Make sure that the audience knows your protagonist is super special despite being just a regular guy, and has some vague tragic background that justifies any shitty behavior. This background is also essential for creating an underdog protagonist, even though he has an untapped well of power stronger than basically anyone. Because he is so strong, don't bother making him smart or anything because he can just power through with brute force. Actually, clever battle tactics are a huge waste of time since nobody really pays attention. Only total losers use any sort of foresight or strategy. Plot armor is your friend.
If you accidentally create likeable characters that have overcome genuine obstacles and changed their behavior, that won't be a problem. Just relegate them to the background cast and make sure they only show up now and again to remind the audience that they exist. ALWAYS REMEMBER: Even if they are a villain turned good they should NEVER apologize or reflect on their past actions. That was the PAST and they are GOOD now.
Speaking of villains, don't give them any motives or reasoning besides, like, being evil. Diving into a major character's backstory or perspective is a massive waste of time and will confuse your audience too much, so just make them extremely evil/homoerotic and call it a day. They probably just need a good talking-to and an epic smackdown to become a good guy after all.
Women are very important to a story - they have tits and ass, after all. Thus, giving them a real personality would only detract from the true appeal of the character, actually try to give them the most repulsive personality as possible. There are three tried and true options: give them the opinions and independence of a five year old who depends on a man constantly, give them the outfit and attitude of a hard leather dominatrix that enjoys seeing men in extreme pain, or make them a selfish bitch who gets into catfights over some guy. Every other character should be completely ok with this; they are women, after all. Your male audience will completely love this, and any women who say otherwise are just jealous they aren't as hot as your fictional waifus.
In short, men strong, women hot, villains bad. Do NOT deviate from this if you want anyone to like your work, EVER.
