There are 240 Combo Challenges in Dragon Ball FighterZ. For trophy / achievement "Before Creation Comes Destruction..." you need to do 200 of them.

Each character has 10 combo challenges. There are 21 characters unlocked from the start and 3 can be unlocked through game progression, making it 24 characters total. Thus you have 240 challenges to choose from and can skip all of the difficult ones.

The first 8 are always very easy. The 9th and 10th get more tricky. If you do 9 challenges with each character you'll get the trophy in no time.
