(This is my original character with fusion of Frisk and Chara)

While Kid Buu fighting Frisk and Chara but Kid Buu was too strong for them so they have no choice but wear Potara earrings to fusion, Frisk and Chara wear Potara and they fusion into Friskara she then use her all power on Kid Buu, after 1 hour fight, Kid Buu just fly away, she just smirk at Kid Buu, her hair was longer, she has purple eyes (blue + red), her face was look like Chara's, has Frisk's clothes, her pants was a brown like Chara's but longer and she tall 5'3

Friskara: This is the fusion between Frisk and Chara, this is... Friskara, i also know as 'The Strongest Little Girl'.

There is Frisk's and Chara's voice at the same time, and of course, there is a Potara Earrings in her ears, Friskara is also a Supreme Kai of Time (former but later retired because of responsibilities)
