What if Tommy Oliver didn't join the Power Rangers?

What if Tommy never joined his fellow Rangers at the end of Green with Evil Part 5? How would the rest of the series play out then? Rest assured, people, he WILL still join the team during this story, just not at the start… Think of it like this, in this story, Tommy will be going on a personal mission to repent for his sins, though what he did under Rita's spell was NOT his fault.
