Space Dolphin is a minor fictional character associated with Injustice: Gods Among Us, appearing as a whimsical or humorous reference rather than a major plot figure. The character is not a central combatant in the story and has no significant narrative role in the main conflict between Superman’s regime and the resistance. Instead, Space Dolphin is best understood as a background or joke character, reflecting the series’ occasional use of absurd, non-serious elements alongside its darker superhero themes.
