XS-03 Apollo is a post-Moon Lord boss from Terraria that comes for a battle with a group of Exo Mechs, blocking the player's way and attacking fiercely. It is considered one of the most challenging bosses in the Calamity Mod that fires Large Volatile Plasma Blasts at the player in the first phase, and can choose its next weapon for the second phase. However, if a player is strong enough to endure all the attacks, they can obtain The Atom Splitter, a javelin that deals about 70% damage when used. Bring that fierce, fighting spirit of the game right to your screen with this fanart Terraria XS-03 Apollo and The Atom Splitter cursor!
