The Longest Three Hours

You will first face three Saibamen. They can interrupt your combos with attacks from behind and use Ki blasts, Assault Claw (a melee charge after Ki charging), and Bio Blaster (large Ki blasts).

Utilize Yamcha as a support character. His Super Attack is the Kamehameha.

Use Vanish Attack or Burst to knock enemies away if overwhelmed.

Focus on defeating one Saibamen at a time to reduce pressure.

After defeating the Saibamen, watch the following scenes.

Prepare to battle Nappa. You will have Tien and Krillin as support characters.

Tien's Super Attacks are Dodon Ray and Tri-Beam. Krillin's Super Attacks are Kamehameha and Solar Flare, which can stun all enemies.

Pay attention to the Z-Combo meter in the bottom right. When filled for all support characters, you can initiate a Z-Combo, a cinematic attack.

Nappa's primary attack is Arm Breaker (melee). His Super Attack is Giant Storm, indicated by a large circle on the ground; exit this area quickly to avoid damage.

Nappa is level 11, so ensure your character is of a similar level to deal full damage.

After dealing enough damage to Nappa, the fight ends. Watch the subsequent scenes.

You will have a chance to explore the region while waiting for Goku. Random encounters may now include Saibamen.

Speak to Krillin or Piccolo to continue the story.

Choose the option to "continue waiting for Goku" to initiate the next battle.

You will face Nappa again, this time with Piccolo and Krillin as support.

Nappa has new Super Attacks: Bomber DX (exploding energy ball) and Blazing Storm (a wall of explosions). He still uses Arm Breaker and Giant Storm.

When Nappa gains an aura, he has super armor and is impervious to knockback, though Solar Flare can still stun him.

If Nappa is above you in melee range, he can use Sonic Storm to knock you down.

Dodge Blazing Storm by moving forwards or backwards, not side-to-side.
