If Gamora married Spider-Man, it would create a fascinating and unique crossover between two iconic Marvel universes: the cosmic world of the Guardians of the Galaxy and the urban landscape of Spider-Man's adventures. Here's an exploration of how their union could impact their lives and the broader Marvel Universe.

### Character Dynamics

#### Gamora
Gamora, known as the "Deadliest Woman in the Galaxy," is a highly skilled assassin and warrior with a complex background. Raised by the mad titan Thanos, she eventually rebelled against him and joined the Guardians of the Galaxy. She is fiercely independent, strong-willed, and deeply loyal to her friends.

#### Spider-Man (Peter Parker)
Spider-Man, or Peter Parker, is the friendly neighborhood hero known for his intelligence, agility, and sense of responsibility. Balancing his superhero duties with his personal life has always been a central theme in his story. He is compassionate, witty, and driven by a strong moral compass.

### Relationship Dynamics
The relationship between Gamora and Spider-Man would be marked by a blend of their contrasting worlds and personalities:

1. **Complementary Strengths**: Gamora's combat skills and cosmic experience would complement Spider-Man's agility and scientific acumen. Together, they could tackle threats both on Earth and in the galaxy.
  
2. **Balancing Responsibilities**: Both characters have significant responsibilities — Gamora with the Guardians and Spider-Man with protecting New York. Their relationship would require balancing these duties, leading to potential conflicts and growth as they learn to support each other's missions.

3. **Moral and Ethical Decisions**: Peter's strong moral stance and Gamora's more pragmatic approach could lead to interesting debates and mutual influence. Peter might soften some of Gamora's harsher tendencies, while Gamora could help Peter become more decisive in critical situations.

### Impact on Their Teams
1. **Guardians of the Galaxy**: Gamora's marriage to Spider-Man could lead to more Earth-based adventures for the Guardians, integrating them more into the mainstream Marvel Universe. Spider-Man might also join the Guardians on cosmic missions, bringing his unique perspective and skills.

2. **Avengers and Other Alliances**: Their union could strengthen ties between the Guardians and Earth's heroes, creating opportunities for new team-ups and collaborations. Both teams would benefit from shared resources and knowledge.

### Potential Storylines
1. **Cosmic and Urban Adventures**: Stories could alternate between cosmic battles and street-level crime-fighting, providing a diverse range of challenges and settings.

2. **Villainous Threats**: Combined threats from both their rogue galleries, such as Thanos and the Green Goblin, could present unique challenges that require their joint effort to overcome.

3. **Personal Growth**: The relationship would allow for deep character development, exploring themes of love, sacrifice, and the blending of different worlds.
