Born in Saint Canard, USA, I was raised by Doctor Eran of Canard University. He taught me about science and medicane and mechanics. So, when I turned eighteen, I attended CU with my girlfriend, the lovley Miss Gosalyn Mallard, daughter of Drake and Morgana Mallard and sister to Drake Junior.
When I turned nineteen, she and I began working on experiments to help strengthen both the mind and the body. Of course they failed, but science isn't perfect. It wasn't until Lucky Experiment #86 that my life changed. I was able to create a serum that can fight off any disease, as well as increase muscle size. I injected myself with the serum, than installed an iGlad to my chest to regulate the serum.
What happened next though...
I took Gosalyn and her familt out to dinner, when a crazed bully named Megavolt attacked, claiming Drake was Darwking Duck. And he had nearly killed Gosalyn trying to proove it. But when I tried to stop him, he bar-b-qued me with at least a few dozen volts. This messed with the iGlad and sent a shock throughout my body. The serum increased my body mass to a massive level, as well as boosted my adrenaline!
I save Gosalyn, some how, but I nearly died due to the adrenallin increase. Luckily, Gosalyn and I redid the iGlad to regulate my body and to control my secret identity: Corsa.
Which is "rush" in Italin.
