Hello Rayman, I'm Betilla the Fairy, and I'm going to help you in your quest. I can give you a new power.
Now you can punch with your fist. Good luck! Press the □ button to punch. The longer you press, the further you punch.
The telescopic fist is the first power that Rayman is granted by Betilla in the original Rayman game in Pink Plant Woods. It is his most widely used power, and with it, he can hurl a fist that defeats any enemies that are in his way. Another power, the grappling fist, allows Rayman's fist to grab objects such as extra lives and flying rings. It can be powered up by picking up gold fists, which doubles the fist power, and speed fists which makes him throw it faster. Picking up more speed fists, up to three, will further increase the speed. Rayman can also increase the power of his punches by either charging the fist or punching while jumping.

In Rayman 2, Rayman shoots energy balls instead of throwing his fist when attacking. However, at the beginning of Rayman Revolution, he is temporarily given the ability to punch by Globox. This power only lasts until he frees the Grand Minimus in the Woods of Light, where he is given the shooting power as in the other versions of Rayman 2.
In Rayman 3

The telescopic fist returns in Rayman 3. Rayman can shoot it laterally by strafing around enemies. The fist can be upgraded temporarily by the Laser-Washing Powder cans some Hoodlums leave behind. Using his fist isn't his only means of attack in the game. Rayman can also kick his opponents if he is close enough.
The telescopic fist can be used offensively against most enemies in the game, barring the Knaaren who do not take damage against it and can only be evaded. The stilts of the Stumbleboom are also resistant to Rayman's telescopic fist, but can be destroyed if the Vortex power-up is active.

Rayman uses his telescopic fist in the Game Boy Advance version of Rayman 3 in a similar manner to how it was used in the original Rayman game, with him being able to charge his fists for stronger attacks or just throw them normally. Throughout the game he will receive several upgrades for his fists, such as being able to throw both at once, grab Purple Lums and charge the fists for even stronger attacks.

In the Nintendo versions of Rayman Raving Rabbids
In the Game Boy Advance version of Rayman Raving Rabbids, Rayman's fists behave as they did in the Game Boy Advance version of Rayman 3, but without any upgrades except for the one to grab Purple Lums. He starts out the game without his fists, though quickly finds them after escaping.
In the Nintendo DS version of Rayman Raving Rabbids, Rayman is able to use both his telescopic fist and shoot Yellow Lums. However, his telescopic fist functions differently in comparison to most titles. His fist does not retract when shot, nor can it be charged. It deals half the damage of Yellow Lums and can't defeat all enemy types. Unlike Yellow Lums it can however be used an infinite number of times.
In Rayman Origins and Rayman Legends
Rayman begins Rayman Origins with only the ability to jump on enemies to defeat them, this is quickly rectified as Rayman and his friends rescue Betilla in It's a Jungle Out There..., who then gives the heroes the ability to attack. Unlike past titles, where the telescopic fist was Rayman's primary means of attack, Rayman is now able to perform a variety of attacks and combos. The telescopic fist remains accessible to Rayman by holding down the attack button, and releasing, as it behaved in past titles. Other heroes also have attacks that are functionally similar, but aesthetically different, Globox attacks using slaps, while Teensies attack using magic.
The attack power is retained in Rayman Legends, all previous characters use the same attacks, barring the ground kick move, which is changed to a ground slam move.
