The Cosmi-Rod[1] was a Kree war-hammer that projects concussive blasts and is given to certain members of the Kree race.
History
The Cosmi-Rod was Ronan's main weapon. Ronan used it primarily to execute captured members of the Nova Corps.
When summoned to the Sanctuary by Thanos, Ronan was warned by The Other to show the Mad Titan courtesy. Annoyed by the vizier's ranting, Ronan used the Cosmi-Rod to twist the Other's head 180 degrees, killing him.

The Cosmi-Rod is destroyed
Once he obtained the Orb, Ronan placed the Power Stone in the Cosmi-Rod, enabling him to use its power. By doing so, he was able to destroy the Nova Corps' entire fleet during the Battle of Xandar. Drax the Destroyer destroyed the Cosmi-Rod with the Hadron Enforcer, enabling Star-Lord to catch the Stone with his bare hand.[2]
Capabilities
Standard
Built from advanced Kree technology, the Cosmi-Rod is an effective tool in battle.
- Concussive Blast: The Cosmi-Rod can fire a blast of concussive force that was strong enough to twist a person's head around 180 degrees and to send small groups of people flying several meters.
Power Stone

The Cosmi-Rod being powered by the Power Stone
When merged with the Power Stone, it has also displayed various other attributes such as:
- Energy Projection: When combined with the Infinity Stone, the Cosmi-Rod is capable of discharging purple blasts of concentrated energy.
- Planet Killer: When combined with the Infinity Stone, the Cosmi-Rod had the potential to obliterate an entire planet, but the stone was wrenched from the hammer before Ronan was ever given a chance to do this.
Trivia
- In the comics, the Universal Weapon is the regular weapon given to the member of the Accuser Corps of the Kree Empire.
