Bigby's titan

The long forgotten full form of bigby's famous spell "bigby's hand"
you create a 20ft tall giant made of shimmering, translucent force in an unoccupied space that you can see within range. The Titan lasts for the spell’s duration, and it moves at your command, mimicking the movements of your own Body or  you can command it from the inside although doing so would restrict your spells to self effecting only but triple the duration to 30 min Concentration

Bigby's titan has the following characteristics

An  AC 22 and hit points equal to twice your hit point maximum( If it drops to 0 hit points, the spell ends) It has a Strength of 30 (+10) and a Dexterity of 14 (+2)
The titan has 60 ft move speed which it can take when ordered 
The titan can fully utilize all the features of (bigby's hand) with more power behind it
when piloting the titan you gain its AC and Hp if it dies you die with it 

• Clenched Fist. The titan strikes one creature or object within 5 feet of it. Make a melee spell attack for the titan using your game statistics. On a hit, the target takes 6d8 force damage.

• Forceful Hand. The Titan attempts to push a creature within 5 feet of it in a direction you choose. Make a check with the Titan’s Strength contested by the Strength (Athletics) check of the target. If the target is large or smaller, you have advantage on the check. If you succeed, the hand pushes the target up to 5 feet plus a number of feet equal to five times your spellcasting ability modifier. The Titan moves with the target to remain within 5 feet of it.

• Grasping Hand. The Titan attempts to grapple a Gargantuan or smaller creature within 5 feet of it. You use the Titan’s Strength score to resolve the grapple. If the target is large or smaller, you have advantage on the check. While the Titan is grappling the target, you can use a bonus action to have the Titan crush it. When you do so, the target takes bludgeoning damage equal to 4d6 + your spellcasting ability modifier.

• Interposing Hand. The Titan interposes itself between you and a creature you choose until you give the hand a different command. The Titan moves to stay between you and the target, providing you with three quarters cover against the target. The target can’t move through the Titan’s space if its Strength score is less than or equal to the hand’s Strength score. If its Strength score is higher than the Titan’s Strength score, the target can move toward you through the hand’s space, but that space is difficult terrain for the target.
