Like blissey can have be the most specially defensively bulky Pokemon in the game with 255Hp and 135SpDef. So how about for defense?

So you want to consider both hp and defense, well then Regirock wins. Base 80 hp and base 200 defense make it the most defensively bulky golem around. Steelix comes in at a close second though, with base 75 hp and 200 def, and arguably has a superior defensive typing. Next comes Aggron, with 70 hp and 180 def. honorable mentions go to deoxys d, shuckle, cloyster, forretress skarmory and many more Pokemon who are defensively bulky in their own right
Giratina can survive Banded Zekrom Outrage with max HP and Max Def. Lugia with Multiscale unbroken would also be able to take several hits.
