If you could have any 1 unit from FE games before Path of Radiance put in the game, who would you pick?

Oviously Vanessa from FE Sacred Stones.
Cuz she is my second waif.. I mean my second favorite character overall after LUTE THE GODNESS

Altena. The rest of her family is in

Pent.
He's cool, styleful and badass.
The true mage general.

Related to him, I'd love to have Louise get in the game at the same time (they have to) and Athos is a perfect unit as our first armored mage in the normal summon pool (preferbly with Aureola as an anti dragon tome)

Erk, but he needs to be terrible, so that he gets demoted and then whenever I pull him I can say he "erks" me!
