What are some common tropes or storytelling conventions found in manga that are less common in American comics?

Manga frequently utilizes tropes like the 'tsundere' (character who is initially hostile but gradually warms up), 'moe' (affection for cute characters), and power-ups through emotional breakthroughs. Recurring themes of honor, sacrifice, and perseverance are also prominent. American comics, while also having tropes, often focus more on large-scale events and interconnected universes.
