A True American... Kaiju?

I originally made this post for Independence Day, but I decided against posting it then. I'm not the patriotic sort in the best of times, but definitely not at the moment. 

That doesn't mean I can't appreciate the occasional stupid patriotic thing. Though to be fair, there's no way this character wasn't created as a parody/critique. American Kaiju, yes that's his real codename, is an actual Marvel character. While I don't have his technical debut, I do have have first full issue appearance.

Actions

Mutliattack: American Kaiju can use his Frightful Presence. He then makes four attacks: one with his bite, two with his claws, and one with his tail.

Bite: Melee Weapon Attack. +18 to hit, reach 10 ft, one target, Hit: 36 (4d12+10) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and American Kaiju can't bite another target.

Claw: Melee Weapon Attack. +18 to hit, reach 15 ft, one target, Hit: 28 (4d8+10) slashing damage.

Tail: Melee Weapon Attack. +18 to hit, reach 20 ft, one target, Hit: 24 (4d6+10) bludgeoning damage. If the target is a creature, it must succeed a DC 20 Strength saving throw or be knocked prone.

Frightful Presence: Each creature of American Kaiju's choice within 120 feet of it and aware of it must succeed a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeated the saving throw at the end of each of it turns, with disadvantage if American Kaiju is within line of sight, ending the effect on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to American Kaiju's frightful presence for the next 24  hours.

Swallow: American Kaiju makes one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target takes the bite’s damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside American Kaiju, and it takes 56 (16d6) acid damage at the start of each of American Kaiju’s turns.

If American Kaiju takes 60 damage or more on a single turn from a creature inside it, American Kaiju must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of American Kaiju. If American Kaiju dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.

Legendary Actions

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

Attack: American Kaiju makes one claw attack or tail attack.

Move: American Kaiju moves up to half of his speed.

Chomp (Costs 2 Actions). American Kaiju makes one bite attack or uses its Swallow.

Background

Todd Ziller was a corporal in the US army and the subject of Project: Troubleshooter, an attempt to recreate Dr. Erskine's Super-Soldier Serum. Because the formula was mostly lost, the scientists took a kitchen sink approach and filled in the gaps with Gamma enhancements, Pym Particles, Mutant Growth Hormone, and the Connors Formula. This turned the loyal soldier into a giant Godzilla-like reptile. Given the code name American Kaiju, Ziller is now a patriotic force of destruction. He's used sparingly because of the all of the collateral damage he tends to cause.
