It's possible to use the Shinespark to deal devastating amounts of damage (often being enough to kill a boss in one hit) to several bosses in the game, with known bosses it can be performed on including Spoiler:the Central Units, the Chozo Robots in Ferenia and Ghavoran, Escue, Golzuna, Experiment No. Z-57, and the Red Chozo Soldier in Artaria.
