Super Mega Fist - What would the damage be for a colossal character?

[Triskavanski]

So I saw some epic feats and one of them increases your unarmed damage to 5d10 at the level I'm at as a medium creature. But what would that damage be if we amped up to a colossal sized critter? (Say for example Mighty Whollop)

[icefractal]

Damage doubles every two steps, so for four steps it would bring it to 20d10.

Take a look at this, http://www.dandwiki.com/wiki/Ultimate_Monk_(3.5e_Optimized_Character_Build).

you can get up to 256d8 if your planning into epic levels
