Gavla was mentally challenged Matoran
Gavla thought she was hot and that everyone had crushes on her. She stayed like this all the way through high school until she graduated and found herself alone.
Gavla was then offered a job modelling as the director was blind and always got the costumes mixed up. This resulted in Gavla modelling an outfit made entirely out of raw meat.
When her failure was published in 'EPIC FAIL' magazine, Gavla turned to Vamprah for help, but Vamprah didn't care and sold her on ebay. She is currently being shipped to Taiwan when some lucky kid will get to use her to clean his toilet.
Later, the Matoran Nui came to Taiwan and ate her.
