Lightning Web

"Fires a spider net charged with electricity. Can be used to attack, wall jump or double jump."

- In-game text

Lightning Web (ライトニングウェブ) is the weapon that X obtains from defeating Web Spider in Mega Man X4. When equipped with this weapon, X will fire an electrically-charged web that stuns enemies. When fired, it travels a preset distance before it stays in place and acts like a wall for a short period of time - X can then use the Lightning Web to double-jump or wall-jump to reach new heights. When charged up, X fires a single web, which networks out to another eight, causing damage to multiple enemies.

This weapon is Split Mushroom's weakness and is also the weakness of Reaper Sigma's second form.
