DG-42L

DG-42L is the train-car sub-boss of Slash Beast's stage in Mega Man X4.

Strategy
Its attacks consist of extending spikes to impale X or Zero and firing a series of energy spheres at X/Zero. If X has the Ultimate Armor on, or at least the right Arm Part, he can easily make short work of this sub-boss. Zero, on the other hand, will have to close in and destroy the spike with Z-Saber before it can spear him. Note that only the tips of the spikes seem to cause damage, not the shafts. The spike can be permanently destroyed by destroying the side of the train where the spikes emerge. The Frost Tower works best as it can destroy all the spikes and deal a considerable amount of damage.
