I have all three games in the series. The characters I use in Brawl is Fox, Falco, Olimar, and Mr. Game & Watch. I remember a lot of people were surprised when they found out that Falco's final smash was the Landmaster, instead of the Arwing. If a Lemming was in in this game, what attacks will it have? I only played the original/PSP Lemmings and not much of Lemmings 2, so I don't know how the skills work in that game and there's a lot of them.
Forward Smash: Miner
He'll swing the axe down once
Side B: Basher
When there's no one there, he swing his arm and do nothing, but when you do catch someone, he'll hit the enemy like he's bashing a wall like in the game while moving forward and he'll continue hitting them until he reach a wall, edge, gets hit, or you can make him stop.
B: Paintball Gun
I haven't played this game but I know it exist, so I thought it will be good to have a projected attack.
Final Smash: Trap Level
A Lemmings level will come down with many traps like the flamethrower, noose trap, lava, and rocks. There's also Lemmings walking around and they will blow up on you with the bomber, so you can't just stay in one spot. When you get hit by the bomber, it can easily kill you.
That all I can think of right now.
