Yes, that's Lucario and Pikachu!
Oh, and did I say Snake and Samus beat Ike and Marth in Round 2?
I meant Lucario and Pikachu did(BTW, Pikachu can't talk human like Lucario can, just so you know)
And also, this is the MIDDLE of their fight, same goes w/ Link&Pit and Jigglypuff&Wolf(Oh boy, that has to be the WORST combo ever...Jigglypuff and Wolf XD)

And yes, that's a Smart Bomb(the red thing that has a 'B' on it, for those who don't know)Pikachu was holding and throwing at Toon Link...
