Bin

Bin is the main protagonist of Dynamite Dux.

Appearance
Bin appears as an anthropomorphic duck with blue feathers covering his body, a white pair of gloves, a red bow tie and large red shoes. His feathers form a tuft similar to hair atop his head and his tail feathers are long and unkempt.

In the Master System version he starts as a blonde haired young man with a blue jumper and a red bow tie before Achacha transforms him into his duck form.

Dynamite Dux
Bin has two different histories depending on which version of the game you play:

Arcade version
Bin and his brother Pin are pet ducks owned by Lucy. One day they are playing together in a flower field when a dark shadow appears, transforms into Achacha the Great and kidnaps Lucy by trapping her in a miracle ball, before vanishing to the Achacha World. Bin and Pin then travel through the dimension door left for them to come fight Achacha and make their way through several real world locations, defeating bizarre enemies along the way.

Eventually Bin does battle with Achacha whom he manages to overcome, defeating him and forcing Achacha's spell to dispell. Bin and Pin are sent back to the flower field and Lucy is freed from the Miracle Ball, allowing them to celebrate together.

Master System version
Bin is Lucy's human boyfriend, and whilst out on a date in the flower field, they are attacked suddenly by the appearance of Achacha who transforms Bin into a duck and traps Lucy inside a Miracle Ball. The rest of the game plays the same, but without Pin.

After defeating Achacha, Bin is given a doorway back to the flower field. Achacha's spell wears off and Bin returns to being a human, as Lucy is returned to normal size and freed, allowing them to continue their date.
