Mirrorverse Tirek:

"Tyrex the Omnipotent" is a benevolent centaur entity heralded as the Great Titan of Equestria by unknown legends and sometimes considered as the most powerful being in existence. Long ago, as a mortal, he stopped his brother, Scorpan, a demonic from committing atrocious deeds upon everypony and sacrificed himself as a result of Scorpan's ultimate demise. For this, Tyrex ascended into someone greater; a god. Though this mysterious Titan is rarely seen and believed by anypony, all of Equestria feels his presence.

Tyrex prefers to keep his distance and pound his foes with magic, casting up to three spells at once (one normal, one quickened, and one hastened). He takes to the air if it seems helpful, hovering above the conflict and raining magical oblivion upon his enemies. He willingly enters melee if necessary, casting quickened spells every chance he can. He uses avatar if he exhausts his spells.

Mirrorverse Grogar:

Grogar is the fair ruler of Tambelon, a wise and intelligent prophet ram, a loyal servant and follower of the Great Titan Tyrex and royal adviser of King Sombra, leader of Equestria. As his title entails, he has been granted the gift of untold magic and prophecy, and — aided by Tyrex — has guided his people as they fled from, and later fought against, Princess Celestia who brought her own subjects in misery and humiliation under her terrible tyranny. Soon, the Prophet found himself a role in the war against the Jailer of the Damned, Emperor Icecrown, aiding Sombra and Tyrex against the vast undead empire called the Scourge.

Just to throw out an idea... what if a Mirror Tirek is always in his "puny looking" form because he is so benevolent that he gives his magic away to those in need, sort of like a living battery?
