A frequent theme is the struggle for equality. Omegas often face discrimination in omega verse settings, and many fanfics revolve around their fight for equal rights. Also, the theme of self - discovery is common. Omegas may discover their own strength and uniqueness in a world that tries to define them in a certain way. In addition, family and pack dynamics are also explored in some omega verse fanfics.
Sure. 'A/B/O University' is a great one. It has an interesting plot where an omega tries to fit into the university life full of alphas and betas. Another is 'Omega's Hidden Power' which focuses on an omega discovering his special abilities in a world dominated by alphas.
Sure is. The Spider-Verse movie builds upon the rich world and characters established in the comic, but also adds its own creative twists and modern touches to appeal to a wide audience.
