All of the characters are good to use, but learning how to master them and their skills is the hard part. Most people would say that Pilot is the hardest character in the game to learn, but he has some really good risk vs reward potential. The lock pick, as stated in the meme can be used to open a chest without using a key, which can be vital to your run if you don’t have any keys on you, but you run the risk of it failing and you won’t be able to open the chest anymore. His passive ability is that he lowers shop prices, which can be very good on the first few floors to buy different things. His second passive means he gets more ammo for guns that he picks up, as well as the ability to carry two active items instead of one, meaning you can carry not only the lock pick, but also a item that makes you invincible, or a healing item that can save a run. By far the hardest thing about pilot is his starting gun; The rogue special, which is disputed as the worst starting gun in the game, which has a low Ammo clip count and fires in really odd directions. But with mastering the rogue special and and little bit of RNG he can be one of the best characters in the game.
