Page 320, Yaum Al-Qiyamah is a bit broken... Should probably be set to a hard-set Total Points value of 500 instead of 676.
There is 120 points for Invulnerability, and it's not even used down in the Defenses because it only calcs Light and Heavy Armour... Ideally, it should probably be set to Invulnerability 9hd if you wanted to spend the 676 instead of capping it at 500. Or for cost-effectiveness, you could drop it entirely, raising Heavy Armour and Light Armour to 10hd each...
However, he got past security and made it to the Tower without being detected... I'm thinking this could easily be done through using the Combat Fugue in Godlike... Attaching his Hypers and Miracles to a single 2HD Miracle that "turns on" the others... Reducing the Permanents to Endless would then give you the same time levels, but again, reduce the cost immensely. Invulnerability with Attached, and Endless instead of Permanent, reduces the cost from 20 per die to a staggeringly low 12 points per level. The total cost of the current Heavy/Light/Invul is a whopping 298 points. That's enough to take Invulnerability to 10hd with 58 points left over. Combat Fugue with Useful, Endless, Self Only, and Depleted (maybe require prayer for this holy martyr to replenish) and for 4 points, you have 2HD (Combat Fugue being an on/off switch for his Superpowers and thus letting him walk around as a mostly-norm most of the time).
Reduce the cost of Hyper Body and Native Body due to being also Attached, and you save another 20 points. Regeneration Attached saves 8 points.
Invul should probably be 7hd with the way he's described, so we save 130 points there, 28 for the other Superpowers, 158 in total. His Archetype changes to Themed and with his Willpower level, we can reduce that cost to 0 with No Willpower No Way, and we've cut 173 points off the 676 for a new total of 503. Reduce his Base Will to 23, and it's a 500 point character that is actually stronger than described (purely because Invulnerability wasnt taken into account).
If we want the 9HD HAR and 8HD LAR, we can remove the Immunity stuff entirely, saving 14 points and raise Invulnerability to 8HD.... Could go even higher with the Obvious Flaw, having bright glowing sparks fly off of any place something/someone hits him.
As for Errata: his Defense is ignoring his Invulnerability.
