To those saying that Halo wouldn't be able to properly use the Halo Rings: One Forerunner Dreadnought destroys Sol, Traveller is wiped out along with everything in the system, everything. Halo Universe then uses a Star Road to travel to another Galaxy. Activates the Halo Array and all organic life within the Milky Way is obliterated. That includes the Vex because they have organic mind cores. That's just one of Halo's weapons and how they could effectively use it. Edit: Below is just some information on the Star Roads, this also shows you the power of The Flood: During the last decade of the Forerunner-Flood War, it was revealed that the star roads were not completely inert. Having amassed a sufficient level of sheer intellect to elevate them to a state of transsentience, the Flood's newly-developed Key Mind intelligences began to take control of star roads, along with other once-inactive neural physics constructs, and wield them as weapons. The star roads, in their weaponized form, were incredibly powerful, being capable of either physically tearing apart astronomical bodies and Forerunner Fleets interfering with Forerunner slipspace travel as well as generating suppression fields to disable Forerunner weapons, ancillas and shields. The Flood moved star roads across interstellar distances by using the Precursors' neural physics-based method of superluminal travel, which they also utilized to transport their converted vessels. The Flood-controlled star roads warped reality around them which not only enabled organic beings to feel when they were nearby, but also mutated space-time and converted slipspace to be unsuitable for Forerunner transit. The Flood configured star roads to various formations when using them as weapons. One common star road configuration was shaped like two parallel double-arcs, over 50,000 kilometers in diameter, and contained thousands of interwoven star roads. In the center of each double-bow was a point of inky darkness surrounded by a glowing ring. These structures had a constantly fluctuating apparent mass, and were seemingly nonsolid. These double-bow configurations were capable of destroying planets by wrapping around them and causing the planet to crack and shrink; Uthera Midgeerrd was destroyed in this manner. It was theorized by Maker-of-Moons that the Precursors moved stars the same way, by forcing changes on their orbits with star road formations. In many engagements near the end of the Forerunner-Flood war, star roads were used to trap Forerunner forces that were soon overwhelmed by the Flood. One example of this is the Battle of Kan Pakko in which the Forerunners were defeated by the Flood due to the star roads' influence. The Flood used star roads to destroy entire systems, leaving only dust and rubble in their wake. The IsoDidact witnessed nine systems destroyed in this manner. The star roads were also used by Mendicant Bias to trap most of the surviving Forerunners during the Battle of the Greater Ark , using the filaments to form a large "wall" around the Ark before slicing the structure apart along with Omega Halo" [spoiler]Halo shitstomps Destiny[/spoiler]

Everyone here talking about oryx taking Spartans. Two words. Halo rings. Spartans wouldn't even have to set foot on earth, or any planet at all.

Halo 2 LASO sniper Jackal would kill everyone blindfolded.

Halo, clearly. Not only are the Spartans stronger but if the universes collided then there's no way they wouldn't also be guardians. They're already suited for the classes. John and Fred are clearly Titans, Linda is a warlock, and Kelly and Buck are Hunters.

destiny has the hive halo has the flood completely different destiny has ghost halo has 343 guilty spark destiny has pikes halo has ghost you already said gho- i know what i said! destiny and halo completely different

*goes back to when the halo 1* *activates rings* *all of the destiny universe gone*

I would say destiny But the only way destiny would win would be to kill them both So oryx just kills everything Then takes the halo universe And adds it to his dreadnought

Oryx can just take all the spartans. They don't have light.

I'd rather see the good guys of destiny and halo fight the bad guys of destiny and halo. Think about it

*Crota talking to his dad over the phone* Oryx: "Are you sure your throne world is secure son?" Crota:"Yeah dad I've got it covered" Oryx: "Ok just be wary about those guardians" Crota: "Oh we've had a breach hold that thought oh god is that...cheese on my bridge?" Oryx: "Son get out of there now!" *In the background Crota can be heard fighting guardians* Crota: Oh God not cheddar PLEASE NO ARRRGHHHH *Crota screams as he has cheese pushed up his ass and down his throat* *XxX420mlgXxX picks up phone* XxX 420mlgXxX: You're nxt m8 u btr git gud scrub.

The Halo universe wins rather trivially

Assuming that each universe had every possible advantage (excluding the halo rings, because that would pretty much kill everyone except for vex, hive, and flood), and they were in a neutral location with both planate based combat and space based combat, there would be no definitive answer. We don't know enough about the Destiny universe to accurately judge this contest. Even with what little we do know, the entire Halo universe might have a run for its money. Let's wait until we have as much information as possible.

Halo Because the covenant is more intelligent because they glass planets and the fallen just wants to gain power to use against their enemys. And glassing could wipe out a entire planet if there is enough covenant cuisers in minutes while the fallen could take months to gain power to wipe out humanity. And Flood vs Taken? Flood would win because they can infect humanity and covenant while the taken can just take over fallen, hive, vex, and cabal. And flood can use any weapon unlike the taken where they can only use the weapon the fallen, etc. have Sure Destiny is only a year old but still halo would win [spoiler]Spartans Never Die[/spoiler]

Think of halo and all the shit we have to deal with, would you want all that raining hell down on you? Even the flood would wipe you out singlehandedly. The forerunners would definitely decimate you. The enemies of the halo universe are too strong. Oryx can't take the flood as they are controlled by grave mind.
