I am not a legal expert, but I can provide some general information regarding copyright and potential infringement. Copyright laws vary by country, so it's important to consult the specific laws in your jurisdiction or seek legal advice for a precise answer. Whether the use of the PVZ-inspired avatar by a virtual streamer constitutes copyright infringement depends on several factors, including the specific details of the use, the jurisdiction in which it occurs, and whether any permissions or licenses have been obtained from the copyright owner.
