SP Ultra Instinct -Sign- Goku (Purple)

Because of the Ultra Instinct gauge, -sign- doesn't need to worry about a lot of minor neutral game annoyances that other characters do. At close range he's entirely invincible while the gauge is active, as he can interrupt the attacks he cannot automatically dodge very easily. 

It's brutal at midrange. Enemy Fighters need to either approach themselves or wait out the gauge's timer, because nothing they do can catch him off-guard that he can't automatically dodge. Simply floating forwards and backwards with -sign- puts up a near impenetrable defensive wall. 

Seeing as foes are incentivized to approach with tap attacks or fire tap shots to deplete it, Ultra Instinct Goku has a very easy time gaining priority in combat, typically with a well-timed blast arts. This gauge defines the way he functions and any player seeking to master UI Goku must understand its strengths and weaknesses thoroughly. 

After it activates, Goku is not at a frame advantage, so it's very possible for a foe to perfect vanish an attack he throws out if he's too hasty with his punish. The gauge cannot protect him during recovery animations. Simply put, this is an aspect of his kit that makes him better than other fighters mechanically. He has the best neutral coverage in the game. 

SP Ultra Instinct -sign- Goku PUR is far from all-flash, no substance. His Combo game rivals the best of the best thanks to his unique abilities, which give him periodic injections of Ki and Inflicted Damage Buffs the longer he spends on the field, 3 and 8 Timer Counts for 30 Ki and 20/30% Damage Inflicted respectively.

Not only are these requirements child's play for a fighter with the Instinct Gauge, these effects' mercurial activations allow him to seamlessly extend combos after switching in on the offensive.

Speaking of offenses, his base stats are nothing to scoff at, especially when they're augmented by a constant 60% Inflicted Damage Buff, a 50% Ki Recovery Buff, and a permanent 5 Ki Cost Discount for Strike and Blast Arts. 

Goku's explosive Damage potential is owed to his specialty arts cards, those being his Special Move, Special Arts, and Ultimate Arts. His Special Move's Massive Damage Multiplier and Added Damage Bonus on activation are great by themselves, but the fact that it recovers 50% of his Instinct Gauge is what really puts it over the top as a combo finisher. 

His Special Arts is arguably the most powerful one in the entire game, sporting 10% Health Recovery, 40 Ki Recovery, a 20% Damage Inflicted Buff, and +1 Card Draw Speed on hit. The move is hardly difficult to make contact with either - it's a unique radius attack that hits all foes in close or mid-range, and its fast start-up speed makes it very difficult to react to - unlike other special arts of this type. 

Like many brokenly powerful characters, Goku's best offensive trick is his Main Ability, which draws a brutal Ultimate Arts card that sports the first Super-Massive Damage multiplier (It's the same numerical multiplier as Supreme though, so SP SSGSS Vegito BLU is very annoyed at UI Goku pretending he's special), and it even cancels all enemy Attribute Upgrades. 

This Main Ability doesn't just close out games, it completely shuts down enemy Crisis Fighters on command, letting it secure victory before Goku's foes have a chance to forfeit out of the Legendary Finish.
