The Strongest Hybrid in the Galaxy

You've found a strange alien device that gives you the powers of various alien species in one way or another. What is it? What does it do? And how will you use it? Been on a nostalia trip with Ben 10 lately, so I thought I'd make this. Make your own Omnitrix and enjoy the scenario! I will continue to edit this with more villains and aliens. Update: 🎴Auto-Cards fixed, should work now2
