(possible Rebirth spoilers)
I've seen a couple of cutscenes from Rebirth and there's one where a doctor tells Tifa that a Shinra helicopter saved her and that they "aren't all bad". Plus they seem to be setting up that there is a more "Tankie" version of Avalanche in Wutai that might be bad?
I fought the overturned Bahamut simulation in Remake so I want to throw Chadley under the train in Midgar
