Muscle

The Muscle rogue is one who requires equal parts cunning and raw physical power. With an emphasis as a melee combatant, you have the maneuverability of a rogue and the weapons of a fighter.

Level 3: The Right Tools

You gain proficiency with martial weapons, medium armors and shields. Also, all melee weapons have the Finesse property for you and you can ignore the Heavy rule.

Level 3: Cheap Shot

When you attack a creature with Sneak attack they have disadvantage on attacks against you until the start of your next turn.

Level 3: Mean Mug

 You gain proficiency in Intimidation, or expertise in Intimidation if you were already proficient.

 

Level 9: Dirty Fighting

As a bonus action, you can use Dirty Fighting to make a target within 5 feet of you to make a Constitution saving throw (DC 8 + proficiency bonus + DEX modifier) or become blinded until the end of your next turn. Once hit by Dirty Fighting, you may not use it against the same creature again.

Level 9: Gang Up

 When you use sneak attack, if the reason it applied is because an ally is also next to the enemy that was attacked within five feet, the ally may use their reaction to make an attack against the creature. This can only be used if the enemy has none of its allies within 5 feet of it.

Level 13: Last Word

 If you kill an enemy that has made an attack role against you,  you can regain Hit Points equal to 1D10 plus your Intimidation bonus. You may do this a number of times equal to your proficiency bonus per long rest. 

Level 17: Biggest Bully Around

When you roll initiative, The DM has to tell you which creature has the highest CR rating, if it is a tie, pick whichever one. Whenever you roll sneak attack damage against that creature, you may instead roll D8's when you roll for sneak attack damage.
