I'm suddenly thinking of that one giant walking construct dungeon in Final Fantasy 4.
Final Fantasy IV had the Giant of Bab-il (SNES American translation).
And it was basically a planet-attacking monstrosity requiring multiple kingdom's of high tech armies to check it before you to infiltrate. It's basically an elder evil, but old school.
That Mogo picture makes me wonder if he had an evil counterpart? Like Atropus, the elder evil. I wonder if we could reverse-engineer the actual atropus stats from the aspect stats. The little (gargantuan) aspect has 58 strength... The real deal is 700miles in diameter.
Hmm. reverse engineering the "aspect" template via FCI web enh:
-11 to -14 CR (-33% to -66%)
-aquatic if its a non-main subtype
-size to become Large if larger (adjusts natural weapons), -5th subtype
-1 langauge sometimes
-lowlight or true seeing (sometimes replaced by see invis) unless incorp, usually -scent xor -75% darkv' if high
100 telepathy max (generally 300' prior)
-11 to 16HD (-50% to -75%) skill & stat ratios are fairly exagerated rather than constant mod ratios
fast heal 5 max (generally 10 or 15 prior)
-50% DR but type stays the same
-50% (sometimes -66%) nat if above 7 otherwise min of 6 (size change are in addition to this)
-1 [M-A] unless central to fluff, type trait, or energy immunity if corporeal
-100% SR (~13+HD)
-33% move speed (rounded up) if more than 40', not to reduce fly below 60'
-2 or 3 of the stronger natural attacks or -magic armor unless central to fluff. -50% natural attack if only attack
-50% enh on weapon
-100% SA except action advantages like gaze/swallow which loses about 50% of its effects
-1 or 2 SQ (-50% aura range if kept)
-14 to 18 SLAs (-100%) unless important to concept, then only 1/3 remain at about 50% strength
feats are generally the non-advanced version, although weaker feat versions of SA might be needed
Lastly, stats are about -33% to -50%
Reversing that is tricky since applying the pseudo template removes information similar to derivatives. So when we integrate back the original (x^1 +C -> x^0+0), it won't be exact. Still it's close enough if you assume the original to not have absurd starting values in the grey area. Here's the real Atropus' stats:
CR46 to 69, 132 to 264HD (which add skill ranks), fast heal 30 to 60, DR 30/epic & good, Colossal+ x15, Undead (evil), blind, blindsight 500' to 2000', unlimited range lifesense within the plane, 60' negative energy aura, atleast 3000' telepathy, 55 to 76 nat, SR 145 to 277, 4 8d8 slams /w death crit & con plus energy drain at atleast the same relative strength, 150' fly, up to 36 more SLAs, 1 to 2 more special qualities, and stats of atleast 58,13,0,25,24,31 with a total between 302 and 453. I suggest 90,20,0,40,50,108 or 114,29,0,50,90,170.
Good luck not cheesing that 3.4k hp.
It also has low gravity, can eat you, and has a non-impulse engines speed of 40,000 ft (2,438 m/s)
