Different people wrote them, and they are called "joke" analyses. Typically, a select couple comedians, like cookie (who wrote BW Magikarp), are chosen for that task.Who wrote Luvdisc's DPP analysis, and did the same person write Sunker's DPP analysis?
Also, can I get to know all the analysis he/she has written on "shitty" Pokemon?
This question would be better asked in C&C. There's an SQSA thread there too.
