Linkspike (Link!Spike), Twizelda (Zelda!Twilight), and finally Ganonbra (Ganondorf!Sombra) appears!

Sombra is here to steal waifus, especially Spike's woman, Twilight Sparkle.

Ganonbra : MINE! SHE'S THE CRYSTAL!
Linkspike : Screw off, I found her first!
Twizelda : I... don't know how to deal with these men in a state like this... Handsome boys all over me... :P

Twilight Princess? Twilight Princess.
And the Hero of time who is a dragon.
Also Dark lord Sombra is now dark lord.

Spike is courageous when needed.
Twilight Sparkle is a high wisdom princess.
While King Sombra is obsessed with power.

Cosplay uniform based on Hyrule Warriors.
Note: Twilight is far from a damsel, while Spike is more of it, due to target audience of MLP differs from LGZ, but personality-wise, Spike is close to Link (chick magnet harem boy) and Twilight is close to Zelda (magical smart princess).
Ganondorf and Sombra are often compared to each other, so it makes sense here as well, although Ganondorf is a bit more competent in his villainy than Sombra.
