Tidal Wave is a powerhouse, one of the largest Decepticons under Megatron's command. His power is backed up by a brain that doesn't exactly run at optimal speeds; he's not so much stupid as he is single-minded and easily frustrated, although his tendency to shout his own name repeatedly as a sort of battle cry doesn't do much to refute his reputation as a knucklehead. In battle he is merciless, an unyielding engine of destruction.

Tidal Wave was originally brought to Earth by the Decepticon strategist Thrust in an attempt to bolster the Decepticon forces so that they could obtain the Requiem Blaster. Thrust claimed Tidal Wave was a general that led Decepticon forces to a victory, an unsubstantiated claim that seems rather out of place considering Tidal Wave's... lack of grace. This was exemplified when Hot Shot and Blurr capsized the huge warship and sent it to the bottom of the deep. However, Tidal Wave quickly recovered and transformed into his massively powerful robot mode, quickly sending the Autobots scrambling for cover.
Pounding the Autobots with firepower, Thrust called out to Tidal Wave to initiate his party piece. Tidal Wave transformed and split into three component vehicle sections (which also somehow shrank in size), headed for Megatron and Powerlinked with him, forming a combination known as Burning Megatron. Megatron declared that "The Power is Mine!" (whatever he meant by that exactly is unknown....dork) before setting off in pursuit of Jet Optimus. Tidal Wave gave Megatron flight capability and an overwhelming amount of firepower, which kept Jet Optimus at bay long enough for Megatron to slice the connection point between Optimus Prime and Jetfire with the Star Saber.
After Starscream cracked and attacked Megatron, Tidal Wave was sent after him to Earth when the rogue Decepticon jet escaped their moon base with the Star Saber in his possession. The Autobots initially assumed both Decepticons were part of a combined attack, but eventually came to Starscream's assistance against Tidal Wave when the Decepticon shot him down. Hot Shot nailed Tidal Wave in the eye with his axle cannon, but the powerful Tidal Wave recovered quickly and caused problems for Jet Optimus, whom couldn't so much as scratch him. This prompted Starscream to toss the Star Saber to the Autobot leader, which he used to slice off one of Tidal Wave's chest guns and forced the Decepticon to retreat.
Tidal Wave was present at the meeting between the Autobots and Decepticons during the Unicron Battles in which the two sides formed a temporary truce, notably shaking hands with Jetfire.

After the end of the Unicron Battles, Tidal Wave loyally followed Galvatron's last request - that the Decepticons remain at peace with the Autobots. During the ten year period that followed, Tidal Wave somewhere along the line changed not only his color palette but his occupation - instead of being a warrior, he was now a guardian of the energon mines in the Sol system's asteroid belt.
Tidal Wave's post was one of the first targets of the Terrorcon hordes. After being attacked and abducted, he was brought to Scorponok and Alpha Quintesson's base of operations, where they convinced him to side with them by promising to revive Megatron, a deal which Tidal Wave eagerly agreed to. Although he clearly disliked Scorponok, he carried out orders in attacking other energon reserves run by the Autobots until Megatron returned. Following this, he continued raiding Autobot bases, only under Megatron's orders.
Tidal Wave would later show disdain for the madman Decepticon recruit Shockblast. During a battle on Cybertron, an energon tower collapsed on top of Tidal Wave due to a shot from Shockblast. Megatron called for a retreat and hauled Tidal Wave's damaged body back into space, where the giant Decepticon was reformatted into "Mirage".
Mirage traded his gigantic, hulking body for a smaller, sleeker, and speedier form. He also apparently gained an upgrade in intelligence, although he also started to buddy up with Demolishor and Snow Cat to form a comedy relief trio. He continued to serve Megatron throughout the war for energon.
When Galvatron flung himself into the energon sun to destroy Unicron's spark, Mirage loyally followed after him and seemingly ended his life.
Tidal Wave was little seen in the Armada comic from Dreamwave, appearing only in a panel or two in the final story.
In Energon, Tidal Wave was recruited by Scorponok, joining the Terrorcons. While he went on several raids and missions with the Terrorcons, it became clear to him that he wasn't the most respected of the team. Alpha Quintesson, however, saw something in him, and reformatted him into Mirage, noting as he did so that Scorponok had fallen out of Unicron's favor.
Tidal Wave, in his combined battleship mode, was stationed as a relay and refuel point off a small chain of islands in the Mid-Atlantic. The Autobots made their way inside him to take out the Decepticlone platoons inside and destroy him, but discovered that Tidal Wave wasn't merely a transport. They escaped just in time to avoid being crushed as Tidal Wave transformed into his titanic robot mode.
Tidal Wave walked around the island chain in the deep waters, unloading volleys of missiles, lasers, and the occasional Jet Laser on the tiny-by-comparison Autobots. Despite his impressive size, firepower, and nigh-impenetrable armor, the Autobots managed to do enough damage to Tidal Wave's one weak point -his face- to cause a chain reaction that caused multiple explosions inside him, sending him falling face-first to the ocean floor.
The Autobots were able to extract information from Tidal Wave's computer that the Decepticons' main base was located in Northern Alaska, but the information was planted there by Megatron to lead the Autobots into a trap.
