Apex Legends/Titanfall Theories (Lore)
Richter and Gibraltar are related?
I'm pretty sure that Richter, the Titanfall 2 boss and former Apex Predator, is somehow related to Gibraltar: maybe his uncle or something. They're both Maori/Samoan and look similar.
Ash and Renee Blasey knew each other?
Simulacrum Ash and Renee Blasey are both from the planet Typhon and they were both IMC Senior Science/Phase Shift Pilots. If Ash ever becomes a playable Legend, she may recognise Wraith as Renee Blasey, however we do know that as Wraith learns more about her past, she is actively trying to avoid becoming the person she once was (Renee was described as stubborn, obstinate and similar to Caustic in personality).
Lowell's children wanting revenge on Revenant?
We know (from a S4 BP loading screen) that when Revenant was rogue, he raided a number of Hammond facilities and in one of his raids he tortured an employee called Lowell who was "snivelling about his kids". Revenant had brutally injured him, as he described how he "ran his finger down a tendon", forcing Lowell to say Hammond supplied the parts. Revenant then proceeded to say he would send Lowell's parts to his children, which may invoke another Loba-like Legend coming to the Games in the future.
Bangalore knew Renee Blasey?
Bangalore was an IMC rifleman during the Frontier War and Renee Blasey was a senior science pilot for the IMC. It's possible they knew each other but not as possible as Ash knowing Renee, since Bangalore and Wraith are from different home planets.
Loba's father former Militia/IMC operative?
Marcos Andrade was somebody the Mercenary Syndicate wanted dead, therefore they sent Revenant after him. The fact that they sent one of their best operatives to murder a man just because he is a con-man and thief seems absurd. He must have had some sort of information the Syndicate didn't want to become public information, therefore they silenced him. Why would Marcos be heavily guarded as well?
Jack Cooper a future Legend?
This isn't a theory this one is just a wish...
