Sequel to Spiders and Loyalty: Maximum Shadows. And a semi-sequel to The Miraculous Spider-Tsundere: Miraculous Generations

I'm changing the name from Deadly Vengeance to Deadly Alliance.

Spider-Tsundere goes to Equestria to be honored by the 4 princesses for saving their home from the Nightmare Pony of Shadows. Only to later on, return again to investigate the disappearance of a rouges gallery not being anywhere in Neo-Tech City, Paris or even the rest of the world.

meanwhile, Black Fox and Mysterious have teamed up with Tirek, Chrysalis and Cozy Glow and have formed their alliance to take down Spider-Tsundere if she ever returned to Equestria, Twilight Sparkle and her friends once and for all.

Spider-Tsundere, Twilight Sparkle, Rainbow Dash and the rest of their friends will be facing their biggest challenge as they face the scorns of their past, and save both Earth and Equestria... from The Deadly Alliance
