Care Bear Stare and Cousin Call
The Care Bears' ultimate weapon is the "Care Bear Stare," in which the collected Bears stand together and radiate light from their respective tummy symbols. These combine to form a ray of love and good cheer which could bring care and joy into the target's heart. The Care Bear Stare has several different looks. One has a beam coming from the tummy being made up of several replicated images of the symbol. Another variation forms a rainbow when multiple Bears and/or Cousins are involved. A yellow beam with red hearts is sometimes seen as well. The movies Journey to Joke-A-Lot and The Big Wish Movie do not feature the Care Bear stare, but it does return in Oopsy Does It!. In the new series, Care Bears Adventures in Care-A-Lot, the stare appears as a beam of light in the color of the bear from which it originates.
In the original animated specials and the DiC series, the Care Bear Stare is usually initiated by the phrase "Care Bears...prepare to stare!" while in the Nelvana series and later versions it is initiated by the phrase "Care Bears Countdown!"
During the movies, the Care Bear Cousins call their weapon the "Cousin Call." In the second movie, the Call looks like a musical score, and the cousins, excluding Swift Heart Rabbit, use whatever animal noise is common to that animal. In the first movie, the Cousins simply make animal noises since they do not have any tummy symbols; those are later given to them by the Care Bears at the end of the movie.
Although commonly used on villains, the stare has also been used on the Care Bears themselves at least once in Adventures in Care-A-Lot, when it was used to temporarily cheer Grumpy up in the episode The Tell-Tale Tummy.
In addition to the Care Bear Stare, the Care Bears can also use their tummy symbols to summon other assistance such as heart-shaped balloons, rainbow bridges and sending out a distress signal.
