Well, I'd have to say my two would be Tennimon 
and Toward the Terra.

As for the cels...erm...well, that's a lot 
harder. I have an Eros in there that I would 
never let go, but at the same time my pan cels 
and my Mik and Raph cels are very near and dear! 
EEEK! ::explodes::

OK, done now o.O I've chosen, but as I am a 
fickle girl, don't plan on this staying in this 
order forever ^^

P.S. - The Toward the Terra cel is of Soldier 
Blue! WHOO! Yay for old school bishies!
