Off the top of my head, I was thinking about stuff like...

A single Construct with the ability to split itself into three smaller constructs, each with its own personality. They'll probably look like teddy bears or whatever, and can temporarily transform into sassy teenagers.

A big beefy Revengeance-looking cyborg that's like, 12 feet tall, uses a giant block of metal, has a beam attack originating from its mouth, and basically goes around doing massive collateral damage wherever it goes.

A quadrupedal creature covered in thick carapaces that's probably twice the dimensions of a horse and can create hard-light cannons basically all around it, turning things into a bullet hell at max capacity.

A creepy slime thing that can perfectly shapeshift into whatever it melts down and assimilates, absorbing the memories and/or functionality of the assimilated object, while also being able to wrap itself around existing creatures or objects and extrapolating them, essentially making anything it fuses with even bigger.

A cute smol anime girl with sharp fangs. But her jaw can basically open up as wide as a crocodile's, her teeth are set up like a shark's, her bite strength is some next level bullshit, her stomach has some hammerspace shit going on, and she grows physically stronger the more 'living beings' she eats.
