What are some common visual motifs found in Batman comic panels that are absent in Spawn, and vice versa?

Batman panels frequently feature iconic imagery like the Bat-Signal, gargoyles, and the Gotham skyline. These motifs reinforce the themes of hope and the city's unique identity. Spawn panels rarely feature such symbols of hope; instead, they are filled with imagery of hell, chains, skulls, and grotesque demons. Spawn's panels often include swirling energy effects representing his necroplasmic powers, which are absent in Batman's world.
