Here is an idea I have been working on. I seen a few Kamen Rider Gaim crossovers where a few riders are replaced with other characters but a lot of the other riders stay. That's find but I thought it would be interesting to do a story that replaced all the riders. I couldn't think of any one series where I could replace the riders with people of slightly similar mindset. Then it hit me why do one crossover when you can do multiple.
I got a couple ideas for the replacement riders and could use some help with others. I going to try and avoid harem characters so not have to many people. I going to try and have all the riders (expect zangetsu and ryugen) be from different series. I am open to changing some of the character used for riders as long as they fit my criteria.
I going to try and post a chapter that showcases each of these characters as riders. When I do the riders preview chapter that character is going to be lockdown as the rider.
Here is what I have so far.
Gaim- Unsure need someone with morals that wants to save people. Want to avoid characters what other have chosen to be Gaim.
Baron- Kiriha Aonuma (Digimon Xros War) I need someone that covets strength but is not evil and he was the first one that came to mind.
Zangetsu and Ryugan- Shirou Emiya and Illyasviel von Eidzbern (Fate/stay Night) need a sibling pair where the older sibling was someone that would do whatever he felt was necessary for the good of all, while the younger would have no problem manipulating others.
Gridon- A teenage Minaka Hiroto(Sekirei) wanted someone smart but could be used as a but monkey.
Kurokage- Makoto Ito (School Days) since whoever became Kurokage was going to be killed off I decided to choose a character myself and a lot people do not like.
Bravo- Undecided looking for someone that is artistic and has fighting experience.
Knuckle-Undecided maybe someone that is a bit of a background character.
Duke- Lloyd Asplund (Code Geass)- Wanted a unhinged scientist that wants to improve his creations no matter what.
Sigurd- Undecided want someone who is a bit of a slime ball preferably that hate taking orders.
Marika- Undecided want a woman that would serve someone loyally and may be attracted to strong men.
