Way of the Dynamo

Might, My Armor

At 3rd level, you've trained to thread minuscule portions of your ki throughout your body, creating a defensive weave. While you are wearing no armor and not wielding a shield, your AC equals 10 + your Constitution modifier + your Dexterity or Wisdom modifier (your choice).

Power, My Weapon

Also at 3rd level, you bring full force to every battle, and will not relent. When you make an unarmed strike with a bonus action, you choose one of the following benefits:   If you hit a creature that is prone, you score a critical hit unless the creature succeeds a Dexterity saving throw.   If you attack a creature that you are grappling, the attack is made at advantage.

Determination, My Shield

When you reach 6th level, you do not fear attack, but meet it with a resolve as sharp as steel. When you are hit by a melee weapon attack, you can use your reaction to turn the strike into an opportunity. When you do so, the damage you take from the attack is reduced by an amount equal to your Strength modifier (minimum 1) plus the result of rolling the martial arts die indicated for your level.   If you reduce the damage to 0, you can spend 1 ki point to catch the attacking creature's weapon in a trapping maneuver. Their attack misses and they are considered grappled by you. This special form of grapple can end early if the creature drops their weapon. Until the grapple ends, the creature can't attack with the trapped weapon.

Resolve, My Wings

At 11th level you learn how to unleash a devastating kicks while airborne. Once a turn when you make a long jump, your next midair unarmed strike pushes the target away from you half the remainder of the distance of the jump on a hit. You can choose to travel with the creature for that distance, or rebound off in a direction that you choose for the same distance.

Strength, Their Ruin

At 17th level you can spend one ki point (no action required) to empower all your unarmed strikes until the end of your turn. Until the end of your turn, any time you hit a creature with an unarmed strike you can attempt to grapple or shove them as part of the attack.
