I could stop this list now and just knight Big Bang as the fiercest, but what fun would that be?

They haven't officially debuted yet, but you know YG's Winner is definitely fierce.

Block B? More like Block F(ierce).

B.A.P is definitely a unique and fierce group.

B2ST are truly a bunch of fierce beasts.

BTS, Bangtan Boys, are rookies but undeniably fierce.

Jay Park isn't a band, but he's pretty badass fierce.

Hip-hop trio Aziatix is currently MIA, but it doesn't take away that they are pretty darn fierce!

You know what's crazy? Almost every single one of these fierce boy-bands starts with the letter "B." Isn't that strange? Who is your choice for fiercest boy band?
