Non-Outsiders for Gate?

[Corsair]

Synopsis: I am looking for the best extraplanar creatures of 40 HD or less to call via Gate that are not outsiders.


Background: I just learned the spell, I have a CL of 20 (so one 40 HD creature). We will soon be fighting a tainted solar wielding an artifact that makes him very deadly against other outsiders. I want to use Gate, in part because this is one of the last times I'll be playing this character and I want to feel like I got to use all of my powers.

So the question is: What is the best extraplanar non-outsider for 40 or less HD that I can call?



Best options so far look like the various planar dragons in the Draconomicon. Anyone have any other suggestions?

You could try an abomination (epic section of the SRD), maybe.

Assuming the DM allows you to call in unique entities, there are always some of the more powerful inner planes critters: the archomentals, the wanna-be archomentals in the para and quasielemental planes, the freaky-big brine dragon in quasielemental salt, and the ever so enigmatic Sun Sing. Beats the hell out of me what their published stats are for HD purposes off the top of my head, though only a minority have ever had published stats, 3.x or otherwise.

Except unique creatures can resist a Gate, and even if they do choose to be called, they are uncontrolled.
