Next sentence: "The Flash’s origin story is a compelling one, and the show’s success can be attributed to its well-developed characters, engaging storylines, and the charismatic performance of Grant Gustin as Barry Allen."

Next paragraph:

I need to make sure each term is replaced with three suitable synonyms, keeping the original structure and names. Also, check if any terms might have been missed, like "lightning storm" becomes thunderstorm, electrical tempest, storm surge. "Coma" could be deep sleep, unconscious state, stupor.

Okay, let's see what the user is asking for. They want me to replace all the terms in the given text with three synonyms formatted as syn3, keeping the brand names untouched. The final output should be the text only, without any markdown.

Finally, "Action and Visuals."

Wait, the instruction says to keep proper nouns, but "DC Comics" is a brand name, so it stays. So proper nouns are preserved.
