Tarrasque

An iconic and powerful creature the Tarrasque, a 50 ft kaiju like monstrous lizard able to reflect magic and tear through buildings.
Took some inspiration from the iconic Aarakocra with a plus one bow meme and added a wizard casting fireball for good measure.
Used the 2e Tarrasque and the 1998 Godzilla as some base reference.
I like the idea that the Tarrasque is just a neutral creature and built the scene around it attacking those who have fired at it first after they stumbled into this city.
