Devil Cars appear as enemies in Smash Run. If fighters are close by when it has stopped moving, it'll spout exhaust fumes that cause paralysis.
A fearsome enemy from the Mother series, this car attacks mercilessly, closing in on fighters before trying to hit them as it spins doughnuts. No, these aren't the kind you eat---they're the kind that hurt. Its exhaust fumes can cause paralysis too, so keep your distance until it's between attacks.
