Esmerelda Lobo is a mutant who could transform into a werewolf, like her brothers Carlos and Eduardo.
Even in human form, Esmerelda is faster and more agile than most people and can see in the dark better than most people can, but these abilities do not reach superhuman levels unless Lobo is in werewolf form.
Notes
The Spectacular Spider-Man #152 depict the Lobo Brothers living alone on the streets and they are never mentioned that, they have sister in they other appearances. However, despite this fact, Eduardo Lobo profile in The Official Handbook of the Marvel Universe #4, mentions that he has “unnamed sister”.
