Cross-Universe Plan Z (OCs x Multiverse Crossovers)
6 parts Ongoing Dr. Jennifer Robotnik has always been a brilliant mastermind. Founder of Robotnik Industries and always able to fix her older brother's mistakes, she could be seen as an even greater threat to Dr. Eggman himself. As of recently, Dr. Eggman was defeated and nowhere to be seen, thus allowing her to take the remnants of what remained of the Eggman Empire to bring it into her Robotnik Industries.
Behind the scenes, she managed to retrieve the Phantom Ruby, where she had learnt the true capabilities of such a Relic, only to discover there were actual other realities that existed outside of her own. With this, she intends on bringing forth a way to combine them all together as she wants to shape it into her own image. However, two particular Hedgehogs intend on preventing her plans as it leads to her Cross-Universe Plan Z to come into fruition, with some costs of course....
