Tri-Thunder, known as Triad Thunder (トライアードサンダー Toraiādo Sandā) in Japan, is the Special Weapon obtained from Volt Catfish in Mega Man Xtreme 2.

This version of Triad Thunder works in a different way from its appearance in Mega Man X3. When used by X, he shoots three electric arcs which spread out in three directions. When charged, X raises his arms and large balls of electricity are shot in random directions from where he stands. It should be noted that when using Tri-Thunder, if the player tries to charge this weapon by holding the B Button from the subscreen or by shifting though other Special Weapons, the uncharged version will automatically fire first, wasting Weapon Energy. If the player wishes to simply use only the charged version of Tri-Thunder without firing a normal shot first, the player must deliberately make X contact an enemy before holding the B Button, or, when fighting a boss, by equipping the desired weapon first, then holding the B Button down as the boss's health fills up. Alternatively, the player can also switch to a different Special Weapon, pressing and holding the B Button while X is present on the screen, and while still holding the B Button down, the player can open the subscreen and select Tri-Thunder; once the subscreen is closed, X will begin to charge up Tri-Thunder without wasting any Weapon Energy.

Zero can also obtain Tri-Thunder from Volt Catfish, but to accomplish this, the player must be playing on Extreme Mode, and Zero must be the character that deals the final blow on Catfish, otherwise he will not be able to obtain it. When used by Zero, he punches the ground, sending out many balls of electricity in a V-shaped manner. This move can only be activated when selected from the subscreen, and Zero must be on the ground when performing it, otherwise nothing will happen.

Both versions of Tri-Thunder are a primary weakness for Launch Octopus, and, in Boss Attack Mode, Armored Armadillo.
