These are Chewbaccas mixed up with historical figures from the murky past (or present).
Sir Francis Chewbacon
Who do you get when you cross one of the fathers of the scientific method (who is also rumored to maybe be Shakespeare) with one of the fathers of the rebel alliance (who also happens to be a Wookiee)? Well, you get Sir Francis Chewbacon!
And that's the last Chewbacon from our Chewbacon Tryptic! Thanks for playing.
