The poster on facebook is running the above type of campaign, and wanted some ideas on how to include Kaiju (giant monsters like Godzilla) in the campaign and how characters could best be empowered to deal with Kaiju. I didn't answer the question per-se, but came up with a plot seed that I thought might be of some use to some so I'm sharing it. Due to time constraints I'm just going to copy/paste my responses for now...have fun! Nuke them while they are in the undersea caves and most vulnerable...but be warned, sometimes there are unintended consequences. Just look what happened with the White Rose Yakuza op to take out Rodan that happened off the Coast of Fukushima on 2011/03/11...you can never be too careful. Consult with nuclear and geological experts first, and not just the local hacks down at Chozan University!! Always!!!! Worst is Rodan got away too...and now the [whatever organization the characters secretly work for] is going to have to do the job themselv...
