Fun Sub optimal level 20 gesalt?

[CyberThread]

So I utterly do not want to be a level 20 Wizard /Warblade

I would like some ideas though on something that allows me the freedom to be something unusual and WTF , in a roleplay based game when I have this many levels to mess with.

I had fun once with an anthropomorphic bat psywar 20 // ghost 5/totemist 2/unarmed swordsage 2/factotum 8/swordsage 3.

I took the Illithid Grapple feats for tentacles (as well as the Form of Doom power) so that when I possessed enemies they exploded into tentacles and proceeded to eat face.

He was the stillborn spawn of Cthulu.

It was awesome.
