Ro-Nan returned to protect Hala, the Kree homeworld, from Galactus when it arrived.[3]
