Leo is an inhabitant of the Drake Isles who tells us about the suspicious abandoned laboratory of the Guild.
Profile[]
Appearance[]
Leo has middle-length orange hair tied into a low pony tail, green eyes and tanned skin, with a scar on his right arm. He wears the skull of a dragon on his head and a necklace likely made of dragon teeth. Besides this, he wears a ragged beige vest with no shirt underneath, dark brown fingerless gloves with golden rivets, and dark grey knee-length pants.
Personality[]
Even though he seems to be quite young, he's both brave and stubborn, as he doesn't desist on his attempts to enter the lab, even if he had to confront the Guild's guards or, eventually, face Amelie inside the abandoned lab. Little more is known, as he doesn't appear much during the story.
Story[]
In Nexomon: Extinction[]
Leo is a boy from the Drake Isles that had been trying to access the abandoned laboratory of the Guild located there. He suspected that they were hiding something dangerous in the building, and believed it was the reason behind the multiple dragon attacks that had been happening in it. To prove his suspicions, he attempted to access the lab repeatedly, until the Guild guards went to arrest him.

Vados appears at the abandoned lab
The player encounters him at that moment, and they're tasked with capturing him inside the airship heading to the isles. When they find Leo, he shares his suspicions with them, bribing them into joining his attempts to enter the lab.
From this point on, he travels with us, helping us to convince Lydia so she would let us go there. After proving our worth to her we enter the building, where she tells us about the creation of dragons years ago as well as the current intentions of Amelie, who is working on the creation of Vados. It is at this moment that Amelie appears at the lab and attacks us, eventually summoning Vados and commanding him to throw us out of the isles.
We manage to land safely at the Frozen Tundra thanks to the player's ability to control wind, and from that point we decide to split to try to find Amelie. We don't hear from Leo again after this point.
Post-game[]
He doesn't appear during the post-game.
Abyssals DLC[]
He appears in the Precursor Valley, where we can talk to him, but doesn’t take part in any specific events of the story line.
