Super Smash Bros 4's Pic of the Day earlier this week revealed a new powerful attack for King Dedede.

In the picture Dedede is seen standing with his mallet as its partially transformed into a rocket of sorts. Pikachu is on the floor behind the King, and looks to be roughed up.

"So far, which attack can blast away enemies most dynamically "¦ Is it King Dedede's fully charged Jet Hammer? Nah, it can't beat [Little Mac's] K.O. uppercut," game director Masahiro Sakurai wrote on the Nintendo Miiverse. See a picture here.

Speaking of Little Mac, yesterday's Pic of the Day featured the diminutive boxer as he showed off his left and right hooks in his finishing move attack.

"Pic of the day. Little Mac's side smash attack is his straight right punch...but it can transform into an uppercut if you tilt diagonally upward, or a body hook if you tilt diagonally downward. The body hook is the most devastating of these moves and it doesn't blast the opponents away," wrote Sakurai on the Nintendo Miiverse. "The trick in activating these punches is to avoid tilting the controls diagonally from the get go--instead, tilt up or down right after the smash attack starts kicking in. You can also tilt up or down while you're powering up." See the picture here.

The characters confirmed for the game so far are: Mario, Luigi, Link, Samus, Kirby, Fox, Pikachu, Bowser, Donkey Kong, Pit, Olimar, Toon Link, Princess Peach, Sonic the Hedgehog, MegaMan, Wii Fit Trainer, Rosalina, Zelda, the Villager, King Dedede, Lucario, Little Mac, and now Diddy Kong.

The game is expected out sometime this spring for the Wii U and 3DS, however, Nintendo has not confirmed the date yet.
