Kamen Riders' Crossover Forms

Crossover Forms are Rider Forms assumed by Kamen Riders that feature elements outside of the Riders' native series. Most of these forms utilize the powers of another Rider, either the protagonist's immediate predecessor or successor. In some other cases, the form is the power of a Rider who is not the immediate predecessor or successor. In one special instance, it was shown a Rider can even fuse their powers with heroes outside their own franchise. 
These forms, like Hyper Battle forms, are usually used only once or twice and are never mentioned or used in series canon again.
The real world purpose of these forms are threefold: to advertise the Legend Rider toy devices that Bandai sells annually, a special addition to the Riders power's for the Movie War films to add to the excitement for moviegoers and the forms acting as playable form change power ups for the Ganbarizing game.
