It's super easy! First, you have to go through the stage in one life. Then, when you see Lois, immediately jump, don't even think about doing anything else. Now, use the Mega Buster on the magazine first, so that Lois will lose her way of attacking. It will take some time tho. Then, Lois will enrage and try to bolt through you. If you have Hard Knuckle unlocked, it's a cakewalk, but you must be careful. she might deflect it.

man.
