Blast me with radioactivity until I turn to ash.

Pour Anti-freeze into my nearly headless neck from a failed clean cut with the flaming sword.

Overstuffing me with cupcakes and cookies O.o;

slit my throat with her knife

Probably inject me with something from inside that rather shady looking coat.

Headbutt me with those horns ending in a fractured skull.

She'd be all sweet and lure me into a trap where, with my guard down, she'd take all my power for her own.

drop me off a cliff while throwing blades at me while falling

Stab me with her hair sticks.

Freeze me with her icy eyes.

throw a ball of darkness that disentigrates my face

Wrap those bindings around me until I'm crushed.

Have her bird peck out my eyes and then stomp me with those heels.

push me into the Gulf of Mexico.

Beat me with her bow.

He would smack me to death with a spatula.
