He sit

So cracking Maulbuster is one of the worst things ever

What is cracking and Maulbuster is the tomato volleyball, right?

Maulbuster is the theatre girl who loses her shit and throws the tomato at you
Cracking is doing it in one run without taking damage and without using checkpoints

Ohhh

"MAULBUSTER is the Matriarch of the Bossbuster Brigade. A cultured, classically trained actor whose mind is a steel trap, she keeps the entire Ballbuster Army in check. Her only problem is her complicated and to-the-letter plans sometimes go awry, so when Anton and Annie refuse to follow the script, she just might get caught flubbing her lines. Eh, they're all in Mole language anyways."
her official description

that is one masculine female

She's actually a bit more feminine if you look closely
She has eyelashes and long hair

I think I only saw the bird wing eyebrows and thought it was a guy
But yeah makes sense
anyway yeah she looks hard to beat

She isn't hard to beat at all
Arguably one of the easiest bosses
It gets hard when you try to beat her without taking damage

Oh

Right, because of the HP system
