May Ross is the daughter of Spider-Boy and Insect Queen from an alternate future. Inheriting a combination of her parents' powers, May decided to carry on her family tradition of being a superhero by becoming Spider-Lass.
Spider-Lass shares several of the same powers as her father, such as superhuman strength and limited invulnerability.
Similar to her mother, Spider-Lass can mimic the powers of any kind of spider, such as:
- The leaping ability of a jumping spider
- The night vision of a wolf spider
- The camouflage ability of a whitebranded crab spider
- The web spinning ability of an orb weaver
