What's your favorite. Please give name of the game and the number stage it's in, as well as the reason.
I'll start:
Game: Crimzon Clover
Stage: The 4th Stage
Reason: Awesome bullet pattern and you're destroying a Big Mecha Ship and not some type of poorly drawn girl that have very strong skin (Looking at Touhou, why do I get off track so easily? :P). What make this boss stand out is that in the 2nd form, the boss literately start getting help from 2 other ship so you will have to dodge TWO bullet pattern instead of one crazy as heck bullet pattern. If cave would to own rights to this game, then Queen Larsa would be laughing historically while controlling this big ship (I would be if I were controlling some big ship that have weapons that even the US army don't have).
