Tatsuya is generally one of the best assists when it comes to damage. His main use in Ignition is his 6S which increases damage of combos and the player’s next CA. In Vanilla the Climax Support wasn’t present and the opponent had to be grounded to land 6S. The most notable example is GO1’s team of Shana/Tatsuya. Besides 6S, Tatsuya’s 5S is a good way to stop the opponent from pressing buttons like most counter assists do. Triggering him should be especially feared when your opponent has a cmd grab since you actually can’t do anything about it besides Escape blast. Most players use him for his 6S since that’s his most important tool so if you’re looking for big damage he is definitely your go-to.
6S increases damage output for combos
Characters with cmd grabs can get it for free with 5S being triggered
Can give explosive damage to every character
Not a good assist in neutral
Tatsuya appears in front of the player with two CADs and creates a defensive field. If attacked his counter will trigger and will immobilize the opponent for a few seconds. When immobilized the opponent can only Escape Blast, block, and tech throws.
Tatsuya uses his CAD to lock the opponent in place.
Unique Skill: If the opponent gets hit or blocks, the next Climax Art from the player will receive a Climax Support buff increasing the damage of the CA. As the move causes no proration it's an excellent combo extender.
