Tornado Fang can also be used to break some walls in the game, such as the ice blocks in Blizzard Buffalo's stage and the wall hiding the X-Buster upgrade in Neon Tiger's stage. This is abused several times throughout the run. Tornado Fang has another trick, which is that whenever an enemy is drilled by it, it stops doing collision checks for 15 frames, allowing X to completely dash through an enemy unharmed if it's hit by Tornado Fang. Usually though, this takes too long to kill something with it.
The drills don't do much damage, but keep drilling enemies every 30 frames (half second) for several hits. Pressing shoot quickly again releases another two drills in a spread fashion.
