Serpent GearSerpent Gear (サーペント・ギア) is the Mechaniloid spat out by GearBank in an attempt to run over Zero. They drop parts when defeated.
GearBank is a simple sub boss, but the amount of health it has can drag out the fight. With proper timing and accuracy, one can hit all the hatches simultaneously with a charged Z-Saber, inflicting massive damage to it. The EX Skills Burning Shot and Time Stopper are also good choices too multi hit. The SerpentGears are easy to defeat, but become faster one the hatches lose more health, making them a nuisance. All the saber skills can wipe them out quickly, so this is recommended to focus on GearBank itself.
