She was arguably the leader of the Deadpool Corps, or at very least co-leader with 616-Deadpool.
She was a member of the X-Women, an all female sub-group of the X-Men.

She has scars but they were later removed.
Wanda Wilson, alongside Deadpool, Kidpool, Headpool, Dogpool, and Major Deadpool is an original member of the inter-dimensional Deadpool Corps.
In the final battle with the Evil Deadpool Corps, Wanda was tragically killed, leaving 616-Deadpool as the team's undisputed leader. Only 616-Deadpool survived, leaving him, and a few members of the Evil Deadpool Corps the only Deadpools left in the multi-verse.
