I'm so sorry it took me this long, but I finally drew Grogar!
I love his G4 design and how faithful it is to the old G1 cartoon version and I'm really excited to see where they take this villain in the finale! I'm still wondering how he's going to outsmart Twilight and the others and how they will defeat him but I am sure I'll be surprised nonetheless! But let's all be honest, the REAL final villain will be that painful, hot lump in our throats once the credits roll for the final episode!
Well anyways, there's Grogar and this will most likely be the design I'll be using for a pinback button in the future when I sell at another convention.
