In the original Power Rangers story, the main villain was Rita Repulsa. She was an evil space witch who was imprisoned on the moon but managed to send her minions to Earth to cause trouble.
The villains in the Power Rangers Original Story often come from other dimensions or planets. They are usually power - hungry and want to conquer Earth for its resources or just for the sake of ruling over it.
In a crossover with the Marvel universe, Thanos could be a formidable villain. His desire to collect the Infinity Stones and his power would pose a huge threat to the Power Rangers SPD. The Rangers would have to team up with the Avengers to stand a chance against him.
Well, it's somewhat popular. Some fans are really into this concept because it's different from the usual Power Rangers story. It gives writers a chance to be creative and show relationships that are not in the mainstream shows. However, not all fans like it as it goes against the typical hero - vs - villain setup that Power Rangers is known for.
I found two novels that fit the requirements. The first book was " Mechanical Godzilla: Born to be a Great Villain." The main character was a mechanical Godzilla who was an enemy of humans. The novel was full of fierce battles and thrilling plots. The second book was called " The Adorable Villain Is Not Human [Quick Wear]", which told the story of a protagonist who traveled through time and space to become an Adorable Villain. These two novels met the requirements of villains not humans.
One idea could be a story where a new ranger has to hide their identity as a ranger from their family who are against any form of superhero activity. It adds a layer of drama and secrecy.
Tommy is another fan - favorite. You could write about his journey from being an enemy to becoming a powerful ally. In fanfiction, you can expand on his internal struggles during this transformation and how he impacts the team dynamic.
One common storyline is the monster who has a change of heart and falls in love with a human Ranger. They then have to hide their relationship from both the Ranger's team and the monster's kind. Another is a human Ranger who is captured by a monster but instead of harming them, they develop feelings for each other over time.
The determination of whether the Power Rangers comics are canon isn't straightforward. It often involves factors like consistency with the TV show, official statements from the franchise, and fan consensus. Different fans might have different opinions on what constitutes canon in this case.
