Season 1 follows siblings Taylor and Hayley as they set out with their very own Jaeger to try to find their parents, who left them years ago on a mission to try to rid the world of kaiju. They never came back, and while the teens don't find their parents by the season's end, they come across some more information in terms of what happened to them. The duo discovers that their parents abandoned their Jaeger years ago and likely made their way to Sydney, Australia, so that's where they're going to continue heading for season 2.
There are bound to be some roadblocks up ahead. Shane very clearly wants those kids dead, and now that Mei has betrayed him after he treated her like a daughter for so many years, he's likely out for blood. There's also the mysterious hooded figures who are after Boy a.k.a. the Kaiju Messiah. We'll likely learn more about what their deal is and what exactly they want to do with Boy, but it's probably not going to be good. And naturally, they're still on a continent filled with monsters, so expect more than a few larger-than-life battles going into season 2. The real question is whether we'll get a chance to see more than just a couple of new Jaegers join in on the fight.
At the end of the day, we can be relatively certain that Pacific Rim: The Black season 2 will have plenty of punching, gunfire, and mysterious powers. And really, what more can you ask for from a show?
