How to be a successful Ace Attorney Prosecutor:

Step 1) Pass the Bar exam. This is presumably very easy, considering how young some of the lawyers and prosecutors are in the series. They hand those badges out like hotcakes. Presumably it’s part of Themis Legal Academy’s graduation package, so you might not even have to TAKE the bar exam!
Step 2) Only take murder cases. This will probably happen to you regardless of whether you want it to or not, so I’m including it in the list so you feel like you have SOME control over your life.
Step 3) Be an honest and morally good person who seeks for truth and justice above all else in court. This one isn’t TECHNICALLY mandatory, but eventually you’ll end up facing off against someone from the Wright Anything Agency and once they’re involved you’d better get on the level fast, or you risk either humiliation or being arrested for murder. Better to get this one out of the way sooner rather than later.
Step 4) Pay the Detectives. Please. Gumshoe desperately needs a raise. If you aren’t going to pay your Detectives, you should at LEAST take a summer sabbatical in Europe. Germany would be best.
Step 5) This is very important: Be a sadist. Just a bit. Be a troll. A gremlin. A deranged little maniac. You’re going to be watching a lot of people suffer on the witness stand (and behind the Defense’s bench), and if you don’t enjoy watching that happen then you’re in for a very miserable career. Might as well get SOME entertainment out of it. Trust me, if you aren’t capable of making Phoenix Wright recoil in fear, you’re doing your job wrong.
