This is a Crossover with mlp Characters as Characters from Doraemon.

I don't know who made the robot Spike I used for the Cover art but all their art looks amazing, just can't find the actual sourse

One day, as Twilight was tinkering with the portal, she accidentally sends herself and her friends to another world. And they’re no longer ponies, but wolves. They have to learn and adapt to their new bodies and instincts until they find their way home. Along the way, they'll make new friends and face new enemies. But maybe they’ll see that being a wolf isn’t that bad.

When everyone else turns out to be too busy to do it, Spike volunteers to babysit Princess Flurry Heart for the day. He does his job all right for the most part, but things begin to shake up a bit when Sweetie Belle stops by and insists she help Spike take care of the baby. After some hesitation, Spike relents and decides to let Sweetie Belle help him. The day goes on and Spike and Sweetie Belle babysit Flurry Heart together, almost like their own little family.

A Displaced Rider Story.
I'm putting this Rated Teen mostly cause I'm not sure completely what else I'm putting in besides the language a bit so far.

All Kamen Rider and Equestria Girls belong to their original owners.

After a conversation with the Mane Six causes Spike's mind to wander and fill with worries, he tries to find a quiet spot to collect his thoughts and think things thru. However, during his "free time", he finds himself in the magic mirror room again. As he watches himself, he makes a simple, silly mistake that ends up sending him back to that strange, pony-less world. This time, he doesn't have Twilight's help, but the strangest thing is the way he appears there: much less dog-like and much more...human.

(This story is located in a "flexible" timeline, the only events that occurred in the human world were the ones of the first movie.)
