Ok. So...as you know, a few years back, The Guardians accidentally betrayed The Sovereign when Rocket stole some of their batteries (by the way, didn't know Guardians 2 took place a couple months after the events of Guardians 1) and ended up on The Sovereign's shit list. After failing to stop the Guardians...TWICE!, their relentless leader, Ayesha, created a being named Adam Warlock that could be capable of destroying the Guardians. Now, as Yondu said, nobody would be stupid enough to try and take on the Guardians of the Galaxy, as they are a bit of a representative to the Nova Corps and anyone who would try would end up with the Novas on their asses. However, since Thanos mercilessly wiped out the entire Nova Corps when he got the Power Stone and decimated Xandar, or half of its population, everyone that the Guardians ever pissed off, including the Sovereign, will be on their asses without The Nova Corps to protect them. And you can bet the Sovereign will use their new weapon to try and take them down. But what do you think? Do the Guardians have a chance of defeating the Sovereign, who are backed by Adam, or not?
