C4 is the down special move of Solid Snake in Super Smash Bros. Brawl. When used by pressing while tilting the down, Snake plants a C4 on the ground. Activating the move again causes Snake to pull out a remote and detonate the explosive, creating an explosion that deals strong damage to any enemies in its vicinity. If Snake is close to a wall, the C4 is stuck onto there. The C4 can also be stuck onto opponents if they're close enough while Snake plants it, and it can be passed between characters by coming into contact with them. The C4 can also be knocked off if the character that is holding it is hit with a strong attack, and eventually falls out on its own after enough time has passed. Using the move in mid-air causes the C4 to quietly drop straight down. If Snake is attacked before he pulls the trigger, the C4 does not explode. If the C4 isn't detonated after about twenty-six seconds have passed since it was planted, it blows up on its own. Snake's C4 has a one in six chance of being a butterfly-shaped C3 that is otherwise identical; this is a reference to Metal Gear Solid 3: Snake Eater, when Naked Snake molds a heart-shaped C3 into a butterfly.
