This is what would happen if Lulu and Jesabelle were to make contact while Jesabelle is in her latex form, as for Lulu, being based off of Changed, she is always in a latex form.

If said contact was to happen in said forms, the 2 would end up combining, creating a hive mind being, but, unfortunately, neither of them could handle it and the combination would essentially leave both of them braindead, permanently. It would practically kill them.

Luckily, the hive mind hasn't happened to the original ones, but 2 multiverses have shown the hive mind's creation, leading to research on it and it's very discovery. One discovered as dormant and stationary in [UNIDENTIFIED] and one showing movement in [UNIDENTIFIED].
• Note that both worlds are considered unidentified, as major research in the worlds are still ongoing.

Let us make sure the living costume (Jesabelle) and the latex creature (Lulu) never lose their lives to such a mistake.
