Every Dragon Ball fan remembers the iconic Ultra Instinct Goku fight with Jiren from anime, which also prominently appears in Sparking Zero as a boss fight. While playing as Goku can be easier in most experiences, the Jiren side of things is challenging, since you fight Ultra Instinct Goku.
It almost mirrors the Great Ape Vegeta in difficulty. So, here are some tips to make the Ultra Instinct Goku fight a little easier if you are having trouble defeating the boss, even after using any number of abilities.
How to defeat the Ultra Instinct Goku in Dragon Ball Sparking Zero
Play extremely safe
Play safe until you encounter Ultra Instinct Goku. Keep your distance, use ranged attacks, dodge more, and keep your defenses up.

You’ll be facing multiple enemies, including Android 17, Freiza, and Vegeta, before you get to Ultra Instinct Goku, so conserve as much health as you can.
Utilize your Sparking Meter
Sparking Meter is extremely important in this boss fight because Goku, in this form, makes it hard to land any attacks. Ultra Instinct Goku dodges most head-on attacks during the boss fight, making it tougher to deal with him.

Hence, use Sparking attacks and ki charges whenever possible. Take any opportunity to charge up during the boss fight, as you’ll get really tight windows to do that.
Use the Meditation technique
Jiren has access to a handy tool called Meditation, which allows him to refill one whole health bar when used. Using meditation requires Jiren to have a skill count of four. While you can’t use it frequently, it is a vital kit to use occasionally to keep your health bar intact.
Be careful; Jiren loses Meditation when he enters his complete power form. So, before that happens, use Meditation whenever you see your health low. Otherwise, you’ll probably have a lower health bar while dealing with Ultra Instinct Goku.
If you follow these tips to the point, you’ll have no trouble defeating Ultra Instinct Goku. Of course, it is still a challenging and fun boss fight, but these tips should make it a little easier.
