The soldiers in Call of Duty are used to a more earth - bound and human - centered combat. When they meet the alien species in Mass Effect, there would be a lot of cultural and communication barriers to overcome. However, some characters like Soap might be more open - minded and eager to learn about the different species. On the other hand, the Asari from Mass Effect, being diplomatic and intelligent, would likely try to establish peaceful relations with the Call of Duty characters quickly.
The characters from Call of Duty, being mostly military - based, would likely be initially cautious and strategic when interacting with Mass Effect characters. For example, Captain Price might approach Shepard with a sense of respect but also wariness. He would be interested in Shepard's leadership skills and how they handle the diverse alien races. Meanwhile, Shepard would probably be curious about the more 'grounded' combat tactics of the Call of Duty soldiers.
The interactions would be really complex. The tough - as - nails Marines from Call of Duty might have a hard time understanding the concept of biotics in Mass Effect at first. They might see it as some kind of superpower and be both in awe and a bit intimidated. Characters like Garrus would be intrigued by the Call of Duty weapons and their simplicity compared to Mass Effect's high - tech arsenal. And the relationships would also depend on the mission at hand. If they were facing a common enemy, they would have to quickly find a way to work together, which could lead to some interesting character development.
The Asari from Mass Effect would be intrigued by the Ancient technology in Stargate. Their natural curiosity and long lifespan would make them eager to study it. Meanwhile, the Goa'uld from Stargate might see the various species in Mass Effect as potential hosts or slaves, which would obviously lead to conflict. But the more moral characters from Stargate would oppose this and try to protect the Mass Effect races.
If Tali met Naruto, she would be amazed at his ninja skills. Tali is used to advanced technology, but Naruto's physical abilities and unique jutsus would be a whole new concept for her. Naruto would be interested in Tali's engineering skills and might ask her to help create some new ninja tools. Garrus would probably respect Naruto's combat skills and see him as a valuable ally in a fight. And Naruto would be drawn to Garrus's sense of justice.
The Krogan from Mass Effect and the Berserkers from Gears of War could have a really intense interaction. The Krogan are known for their brute strength and warrior culture. The Berserkers are these large, powerful and somewhat mindless (in a combat sense) enemies. The Krogan might see the Berserkers as a worthy challenge and try to engage them in combat on their own terms. This could lead to some epic battles where the Krogan's natural strength and regenerative abilities are put to the test against the Berserkers' brute force.
The more stoic Gundam characters like Amuro might initially be reserved in their interactions. But as they face common threats, they would start to open up and share their knowledge. In contrast, the more outgoing Mass Effect characters like Garrus might be quick to befriend the Gundam pilots and try to get them involved in their adventures right away. They could bond over their shared love for combat and protecting the innocent.
Noble Six would probably be a bit of an enigma to the Mass Effect characters at first. They might be cautious around Six because of their different appearance and unknown abilities. But over time, they could learn to trust each other.
If a character like Miranda Lawson from Mass Effect met Mercer, she would probably be fascinated by his biological makeup. She might try to analyze him from a scientific perspective, which Mercer may or may not tolerate. And when it comes to combat, Mercer could provide a new and unexpected element to the fight. For example, he could use his shape - shifting to surprise enemies while the Mass Effect characters use their biotics and tech. Also, the loyalty and morality of the Mass Effect characters could have an impact on Mercer. He might start to question his own actions and motives in the face of their strong beliefs.
One interesting plot twist could be the combination of Call of Duty's military tactics with Mass Effect's alien races. For example, imagine soldiers from Call of Duty having to fight alongside the Krogan in a battle against a new, powerful enemy that has elements of both universes. Another could be the use of Mass Effect's biotics in a Call of Duty - like urban warfare setting. This would completely change the dynamics of combat as we know it in the Call of Duty world. And perhaps a plot twist where a character from one universe gets transferred into the other and has to adapt to a completely different set of rules and technologies.
Shepard from Mass Effect might initially be very cautious around the Crysis characters. Given Shepard's military background, they would likely be sizing up the situation and the capabilities of the Crysis characters. For example, if faced with a character in a nanosuit, Shepard would be curious about its technology. Meanwhile, the Crysis characters would probably be in awe of the diverse alien races in Mass Effect. A character from Crysis might be shocked to see a Krogan for the first time and initially be on guard.
The perk system from Call of Duty Infinite Warfare could be introduced to Mass Effect. Characters could earn and equip perks that enhance their abilities. For example, a perk could increase biotic power damage or reduce the cooldown time of tech abilities. In terms of mission structure, the linear mission design of Call of Duty could be blended with the more open - ended exploration missions in Mass Effect. There could be more focused, action - packed segments within the larger exploration - based Mass Effect missions.
Naruto might initially be confused by the Reapers. But his natural curiosity would lead him to try and understand them. He could try to communicate with them using his own unique way, maybe through his chakra. If the Reapers attacked, Naruto would respond with his combat skills. He would be very direct in his approach, not afraid to engage in battle.
