(This wheel determines what happens to the holders (exception of Gabriel) if they merge more than one or two....they either experience dizziness or fatigue like what happened to Marinette in Kwami-Buster, physical damage like what happened to Gabriel in Evolution, or mental/emotional damage that possibly happened to Chloe from season 4-5 (from a theory I found) along with how Gabriel was consumed by madness and malice Rosie, I'll let you decide what might happen to 682, Hope and to you)

Mia - Emotional/mental damage (becomes more narrow-minded)

Angel - Physical damage

Skid - Emotional/mental damage (Demon form becomes unstable to mentally maintain)

Pump - Dizziness

Penny - Physical damage

Lucky - Fatigue 

Monika - Emotional/mental damage (sounds accurate)

Yuri - Dizziness

Natsuki - Emotional/mental damage (Would become more cold and brutish)

Sayori - Dizziness

Duckie - Emotional/mental damage

Tammy - Emotional/mental damage (would make sense, it would NOT work well with kids)

Toy Chica - Physical damage

Adalyn - Physical damage
