Ritual of Alignment (Evil) + Cancer Mage, fetching Festering Anger and Vile Rigidity, can get us infinite strength and infinite natural armour. Alternatively, I can use the Armour as DR option and get DR 1/- for every 5 points of natural armour (which should be more than enough). This leaves non-physical damage types, a bunch of miss chance, and probably Improved Evasion/Mettle.
I know, I know. Ritual of Alignment and Cancer Mage aren't exactly the most lore-sensitive options. But it's easy enough to style these as being why he went bald and got his powers, and there'll likely be more templates to add to the pile. He's probably not going to have all that many hit dice; he's just an ordinary guy, after all.
