Favorite Improved Familiar

[Ninjaxenomorph]

I am asking several things here:

1) If you have ever taken Improved Familiar, which worked best?

2) What is your favorite?

Never taken it myself, but I am partial to the Arbiter Inevitable or Pseudodragon, fluff-wise if not mechanically.

[Nemitri]

I like the pseudodragon, and the faerie dragon.

[Interzone]

Absolute favourite for me is definitely Lyrakien Azata.

Although my favourite for an evil spellcaster is the Cythnigot Qlippoth.

Both of them for both fluff and mechanics.

[Noir le Lotus]

I like the silvanshee and the imp.

[Maddigan]

Tinkerbell is my favorite Improved Familiar.

It makes me sad there aren't any medium sized improved familiars. (If there is and I missed it, I'd certainly appreciate the link.)

My all-time favorite was a gnome who would frequently get high off of his fairy dragon familiar's breath weapon (euphoria gas).

As far as 'best'? Imps. They are *terrifying*. Their at-will invisibility and tiny size makes them incredible spies, and with the proper build they can be effective wand snipers with use magic device. Toss in a weekly commune and it's hard to go wrong... apart from RP issues that the GM may throw at you for voluntarily consorting with a servant of Hell and possibly being an unknowing agent in various fiendish plots.
