I will hunt dragons like everyone else was. Being capable of flight, highly durable and able to breathe fire (or a similar hazard, depending on species) they weill function as excellent training for my fleets.
Me, I'm getting some practice and I shall only use Negated Superman* in my fight against them. If I can't take them down wth just that, I need more practice. Some dragon parts, when fresh, also seem to have properties which could be used to fight the cloud-beast.
Hate to say it though, but the cloud beast managed to undergo a cellular mitosis-like process. The first is the size of a small galaxy, while the second has a radius equal to that of the distance between the cores of the sun and Mars. The second could not be managed by the CloudSlayer, especially in it's drained state (hey, it has been in intergalactic space for a while) and is currently heading towards the Milky Way. It can only travel at sub-light speeds, but some items which float through this part of space have bases on them, whether they are mine or someone else's.
The concern is if it either attacks a ship entering hyperspace without shields and possessing certain types of hyperdrives or it finds a wormhole, though it is unlikely, leading to a closer part of the universe. I've tracked it's trajectory and it seems to be heading towards Celadon. Three fleets are moving to Celadon, the first shall arrive tomorrow. However, I've been tracking wormholes and there seems to be a field in it's path. These will pull it into pieces, but move it throughout space and time. One of them will bring it within 10 lightyears of Celadon.
Luckily, it will be far smaller and may even starve to death before arrival, unless it acquires energy along the way, such as from my bases there. Luckily, they have their own energy supplies, but this will prevent them from fighting off ships from enemies trying to attack planets along the superspace route (an area of space outside solar systems composed of flowing spacetime, allowing travel even faster than in hyperspace, but only in select areas and one way) this one will also allow fast travel to Celadon, but only after defeating the many defensive bases.
This gives us anywhere from an Earth day to an Earth month to react. I only have a few stunning-level weapons to combat it, so I can't finish it easily. The Soulswords may stall it for a while though.
