If the character from the series appears in your story as themselves, no matter what physical form they take, then they still receive that character's tag. Spike the Dog from EQG is still tagged as Spike the Dragon from the show, for example.

1715186 thanks :) i have one more question, if i have a character, who is originally in the show and appears in my story but not in that form as we know, should i have to tag him/her as an appeared character in the story?

That should be fine, as long as they are both part of the same narrative. Best of luck!

1712294 Yes, actually i want to write a story which has different angles. Example: The first chapter is told by a pegasus and the second one is by an unicorn so the two chapters starts at the same time but at different places and plot...there are just connections between them which will help to understand the whole story.
