pre question on kamen rider decade

hi, i've heard so much about kamen rider decade even before it actually airs. i heard a lot of the past riders in the heisei era n their villains will appear in the kamen rider decade series.. i wonder how was the storyline might be?

u see, each kamen rider series in the heisei era has it's own plot n storylines which will become doesn't make sense if all the series become combined in a story.. for example, in kamen rider faiz, human hv the possibility of becoming orphenoch, and everytime a person dead, the person will rise again. if the person has the ability to become orphenoch, then that person will turn into a orphenoch. if that person cannot turn into orphenoch, then that person will collapsed in ashes. this scenario does not happen in other series.. ppl in kabuto or blade or agito doesn't hv this kind of scenario..

another case, in kamen rider kabuto, a meteorite fall on shibuya, japan on the yr 1999, which is prior to the kuuga series, then that means from kuuga's timeline till kiva's timeline, this scenario is a true facts ady.. then how come no imagine possess a person with the memory of the meteorite incident at shibuya? surely something like that will leave a strong memory among many ppl.. right?

well, this r just some example.. what i mean is each stories hv their own different plot, therefore i was thinking how they can hv all the plotlines combined in one series in kamen rider decade? i would like to know.. well, how do u think?

If I recall correctly, it's like the different Riders are from different universes/dimensions.

They are all from different universes and Decade can travel to other universes.

i was wondering if other riders in the past will appear or not when Decade travel to their respective universe or dimension, such as G3, gills, delta, chalice, ibuki, todoroki, gattack, drake, kick hopper, zeronos, IXA n so on.. so far i've known, another agito is dead. all the riders in ryuki had died, except knight mayb or kitaoka-san, if he survived the cancer. delta's belt is destroyed by the orphenoch king in the series finale, garren's belt is gone or destroyed after he plunged into the sea with the category king after defeating it, zanki is dead, sasword is oso dead, thebee zector has no user, n den-o returning his rider pass to the Owner and zeronos has no more card left..

i wonder if those rider mentioned above will still made an appearance in the Decade series.. well, i'd sure miss to see all of them again, if possible, including those that may be appearing in 1 or 2 episode, like danki, sabaki, eiki in kamen rider hibiki..

it will sure be fun.. right?

Most Asked Q would be-
Will the original actors be back for their Kamen rider roles?
Who's the enemy?the riders?the previous enemies?
It would be fun that Decade will defeat each rider and seal their powers for his own uses.
