Turn 2:
Ryu: Super Combo
Nina: Defend or Heal
Garr: Defend or Heal
Turn 3 - ??: Use Wisdom fruit on Ryu when necessary, and multi-vitamins when his health drops low. (Berserker should not kill you instantly if your defence is high enough, and if normal laser attack doesn't kill you, you're safe.)
Near end when Berserker has about 2000 hp left: He will use Berserk.
Then use:
Ryu: Super combo
Nina: Myollnir
Garr: Attack
If he lives, pray he hits Ryu (Kaiser) but hopefully, you should kill him before he gets the chance. Just have patience.

Another way to defeat the Berserker
Note: Most of the equipment listed is essential to protecting against the Berseker's attacks.
Berserker: Approx. 12,000 HP
Characters-
Ryu: Level 48 or higher
Weapon / Armor: Dragon Blade, Dragon Armor, Dragon Helm, Dragon Shield
Accessories: Soul Gem, Speed Boots
Skills: None
Genes: Force, Flame, Defender
Rei: Level 45 or higher
Weapon / Armor: Piercing Edge, Life Armor, Aries Gloves, Sun Mask
Accessories: Soul Gem, Lion's Belt
Skills: Weretiger, Speed
Garr: Level 41 or higher
Weapon / Armor: Dragon Spear, Royal Armor, Giant Shield,
Accessories: Soul Gem, Ring of Fire
Skills: Influence
Recommended items: 3 or more Wisdom Fruits, 3 spare Soul Gems, As many Multivitamins and Ammonias as possible
Tactics-
Turn 1:
Ryu: Accession (Force + Flame + Defender)
Rei: Cast Speed on Garr
Garr: Defend
Turn 2:
Ryu: Focus
Rei: Weretiger
Garr: Influence on Berserker
This plan has Ryu in Warrior form attacking the berserker while Rei in his weretiger form also attacks the berserker. Rei will not attack your party as long as Garr uses influence on the berserker every turn. You don't acually have to use weretiger as part of the plan, but it kills the berserker faster so he won't get a chance to get many attacks in before he's gone.
Turn 3:
Ryu: Aura
Rei: (Weretiger) Attack
Garr: Influence on Berserker
Turn 4-??: Have Ryu use Focus to up his attack then use Aura. Keep doing: Focus then Aura then Focus then Aura. He doing that until he's dead. Have Garr heal or revive anyonw who's hurt. You won't need to worry about flame attacks because of the Dragon Armor on Ryu, the Sun Mask on Rei, and the Ring of Fire on Garr, but you will need to cure physical attacks with Multivitamins. If Garr heals instead of Influence, don't worry. Influence lasts for a few turn and then wears off.
Keep doing this until he is dead. Good Luck!
