The Mighty Oak is the first boss encountered in Epic Battle Fantasy 4. He is the guardian of Ashwood Forest, with his power over nature protecting much of the area from the effects of the cataclysmic meteorite impact that ravaged the rest of the forest.

Although he acts as a boss for the heroes to fight, the Mighty Oak is not a hostile creature. Instead, he serves to test the party's strength to determine whether or not they can withstand the trials beyond the forest. Once he is defeated by the party, he lends his strength to them as one of Anna's unique Limit Breaks.


The Mighty Oak is a huge humanoid golem mainly made of wood and bark. He also features some metal parts, likely to improve his durability and combat capabilities. Two round holes in the bark serve as Oak's eyes, and his lower jaw and feet are made of steel. He has a shield mounted on his left arm and a big metal pin on his right arm. Both arms also have large chains hidden within them, enabling them to be launched great distances. The Mighty Oak's head and shoulders also bear a few small twigs.

The Mighty Oak bears physical resemblance to both Golems and Wooden Idols. It is highly possible that the Mighty Oak was constructed and animated in the same way as a normal Wooden Idol, being a mass of wood brought to life by magic.


The Mighty Oak mainly relies on his great physical strength in combat, delivering powerful stomps and slams with his titanic body. His arms can extend on heavy chains to strike his foes from a distance, and he can jump surprisingly high to crush enemies or create damaging quakes. His control the forest allows him to perform powerful Earth-based skills (such as Lumber and Gaia Blossom) and raise his own stats, as well as summon the native creatures to his aid.

As the first boss in the game, Mighty Oak should not pose much of a challenge, unless you are playing on Epic, in which the Mighty Oak may be the hardest boss in the entire game. The Mighty Oak uses only Earth and non-elemental attacks, so equips that boost Earth resistance are the best choice for defence, otherwise equips that provide the highest stat bonus should be used. Player should equip weapons of either Fire or Poison element as this are the Oak's weaknesses. Anna may use her starting Fairy Bow or get the Crimson Dragon bow from Greenwood Village equip shop for 3000 gold. Matt does not have any weapons of these elements yet, but he should take Heaven's Gate as Silver Blade's Wind element is resisted by the Mighty Oak. Natalie's Flameheart is the best offensive choice, though the Crystal Staff proves very useful (especially on Hard/Epic) as it is able to Dispel the Oak's massive attack buff.

Limit Break

"Go, Mighty Oak, show these chumps to never underestimate the power of the forest!"
―Anna, Epic Battle Fantasy 4

After the players have beaten the forest guardian and proved themselves worthy, Mighty Oak joins the party as one of Anna's unique Limit Breaks. It will instantly appear on her skills list, already on the first level. Upon casting the skill the Mighty Oak will charge into the battle and unleash a series of blows onto the enemy team, ending with a jump to smash them, and then jump back off the battle, dealing massive Earth elemental damage in the process.

  • The Mighty Oak may be inspired by the "Great Deku Trees" from The Legend of Zelda series.
  • The Mighty Oak is one of the few enemies in the EBF series who is not killed in battle with the heroes. When his HP is depleted, Anna comments that he isn't actually injured, just knocked onto his back (and unable to get up, due to his bulk).
