Part of my MLP/DC Comics Universe:

Grogar have been preparing his master plan for centuries, recruiting all the old threats of the ponykind in order to conquer the ponies once and for all.

But when new allies shows up, he realizes the new heroes are too powerful for his Legion of Doom. The Era of Harmony is no more, now it is time of the Metaponies.

As the rest of my DC-Universe, this is edited by rich-online. Once again thank you for your support.
