Compared to the rest of the Mass Effect 1 Normandy crew, who are all relatively young, Wrex's age sets him apart as a unique and interesting character to interact with. In certain interactions with other crewmates, Wrex seems to take on almost grandfatherly role, particularly in regards to Tali. By comparison, Wrex is hundreds of years old, and Shepard can talk to him about his personal experience on his homeworld and his time spent as a mercenary. Although he was provided with memory imprints of Krogan history, his personal experience is nearly nonexistent at the start of the game. His growth inside the tank lead to rapid development compared to standard members of his species. Grunt, when Shepard first encounters him, is only weeks old at most. One of the major differences between Wrex and Grunt in Mass Effect is their age and experience. Why Wrex Is The Better Mass Effect Companion Both companions also appear later on in the Citadel DLC. Although Grunt makes an appearance in ME3, provided he's still alive, his role in the game isn't as extensive as Wrex's.

If Shepard chooses to free him from his tank, they can earn his loyalty to ensure his survival through the ending of ME2. Players first encounter him as a tankbred creation of Warlord Okeer, meant to be a perfect specimen of the Krogan species. Grunt can be recruited to accompany Shepard on the suicide mission in Mass Effect 2.

Wrex remains with Shepard until the mission on Virmire, where players may be forced to kill him if they haven't leveled their charm or intimidate skills high enough. From there, they're given the option of letting him become a part of the Normandy's crew up. There, he can team up with Shepard to take down an agent of the Shadow Broker, Fist.

Players can encounter Wrex on the Citadel in ME1, during Shepard's first visit.

But which of the two is the better companion? These characters have vastly different backstories and personalities, and depending on Shepard's choices, both can have a strong presence in later parts of the series.

Throughout the course of the Mass Effect trilogy, players are given the opportunity to recruit two different Krogran to become part of Shepard's crew: Wrex in Mass Effect 1 and Grunt in Mass Effect 2.
