Trivia

So the giant smash with knuckles animation was a drop kick (note that this is only a cosmetic animation and it's not an actual drop kick, just Smash with a drop kick animation instead of traditional ones). The animation can be seen from Korean Mabinogi promotional videos but soon after (I think it was G7) DevCat changed it to a headbutt for males and a knee to the face for females.

The videos in question:

Male Giant: Time frame around 1:13. It's hard to spot but it's the Giant that drop kicked off of the Giant Bandersnatch. He's wearing a knuckle but the frame is fairly hard to see and the video is blurry. http://www.youtube.com/watch?v=TtP6Psg-gmQ#t=1m13s

Female Giant: Time frame around 0:51. The female giant drop kicked off of a Wendigo and you can clearly see her equipped with Hobnail Knuckles. www.youtube.com/watch?v=W9heKfoDkWw#t=0m51s

NA Mabinogi essentially never saw these animations because DevCat removed it for some reason.

Much better video for giant male: http://www.youtube.com/watch?v=VtSY3pIwe_4

And that female video was strange. It showed smash twice, once with the drop kick and another using the smash animation we've always had for knuckles - a strong right uppercut.

Oh right it was an uppercut, the knee to the face was bare hands. Well I guess it's because when they were making the video they changed it while making the video so there are inconsistencies.

Yeah knee hit is still the barehand smash.
