Based on the information available, there isn’t a clearly defined, real-world lineage or canon of “generations” explicitly joining a fight against a Vanderberg Corporation in widely recognized sources. If this refers to a fictional storyline (for example, related to the Now You See Me film franchise or a contemporaneous marketing/alternate-reality narrative), details about how many generations participate can vary by media, edition, or promotional material. Here are a few ways to get a precise answer quickly:

• If this is from a specific movie, show, or marketing campaign, share the exact title, release year, or a link to the material. Then I can pinpoint the number of generations depicted as joining the fight.
• If you’re looking at a fan-fiction or a non-canonical adaptation, indicate that context and I can summarize what that version states.
• If you want, I can search for the latest official materials or reliable summaries to confirm the number of generations across different sources.

If you can provide more context (the exact work or medium, and any relevant quotes or scenes), I’ll tailor the answer to that source and give a precise count with citations.
