1. Figaro ~ I always thought it was a bit odd they just re-used Figaro for the shorts, but I love Figaro, so I'm happy about that.
2. Scrooge McDuck
3. Donald Duck
4. Max Goof
5. Clara Cluck ~ This character always made me laugh growing up.
6. Pluto
7. Goofy ~ I like him better in A Goofy Movie and Kingdom Hearts than the old shorts.
8. Chip n Dale ~ I liked them in the shorts and in Rescue Rangers. Their shorts were always hilarious, just for driving Pluto or Donald berserk.
9. Mickey Mouse ~ KH is the only time I ever really liked Mickey, tbh...
10. Ludwig von Drake
Looking on Wikipedia, I suppose the DuckTales characters count as core characters, too, just like Max. But it still feels weird to include them aside from Scrooge and the nephews, who are featured in other things besides DuckTales... Magice de Spell would definitely be my #1 if we were to include them.
