To make matters worse, in his later appearances in the game, Metal Face just loves to rub in the fact that yes, he killed Fiora. Yes, he enjoyed doing it. No, there isn't anything you can do to bring her back. Every time that bastard shows up, you just wanna shove the Monado up his ass, but you can't.He's immune to it. You can't even TRY to avenge her because of that!
Let's face it, Metal Face is a walking Berserk Button for Shulk and co. The worst part? He knows that and loves every second of it.
The Wham Episode on Prison Island. To sum up the party utterly fails to prevent Emperor Sorean's death at Metal Face's claws, barely makes it in time to receive the Monado upgrade from Zanza before Metal Face kills him, too, and when it finally comes time to pay Metal Face back for all the death and destruction he's caused, he doesn't even take the brunt of the new Monado's wrath. Who does, you ask? None other than Fiora, revealed to be Face Nemesis' pilot when she takes a slash to the chest from Shulk. This sets off a Heroic BSOD from most of the party, as much of Shulk's reason for fighting the mechon was to avenge Fiora's death at the beginning of the game, only for her to turn up alive and on Mechonis' side. And the soundtrack at the end? The Main Theme, which is an orchestral remix of Shulk and Fiora's leitmotif, just to twist the knife even further.
A testament to the voice acting in the English version: The sheer heartbreak in Egil's voice when he realizes even his own goddess has turned against him.
Melia watching her people, including her brother get mutated into Telethia. That particular plot point gets even worse when you look at your Relationship chart....
Even worse, several quests after that event have you going back and delivering a Mercy Kill to many of the transformed Telethia. The "Released from Duty" quest is especially heartbreaking.
The quest "I Will Always Remember You" is equally heartbreaking, especially since it follows a chain quest where you reunited two childhood friends. The quest giver in question ask you to not only kill her friend, but also her friend's mother who despite being turned into Telethia protected her and allowed her to escape.
Xord. In the main story, he's nothing but a SmugBrute you take great joy in beating the crap out of. But if you've been taking care to speak to your NPCs, you'll realize that he was Desiree's father.
Dickson's death. Yeah, the guy was a Jerk Ass who literally shot Shulk In the Back, but he was also Dunban's war buddy and one of Shulk's father figures, and there were a few moments where it looked like he might have genuinely had a soft spot for the Colony 9 kids. When Fiora tells Shulk that Dickson's wounds are too severe to survive, the camera stops for a moment on Shulk's face, as if he's shedding a tear as the party heads onward to confront Zanza.
"Looks like the student... has finally surpassed the teacher."
Lunara, the little High Entia Girl that stays at the entrance of Alcamoth every night waiting for her dad to come home.
Seeing the once tall Mechonis in ruins after Zanza mercilessly destroys it. The sky never looks the same. On top of that, Egil fought to his last breath fighting Zanza and saving the party. He also indirectly gives you the opening needed to defeat Zanza. Despite all Egil did, you can't help shed tears for the guy as he goes down with the ship.
