The large-scale structure (LSS) of the universe is comprised of galaxy filaments, tendrils, and voids. The majority of the universe’s volume is taken up by these voids, which exist as underdense, but not empty, regions. The galaxies found inside voids are void galaxies and expected to be some of the most isolated objects in the universe. However, their standard morphology remains poorly studied. This study, using the Galaxy and Mass Assembly (GAMA) survey and Galaxy Zoo’s SDSS survey, aims to remedy this. To do so, survey results from GAMA have been plotted using the Sérsic index (n) to analyze morphology, while data from Galaxy Zoo’s crowdsourced study supplies a second analysis. For completeness purposes, we only include void galaxies identified by Alpaslan et al. 2014 with a redshift (z) between .08 and .215 and stellar mass (M*) between 109.35 and 1011.5. We then utilize Kolmogorov-Smirnov (KS) testing for significance. As a result, we conclude that, as supported by previous literature (Kreckel et al. 2014, Beygu et al. 2015, Beygu et al. 2016, Fraser-McKelvie et al. 2016, Pustilnik et al. 2019) , most void galaxies have a disky morphology with Sérsic index n
