That clown Imagin does comes from Den-O as you says KyoryuGreen. The clown comes from the first heisei team-up called Kamen Rider Den-O & Kiva: Climax Deka.

As I can say for now, from now on there will be no hints unless you want one. (But there will always be one for each monster at the super sentai version)

Note: 10th monster

I don't know why anyone wouldn't recognize Aries. Fourze

I think it is because the most members of tokunation are living in america and now it is nighttime I think... but whatever so yeah OathToOblivion that monster is from Fourze. You are the winner.

This one are gonna be a hard one:)
