Question: how to unlock all characters in dragon ball z fighters?
Answer: Here's how to unlock them all: Android 21: Beat the story (consists of 3 arcs, each one has 9 chapters). Vegeta (SSGSS): Earn 300,000 Zeni across all game modes or beat Arcade's “Gravity Spaceship Course” with A-Rank on hard difficulty. You unlock hard difficulty after beating the normal version of that course.
