Knights are the basic protector in sector 9. They are found in most worlds, but mostly Grasslands. They can't be smashed (because they are NPC's), but they have a low attack of 2.

In some missions in grasslands, King Grassalazar will give you 2-3 to help with your mission, but in this instance they can be smashed with an HP of 8 and a raised attack of 3.
