At the start of the game, when making your character, if you name him with a few commas, he will start with extremely boosted stats and armor. You can also randomize him to the stats and armor that you'd like. But be warned- the more commas you use, the stronger he gets, but also the more likely your game will crash to the title screen. You ideally want to use 3 commas.
