Grenado

The Grenado is one of Brainstorm's inventions. On detonation it produces a miniature tornado which can cause damage to a targets within a surprisingly small radius but leave more distant targets unharmed.

Fiction

IDW Generation 1 continuity

As Braimstorm was standing prepared to shoot an uncompleted Megatron, a grenado materialized at his feet, having been sent through time ahead of Rodimus's team. On detonation it managed to take out Brainstorm, though he was later able torecover enough to stand and aim his gun at Megatron again. Elegant Chaos Part 3: Predestination: An Expert's Guide

Note

• The Grenado is presumably the mortal enemy of the Tornadon't.
