Fennel Seed Ranger or the idea can burn... on the stove.

What if they did a Gridman/Tron idea? Where all the fights take place in the Internets.

Could even do a whole Ace Lightning thing and have the video game break out into the real world. Make the Lightning Knights the Rangers.

I had an idea for a Super Sentai/Power Rangers season where the Rangers transported the monsters into different "Zones" and fought them there.

This idea also involved the Super Sentai season to be a prequel for the Power Rangers season. Oh, and the Rangers got their powers from Core Medals that the Kougami Foundation cooked up and gave to them to fight the Greeed he accidentally created.

My idea for a medieval knights theme is that all of the knights are based on European legendary creatures. For example:

1. Red (male) - European dragon
2. Blue (male) - Sea Snake
3. Yellow (female) - Gryphon
4. Pink - Fairy
5. Green (male) - Goblin
6. Black (male) - Hellhound or Zombie
7. White (female) - Unicorn
8. Gold (male) - Phoneix

The 6th ranger should be evil and won't turn good. If they go for a undead theme for him then he can summon and control the dead around him.

This needs to happen :lol

So many good ideas here. Yet dinosaurs, cars and myth stuff are the most popular. We really need more variety in Sentai.

Remember my old idea to go with Gaim? すくすく戦隊ベジレンジャー/Sukusuku Sentai Bejiranger/Quick and Healthy Sentai Veggie Ranger

:lol

Here, let me develop that idea further:

*Every Ranger would have three types of Core Medal, each corresponding with a different Greeed.
*A Morpher can be used without Medals to access the blank Default Form; one Medal unlocks a Super Form (the base form); two Medals of the same type unlocks a Hyper Form; three Medals of the same type unlocks a Maximum Form; two Medals of different types unlocks a Duo Form; three Medals of a different types unlocks a Trinity Form.
*The first Megazord (which I have named MedalOh/King Medalos) is composed of a blue bat, a red buffalo, a green wolf, a yellow frog, and a pink shark.
*The Blue Ranger is the leader, because it's about time.
*The Red Ranger is female.
*The Sixth and Seventh Rangers are Black and White, and play off of an opposites motif (e.g. their initial Zords are a dog and a cat).
*The Yellow Ranger is constantly screwed over in the theme department.
*The Green Ranger is unintentionally the most school-spirited in terms of his motif.
*The Pink Ranger is only bemused with the pink shark thing.
*The colors might be adjusted to better accommodate a possible visible-spectrum motif.

First, as far as the cowboy mecha option, its a stage coach pulled by 4 animals, with the coach itself is the red ranger's. The other 4 rangers can split off, which leaves the stage coach to turn into a stationary bunker/giant turret cannon thing (a maneuver called the Rodeo Roundup).

Two, I've always wanted a sentai series where the rangers were like gorilla fighters, using hit and run tactics to slowly weaken the massive evil empire. At the beginning of the season, they'd show all the MOTW at once, and the rangers would pick and choose when and where to fight them, and only on their terms. Now, this would almost never go quite as planned, but still. It would be kinda how I imagine the gokaigers operated prior to the show.
