An arena packed with beauty queens... I'm scared to go in there.
Bonding is a power introduced in Season 2.
Bonding is a phenomenon where a strong connection is created between two magical creatures, whether it be emotional or empathic. From the very moment two creatures bond, they become almost like family, and their powers are strengthened, sometimes to such a degree where their magic is increased exponentially. In some cases, bonding can even restore magical energy to one of the creatures involved.
In "The Shadow Phoenix," Concorda meets Bloom and tells her about bonding. It is a deep, somewhat rare connection between fairies and pixies. It is a bit like falling in love, and the two become inseparable, just like twin sisters. Concorda says it is a very special thing. She also reveals that she is bonded to the Magic Archive.
In "Magic Bonding," the captured pixies rejoin Aisha with her new friends, Bloom, Stella, and Sky. Stella bonds with Amore and Bloom bonds with Lockette. Aisha explains bonding as "love at first sight" to Sky.In "The Mysterious Stone," the rescue group and the pixies arrive at Alfea and join the Winx. Three pixies bonded with the Winx on the spot. Digit, who had met Tecna in a chat room prior, finally meets her face-to-face. Tune and Musa bond over sense of style, and Chatta gossips to Flora.
The Shadow Phoenix
Bonding is only mentioned briefly during the pixies retelling of major events in Monsters on the Loose when Lockette, Amore, Chatta, Tune and Digit talk about how they were able to bond with Aisha's new friends, the Winx Club.
