While Super Mario RPG's story mode bosses don't offer too much of a challenge according to our review, a secret, iconic boss fight has made its return for the remake. In this guide, we'll tell you everything you need to know about Culex.

Culex was added to serve as a node to Square's Final Fantasy franchise. He is perplexed by Mario's 3D appearance, arriving in his world to fight in the name of the Dark Mage of Vanda.

He is beyond a shadow of a doubt the strongest boss in Super Mario RPG so if you want to go in prepared, better read this guide!

Where to find Culex in Super Mario RPG

It's worth noting that you can fight Culex the first time (more on that later) even before you finish the main story of Super Mario RPG. It is somewhat not recommended due to him being the hardest foe in the game, but it might be worth going under-levelled if you want an extra challenge.

Finding him is relatively easy. When you arrive at Moleville, you'll find an NPC sitting outside a house asking if you want to trade fireworks for a Shiny Stone, you need this to find Culex.

Do you see that house in the picture above? That's where you'll find the fireworks, but it won't come cheap, you need to purchase them for 500 coins.

Once you do that, trade them for the Shiny Stone and head to Monstro Town. If you've been here before you might have already noticed a strange locked black door. If not, you'll find the door right next to the item shop in this town.
