My little pony: Friendship is magical.

Official translation of the mainland: Little Polly (CCTV 14 is playing ... Chinese mainland dubbing)

Official translation of Taiwan Province Province: Rainbow Pony (Youku can see the Chinese dubbing in Taiwan Province Province)

My pony: Friendship is magical.

First of all, I'd like to add that downstairs, Equestria_CN has external subtitles to download (Baidu is easy to find, please see below).

In addition, before the CCTV broadcast, Youku was originally dubbed in Chinese in Taiwan Province Province. When the CCTV broadcast, Youku's film sources were all harmonious. Now you can see what has been broadcast on the CNTV website, and there are some deletions (Chinese mainland Chinese dubbing has no subtitles, and Music English has subtitles).

Letv children's website also has Chinese dubbing (note that it is not Letv). Neither season has been deleted. Please note that there is a "Chinese \EN" button under the player, which can only be switched to Chinese after being pressed. The first two episodes are free, and members are needed later. Sometimes it may be selected as animation to watch for free every week, and the complete works will be watched for free when you have time.

And then, yeah, who has the most resources,

Pony can download HD version, with built-in English subtitles (built-in, non-embedded) and official comics. Note that this is an English webpage (Baidu searches for the following keywords).

Yay Ponies-Archive (design from Bronya)

Or, according to your requirements, this may be a better choice:

Iqiyi has the first season of English Chinese characters (key word "Pony Polly")

Popular. There are English Chinese characters in the first and second seasons of com (the key word is "my pony", but not "rainbow pony").

The source of Youku film of English Chinese characters in the third season should not be unified, because the official translation of the third season has not yet come out. This can be found in Equestria_CN (Baidu can easily find+1).

! Extra:

The MLP theatrical version was released in June this year: "My Little Pony: Equestrian Girl" has no official translation, but both Taiwan Province Province and Chinese mainland have translated subtitles (traditional and simplified, respectively, Equestrian _ CN translation).

Open the homepage of Equestria_CN, and you will see a counting board, which is the countdown to the fourth season premiere of MLP (there is still one month left). After the broadcast, Equestria_CN will begin to translate:)

If you have any questions, please ask them:)
