Hey! I'm seeking some clarification on the character partner section of the FAQ. What happens if a character has a different personality?

I don't know your series familiarity, but it would be something like Bakura and Dark Bakura from Yu-Gi-Oh!, where the darker half is an amalgamation of the big bad and normal character opposed to the much friendlier Yugi and Dark Yugi option that are two different people. (card games be like oprah giving out evil alter egos left and right)

I'm probably answering my own question, but I assume this wouldn't be allowed since they could be applied separately.
