"The bad boys from the 80's are back, and they have created the ultimate weapon. The Blacktron Dreadsphere! While not powerful enough to destroy an entire planet, it boosts enough firepower to lay waste to the Lego universe. Monorail Transport: destroyed. Space Police: obliterated. Galaxy Commander: space dust. The ship does have a drawback however, it consumes a lot of energy, and will need to make frequent trips back to its recharge station to regain its full lethality."
When I was making my Asteroid Miner creation I thought the asteroid looked a lot like a Death Star. But instead of converting it into an exact Death Star, I made it into a Blacktron version, to fit into the Lego space universe. I also made a recharge station, which doubles as a stand for the ship. The ship can hold 2 minfigs, and has rotating guns on the front and top. The superlaser can rotate as well.
Thanks for looking! Comments or questions welcome.
