Fran: *creates another shield*
*friendliness pellets explode upon contact*
Fran: *forms Skull Wand in hands*
Omega Flowey: Ooohhh, nice fancy skull wand. What're you gonna do, magic your way out?
Fran: No.
*Skull Wand turns into a huge staff*
Omega Flowey: Are you gonna hit me with that?
Fran: Wrong.
*blade grows out of the top of the staff making it a Death Scythe*
Omega Flowey: Ooooh so scary
Fran: *slams it on the ground*

Fran: I see you keep coming back. *raises arm* *heart butterfly appears and is now fluttering above hand*
Fran: You see this butterfly, Flowey? It's the reason I live. It may look fragile, but it is not.
*butterfly glows*
*heart butterfly turns into a black heart-shaped gem with red tinges and a few cracks*
Fran: Behold my secret weapon.
Omega Flowey: Whatever. *shoots more friendliness pellets at Fran*
Fran: *takes arm away from under the heart gem*
*heart gem rises and opens up*
*Fran points her arm at Flowey telling the gem to aim at him*
Omega Flowey: what in-
*heart gem blasts a huge beam of darkness, sorrow, evil and death full force at Flowey*
*Flowey is disintegrated*
*Fran collapses due to using too much of her power at once*
Fran: Welp, I knew the gem consumes too much power...
