Each boss has a specific item they drop. The item is usually used to create a new crafting table, which will allow you to build a star map upgrade and travel to a different sector. (EX:The Active Robot Boss always drops a processor, which can be used to craft the Robotic Crafting Table, which, in turn, can then can be used to craft the Starmap Upgrade MK3.)
Note: Bosses as of now are summoned to advance to new tiers and sectors, whilst "Mini-Bosses " can be found on planet surfaces.
