YOU CANNOT HARM ME WHILE DARK ENERGON FLOWS THROUGH MY VEINS! I AM INVINCIBLE!

-Starscream, TFP (flashback)

"I'm Death. Straight up."

-Death

Of course...

"You're not living up to the legend..."

"I do love the smell of fear." *inhales* "It's intoxicating."

"I believe we've reached the end now, you and I."

The Dark Lobo is inevitable, practically.

I am your alpha! Your omega! I am your answer to the mysteries of oblivion!

Honorable Scythe Goddard, Scythe

@A713 Oh I read Arc of a Scythe as well!

Here's another quote from Transformers (Bayverse this time)

"We were brothers once!"

"Once."

-Megatron and Optimus Prime, Transformers: The Last Knight

Also another Palpatine quote:

"The attempt on my life has left me scarred and deformed, but I assure you my resolve has never been stronger."

-Sheev Palpatine, Star Wars: Revenge of the Sith

I've died once before.

-Palpatine, The Rise of Skywalker

(I legitimately don't get why people say that the sequels are dogs***.)

^^NGL, that reminds me of old Ben Kenobi's line,

"You can't win, Darth. Strike me down and I shall become more powerful than you can possibly imagine."

Dude there are so many quotes that fit TDL cuz he's a generic/ultimate evil-type villain

"You're a colorful bunch."

-Shadow, Sonic the Hedgehog 3

(When he faces TSC and the Color Gang)

"There is nothing we can't destroy together."

-Ivo Robotnik, Sonic the Hedgehog 3

(Could have said this to TCO at some point)

Okay this one isn't something TDL might say, but the Color Gang's reaction upon seeing him would be:

"Who is that maniac?"

"Some super-douche with laser hands? I don't know!"

-Mantis and Rocket Raccoon, Guardians of the Galaxy Vol. 3
