Franchise-Driven Retitling

Sometimes people come up with a name that is perfectly reasonable for a work but is not reasonable for a franchise and with a new franchise being built, they have to go back and rename the work for all future promotional materials.

This can often come about because the title of the first work depends heavily on an element in that work but not in the others. Possibly, the executives have chosen a theme to market and name the series (such as the lead character's name) and the early installment is the odd man out.

Naturally this can be happening when you have a first work that nobody was sure was going to be popular and so they didn't think of a franchise when naming it. It can also happen during an adaptation process — book series often also only pick up a series name much further down the line, often unofficially, and often don't bother with this process. When they come to being adapted to another medium, somebody will have plans for a franchise but not a name.
