Alpha Titan: Mechagodzilla

Infinite energy. Unlike natural titans, Mechagodzilla is charged directly from the source, and has unlimited stored energy. However the cybernetic implants need to charge up, before they can release a more powerful attack.

Mechatitan. Mechagodzilla is immune to the commands of any alpha titan.

Metal Body. Any damage Mechagodzilla receives is reduced by 30.

Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.

Flying. For Mechagodzilla to fly, it needs one round to charge up its thrusters before taking off.

Massive Build. Mechagodzillas attacks count as magical in order to ignore resistances.

Multiattack. Mechagodzilla makes two claw attacks, a tail attack and two rocket barrage. It can replace any and as many attacks with charge actions if it wishes.

Claw Attack. Melee Attack: +15 to hit, reach 30 ft., 1 target. Hit: 45 (3d10 + 20) [bludgeoning] damage and *rounds charging*x10 force damage.

Tail Attack. Melee Attack: +17 to hit, reach 100ft., 1 target. Hit: 50 (4d10+20) [piercing] damage.

Proton Attack (recharge 5 6). Ranged Attack: targets in a 20x900 feet line musst make a dc 25 dexterity save or take (5d10 + 50 + *roundscharged*x5d10 + *rounds charged*x10) [force] damage.

Rocket Barrage. Ranged Attack: Mechagodzilla fires three rockets 600 feet with a blast radius of 60 feet. Any creatures in the radius musst make dexterity save or take 22 (2d10+10) [fire] damage or half as much on a fail.

Charge. Charges any one of its attacks.

Charge. Charges any one of its attacks.

Evading Thrusters. The incoming attack gets disadvantage, and if that attack misses, Mechagodzilla can make a claw attack on.

Beamlock. If Mechagodzilla is targeted by a line aoe attack, he can make a breath attack to counter it, but he cannot make a dex or Con save to evade it. Instead Mechagodzilla subtracts the amount of damage received with the damage of Mechagodzillas Protonbeam. If the outcome is negative, the excessive damage is transferred to the attacker. 

Mechagodzilla can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Mechagodzilla regains spent legendary actions at the start of its turn.

 Charge (uses 1 action). Charges any one of its attacks.

Rocket Barrage (uses 2 actions). Uses Rocket Barrage.
