The Mane 6 confront the Legion of Doom, who have all fused into a gigantic monster.

HOOOOOO BOY was this one a doozy. This is first image in a long time that actually took me multiple days and countless hours to finish. But either way it's finished. And I'd the say the results speak for themselves.

I recently rewatched The Ending of the End, and I got kind of inspired to slightly rework my original idea for it. Originally, I had it where Grogar tricked the other villains into getting his bell for him before betraying them to his newly created army of monsters, forcing them to form a truce with the Mane 6 in order to stop him, but I liked this even more when I thought of it. Especially when the old idea would have redeemed too many villains at that point. This time, all of them (Including Sombra and Storm King) are involved, with Grogar at the helm.

This moment is actually based on the scene when the Mane 6 return to Canterlot to face the Legion of Doom on a large meadow near the city, in an attempt to snag the bell from them. Their plan once again fails, but this time, the villains come together and use the bell to fuse into a gigantic beast to crush the guardians of harmony once and for all:

The head of Grogar.
The eyes and mane of King Sombra.
The horns and arms of Tirek.
The body, fur, and tail of Storm King.
The hooves of Chrysalis.
And the wings of Cozy Glow.

I just thought this was so much cooler than just having Grogar, and would involve more of the villains.
