Hero Factory Brain Attack villain

Who was the bad guy who launched the brains to Makuhero City? Was him Black Phantom? Or Firelord? And also, was there something more planned for Von Nebula? Like making a comeback.


For the record, I too would seriously appreciate some clarification here, on the condition that such answers exist.

Simple answer to both: don’t know. I was planning to do an HF novel in which we would find out who was behind the brain attack. I was asked not to do it, I assume because there were plans in the future to answer that question in main story. As for Von Nebula, I wasn’t part of the HF story team, so I don’t know what plans they may have made.
