Firstly refrain from reviving topics several months old. Brendan had a appearance at the beginning of that movie not Red.
One thing you may want to consider is the Manga and Anime are oriented to different groups. In the manga it seems to depict more mature themes, as well as there is not really fillers it sticks to the points and is more driver whereas the Anime is all over the place.
That being said the question of the topic is Red in the Anime and the resounding answer is that he is depicted through a counterpart in Ash. So there would have it, if someone wants to make a new topic on this then fine, but we will leave this one as it is.
