[DC] How powerful is Space Ghost, relative to the other DC heavies? Does his universe intersect with any of the familiar ones?
gpt
He isn't powerful at all in the strength department. He uses arm bracers that have buttons to do various types of blasts and force fields. He also has a belt that allows him to go intangible to go through walls (Space GHOST). He has had extensive training in weapon use and hand-to-hand combat but he does not have super strength. 

Space Ghost is an intergalactic peacekeeper thus he was made to use his wits and gadgets instead of "Hulk smashing" everything. 

As for the universe intersecting with other DC characters, yes. Space Ghost was featured in Batman: Brave and the Bold Episode "Bold Beginnings!" where he and Batman team up to battle the Creature King after he captures Jan, Jayce, and Blip.
