Double Team

Double Team is the down special move of Lucario in Super Smash Bros. Brawl, acting similarly to Marth and Ike's Counter attack. When the attack is used, Lucario will take a one-footed stance, and will split into two copies of himself. This, however, will not do any damage unless an opposing player happens to attack him shortly after Lucario uses Double Team. If an opponent attacks Lucario the instant or shortly after Lucario uses Double Team, Lucario will disappear, reappear behind the attacker, and slide kick into him, countering the move. However, it only works if the attack is used just before being attacked, as it will not work if kept in action for too long. The power of the counter attack is increased accordingly to the damage Lucario has taken.

In Pokemon, Double Team powers up attacks, but doesn't actually unleash an attack.
