Butcher

Some rogues rely on subterfuge; they must be hushed, stealthy, and unseen. You are not this. You are a butcher; you beat down your foes with strength and pure power. You have no need for the quiet life; take existence by the horns and bring it crumbling down.

Strong Armaments

When you choose this archetype at 3rd level, you gain proficiency with flails, morningstars, war picks, and medium armor. Additionally, you may apply your Sneak Attack damage to attacks made with any simple weapons, flails, morningstars, and war picks.

Sprinting Strike

When you choose this archetype at 3rd level, you learn to inflict major wounds by charging your foes. You gain an additional way to use your Sneak Attack; you don't need advantage on the attack roll to use your Sneak Attack against a creature if you move at least 20 feet towards the target beforehand on your turn. All the other rules for Sneak Attack still apply to you.

Face Mortality

At 9th level, the mere sight of you sends shivers down the spines of your foes. When you make a successful melee weapon attack against a creature, you may make a Strength (Intimidation) check with a DC equal to 8 + the target's bonus to Wisdom (Insight). On a failure, nothing happens. On a success, the target becomes stunned until the end of your next turn. This feature has two uses, and all expended uses are regained at the end of a long rest.

Demolitionist

At 13th level, you learn to break objects apart with ease. You may apply double your base damage + your Sneak Attack damage to any attack made against an object.

Wicked Grin

At 17th level, you become capable of striking fear into the hearts of all.  You can use a bonus action on your turn to gain advantage on the next Charisma (Intimidation) check you make during the same turn.
