If you could have anyone and anything become a potential follower who or what would you have?

For the sake of creativity the only people or creatures you can't choose are all current followers, such as lydia, serana, etc. and Vigilance/Meeko.

I think it would be sweet to have a Steam Centurion follow you around, on second thought it constantly clanking would get pretty annoying....

I guess what i would really like would be a snowy sabre cat, who/what would you guys like?

1. Paarthurnax.
2. A giant.
3. Mehrunes Dagon.
4. Alduin.
