From the Super Mario Wiki
A Thunder Rage is an item in the Paper Mario series.
It first appears in Paper Mario. It deals five damage to all enemies on-screen, and acts like a stronger version of Thunder Bolt, an item that hurts only one enemy. The Thunder Rage appears to be upside down, as opposed to its upright position in later Paper Mario games.
It reappears in Paper Mario: The Thousand-Year Door. There, it even has a little chance of stunning enemies. It can also be cooked by mixing a Shooting Star with a Point Swap. However, if used on lightning related enemies such as Ruff Puffs, they will gain HP.
When used in Super Paper Mario, the player must first shake the Wii Remote to gain power. After that, lightning will strike on-screen enemies, damaging them. It can be cooked to make an Electro Pop
In volume 26 of Super Mario-Kun one Yoshi in the Fearsome 5 uses a Thunder Rage to defeat a White Magikoopa.
