Wendy (Edolas) is the Edolas counterpart to Earthland's Wendy Marvell. Unlike her shy counterpart, this version of Wendy is notably mature and confident—she's basically a completely different person personality-wise. Both share the same striking long blue hair, though based on appearance, Edolas Wendy appears to be in her late teens.
She first shows up at the Edolas Fairy Tail guild base, where she and Warren are the ones who clock that the girl Natsu brought along is literally Wendy herself. When the Fairy Hunters arrive at the guild, she's the one explaining the situation: thanks to the king's orders, Fairy Tail has been forced into operating as a Dark Guild.
What's interesting is that she's the only known Edolas counterpart with a noticeable age difference compared to her original. While most counterparts look basically identical, Wendy stands out.
Combat-wise, she fights with a pair of unnamed magical daggers, which sets her apart from her Earthland counterpart's magic-based approach.
