Shiela

Shiela was a normal cockatiel until an encounter with ZELDA GAS (huh?) killed her owner and mutated her into a giant monster! Shiela tried to destroy the source of ZELDA GAS (still huh?), but fought Ultraman Tiga along the way. THough interestingly, Shiela succeeded in the end, and Tiga didn't kill her, instead letting the giant mutant parrot fly off to safety.

 

The spelling just bugs me.
