After getting hit with the breath of fresh Haste from Arowain-kitty, Mok-Tar strangely doesn't seem to go any faster (Armor of Speed), but nods in thanks as his eyes start to glow, his growl takes on extra resonance and he gets his groove on:
Karnak (the cohort) casts Teleport on himself and Mok-Tar, dropping them 100' away from the Big T. He then casts Righteous Wrath of the Faithful.
Mok-Tar quickly activates his Charm domain power as a free action (+4 to CHA).
He concentrates a moment, and grows in size to near-Tarrasque-proportions (Gargantuan) (quickened action, Sizeshift).
Then the Cat-Man-O' Destruction begins a jagged charge (because he can) traveling a zig-zag that spells out the letter M, while pulling out his shields from the Haversack and readying them, uses Iajutsu Focus on the maneuver, getting an 8 (50 total=9d6 damage each attack).
He manifests Divine Might (free action) and Divine Shield to power them up. (free actions - that last one only is a stretch to me, tell me what you think).
He feels the inner power protect him (Divine Armor, quickened free action from Quickened Divine Channeling), as he increases his baseline Rage (Persistent spell) with his own Lion's Fury on the build-up to his full attack on The Tarrasque.
Feeling like he can nail the Big T easy enough, he shifts into Super-Power-Cat-Attack mode
TM (full Power Attack with a Power Lunge during a Shield Charged-Lion's Pounce). (the Power Lunge gives up an AoO to the big guy - maybe his only attack he'll get.)
Current HP: 226
AC: 78 (+8 Rhino Leather armor with Magic Vestment, +2 large steel shield, +12 Dex, +2 natural, +4 Haste, +5 Deflection, +27 Divine Shield, +27 Divine Armor, -2 while charging, -2 while in Lion’s Fury, -4 Gargantuan size, - 11 Reckless Attack)
DR: -
Resistances: -
Immunities: Disease
Saves: (approximately) Fort +46, Ref +45, Will +40
Defenses: nothing special
# of attacks: 12 (Righteous Wrath, flurry of blows, Wild Fighting, MWF & IMWF with 4 arms)
Attack bonus: +41/+41/+41/+41/+41/+41/+41/+36/+36/+36/+36/+31 (11 BAB, +20 STR, +27 Divine Shield, +2 while charging, +2 RWotF, -2 Multi-Weapon Fighting, -2 flurry of blows, -2 Wild Fighting, -4 Gargantuan size, -11 Power Attack)
Damage: 4d6 (Gargantuan Bashing shields) +20 STR, +20 Power Lunge, +27 Divine Shield, +27 Divine Might, +10 Spikes, +2 RWotF, +11 Power Attack and +11 Reckless Attack = (rolled 4d6, got 20) + 128 = 148 on one hit x 3 for Rhino Armor and Shield Charge = 444 for one attack.
He had 12 attacks, guys.
If all hit, the shield damage rolls are 24!, 19, 17, 12, 16, 12, 15, 14, 13, 17, 19.
That'd be 456 (heals 278 damage to Mok-Tar and does -1d4 negative levels on the Tarrasque), 441, 435, 420, 438, 420, 435, 432, 429, 435, 441 = 5226 damage.

The healing is from Wrathful Healing, and the -1d4 levels is from 2 Energy Draining shields (DotF, as Enervation spell), which hit the Tarrasque 7 times (rolls of 4,2,2,2,1,2,2 = 15 negative levels conferred on Big T)
The last few hits, Mok-Tar would have been using Improved Shield Bash to try to move the 130 ton bulk 5' with each hit (how unbelievable is THAT?!). STR check rolls of 7, 13, 2, 2 (STR check + 20 STR bonus + 2 charge bonus).
Big T has +4 size on Mok-Tar, and +4 stability bonus for 4 legs.
Does he go flying? (Can he beat a 29, 35, 24, 24?)
Damn - I forgot the 9d6 Iajutsu damage per hit (not multiplied).
Well, if all hit, 9d6 x 12 attacks is 378 more damage (as if it makes a difference)

I also didn't include the Lion's Shield's attacks (what bonuses exactly would they have had here?)
Mok-Tar finishes his full attack, then uses his Hasted partial action to ham it up for the crowd, his four arms adopting a Heisman-trophy stance, then clunking the shields together loudly - ahh! He'll do a Lion's Roar, to Panic anybody nearby (mice, etc)

Him? Again?
That's the quote of the thread right there... that's hilarious.
If only the Tarrasque had a 4 INT - I was sorely tempted to use Distract on him (I can just picture it :
Mok-Tar winds up his Shields, while pointing up to the Sky and yelling at the Tarrasque "Hey! It's Elvis!")
