It is important to note that in the context of the comic book universes, both the Asgard army from Marvel and the Atlantis army from DC are purely fictional creations and their abilities and strengths are determined by the writers and artists who create their stories.

Assuming that we were to compare the armies based on the information available in their respective universes, here is a hypothetical scenario:

If the Asgard army from Marvel and the Atlantis army from DC were to engage in battle, several factors would play a role in determining the outcome.

Firstly, the Asgard army is composed of powerful beings known as Asgardians, who possess superhuman strength, durability, and longevity. These beings also possess a wide range of mystical powers and abilities, including the ability to wield powerful weapons such as Mjolnir, the enchanted hammer wielded by Thor.

On the other hand, the Atlantis army is composed of the technologically advanced Atlanteans, who are highly skilled in combat and possess advanced weapons and technology. They are also able to withstand the pressure of the ocean depths and possess the ability to breathe underwater.

In a hypothetical battle, the Asgard army may have the advantage of their powerful abilities and enchanted weapons, but the Atlanteans would have the advantage of their advanced technology and underwater capabilities. The outcome of the battle would likely depend on the strategies and tactics employed by each army, as well as any unforeseen circumstances that may arise.

It is worth noting that in comic books, the outcome of battles is often determined by the writer’s creative vision and can be influenced by other factors such as plot twists, character development, and crossover events. Therefore, determining the winner in a hypothetical battle between the Asgard army and the Atlantis army is not a straightforward task and ultimately remains open to interpretation and speculation.
