Due to the use of late game topics, spoilers as follows.

I want to see how quickly I can kill the Doctor, and I want to get enough missiles to destroy both forms of him. Through the game, I came across enough missile max upgrades to get it to 25 (only got 20, skipped the zombie sky dragon one). Are there any other ones I can collect, and if so, where are they?

There are 5 missile expansions that bring you up to a grand total of 54 missiles. The first 4 on this list give you 5 missiles each, while the last "Bonus" upgrade gives you an additional 24.
