Lightning Grenade is one of Blanka's Special Attacks, introduced in Ultra Street Fighter IV's OMEGA Mode.
Description
Lightning Grenade being used against Ryu.
The attack is a more powerful version of the EX Electric Thunder that it replaces (and is executed the same way), but uses 2 bars of the Super Combo Gauge instead of 1. Blanka will perform a small forward hop (during which he is invincible) and surrounds himself with electricity.
