Magus Agrippa

He was simply a normal biologist that studied the magical creatures of his world before he fell into a portal and ended up in another Earth. This one, where things work a little bit differently than the Earth he's familiar with. Downside is, his body shattered when he arrived, and he had to latch his soul onto someone similar to him- his 'Earth Two' counterpart, Dottie Agrippa. Over two years later, not only was Magus able to build a body out of the right kind of material to prevent problems with being from Earth One, but yet another portal accident led to him and Dottie fusing together with an extra helping of the Void Juice he had been studying, resulting in a shared body with incredible eldritch potential. Magus maintains his abilities as a master of arcane forces, using his grimoire to channel elemental magics and telekinetic feats, while Dottie boasts further enhanced strength and a magic hammer that can smash through pretty much anything if she swings it hard enough. Magus is also the creator of a race of Slimes known as 'Jeremy', who are pretty cool dudes that possess different abilities based on their diets. It is said that if enough Jeremy come together, they will merge and ascend into a Presidential Jeremy, who you have already voted for. You just don't know it yet.
