Trevor

How to get it

Inside Don Swan's mansion (Mansion, Second Sea), at Kingdom of Rose, near the pool.

What he asks of you

Two conditions, and both count:

• Be Lv. 1000 or higher. Below that, he won't even talk to you.
• Give him a physical fruit worth 1,000,000 Beli or more.

Important method note: the fruit must be taken out of storage and present in your hotbar. A fruit stored in your inventory doesn't count - you have to unstore it before talking to him.

All his dialogue

What he says	What it means
Get out of here before I kill you.	You're not Lv. 1000 yet.
You seem strong. Are you here to join our organization?	You're Lv. 1000+ but you don't have a physical fruit in your hotbar.
Bring me an expensive Blox Fruit to prove yourself worthy of speaking to Swan.	He's asking you to give him a physical fruit worth 1,000,000 Beli or more.
Don't disappoint me.	He's giving you time to go get a physical fruit worth 1,000,000 Beli or more.
This is an excellent fruit, You may now speak to Swan.	The fruit is the right value: he takes it and Don Swan's room opens.
This fruit is garbage, but I'll take it anyways.	The fruit isn't worth enough: he takes it anyway, you lose your fruit and don't get access.
That was a nice fruit.	You already gave him a fruit. If you show him another one, he won't take it.

The cheap fruit trap

The key line is "This fruit is garbage, but I'll take it anyways" : if the fruit you give him is worth less than the threshold, Trevor takes it anyway without giving you anything in return. You leave with no fruit and no access.

The Fandom therefore recommends bringing him a Quake, one of the most common fruits above 1,000,000 Beli.

Good news once the deal is done: he won't extort you twice. After your first valid gift, he refuses all other fruits you show him.

Why he matters to your progression

• Defeating Don Swan is necessary to unlock the V3 stage of your Race.
• Trevor is a key part of accessing the Third Sea, since you must have defeated Don Swan to go there.
• In other words, without getting past him, your progression is stuck at the Second Sea.

An inconsistency acknowledged by the source

The Fandom itself points out a contradiction: Trevor demands a fruit worth 1,000,000 Beli, but he accepts the Meme, a fruit that costs only 1 Beli.

The hypothesis offered on the page is that the displayed threshold isn't the real criteria: in practice, Trevor would only accept fruits with Legendary and Mythical rarity. Take this as a deduction from the source, not as a rule confirmed by the game.
