The Kyuubi. His chakra sucks the air out of the room. People have made more comments about his chakra more then anyone else. After that, probably Madara, A, Kisame. Apparently theirs is very intense.
imo opinion it's tobirama.......he looks like swag it's self. i haven't seen him fight or anything but i could just imagine him fighting someone while looking calm and saying you could never touch my swag the whole time. tobirama looks like a boss.

1st Madara. Tell me one thing he did that wasn't Badass? Remember what stance he had when he first showed up ? He was like " YOLO ? Bit ch please " . And then like " Weak people are ugly, and weak senju are even more ugly ".
2nd Tobi. Something like Madara, just not that much of Badassnes.
