This is mainly based off the Batman Game Series e.g. Arkham Origins and Arkham Knight. So this is based off of when Elliott (Batman) dies and sees the people in front of him. Enjoy.
Kaos
"Oh come on, 'The Honourable Knight?' Even I could've made a better name myself!"
"What's wrong Elliott, not even a dark relic can stop me?"
"You know, assuming that the Elemental Gem was already used on you, you can't use it again, I win (Cackling and Laughter)"
"Never mess with a DARK portal master, you never know what tricks me or anyone else has up their sleeves"
"It's time you were gone Elliott, the gauntlet is mine (smiles)"
Mei
"I'll avenge you son…I promise"
"Elliott! Why do have to go out like THIS"
"Me and Snowball will make sure your death won't be in vain, you have my word"
"I won't forget you Elliott, no one will"
Marinette (Ladybug) Tikki
"Elliott, no, not like this"
"Don't give up on me Elliott, not now"
"We'll keep fighting Elliott, always"
Gabriel Reyes (Reaper)
"Are you kidding me, I throw everything I have at you only to die like this? What a waste of my time"
"Off to see your dad at the VIP area in the sky?"
"It's about time you joined me in death Elliott, now you'll know how I felt"
"Nice to see you again, Knight"
Rachael
"Elliott, you…I...don't know what to say about this"
"You won't be forgotten, we'll keep the story around"
Master Eon
"I should've known this day would come, I'm sorry Elliott"
Echo
"No, Elliott please! You can't die on me (Tears in eyes)"
"They are going to pay for what they did…all of them!"
"No no no no no, why now?"
Widowmaker
"This is payback for killing Reaper, Elliott"
"An assassin knows when to and when not to strike, you should've known that before"
"Now if you'll excuse me, I have bounty to collect"
"You should've known better than to face me too early, Elliott"
Skylands' Guardian
"I'm the new knight around here now"
"Shame it had to end this way Knight, kind of hoped you'd put up more of a fight"
"Skylands should've ended up not trusting you, then I would've made this place better earlier"
"You may be young, but you're predictable, you never stood a chance against me"
"Look into my eyes whilst you die Knight. Look. Into. My. Eyes"
Skylands' Guardian (After Reveal)
"This is the only way it had to end Elliott, Goodbye"
"This is what true justice is, this is what you deserve"
"You abandoned me, well here's my gift from me to you"
"You shouldn't have the quick and painless death, I want you to suffer"
"Elliott, it's about time this happened to you"
Count Moneybone
"I think I'll take that gauntlet back"
"Too bad, at least my bounty money will keep me up on security for the others"
Elliott (When playing as Kaos)
"No matter how may times you break out Kaos, we will always stop you"
"I'll always be here Kaos, I'll never let you win"
Rachael (When playing as Kaos)
"Typical, still losing like always"
"Well, well, well, that was way easier than the other battles we've had"
