- Super strength
- Near invulnerability
- Limited shapeshifting
- Plant control
- Can absorb water to grow larger and stronger (because he has a hydrostatic skeleton)

Tall and rooty with two piercing green eyes, Hardwood has a mostly dark brown body with bright green muscle-like vines and bright blue water sacs scattered across his body.
Ben first used Hardwood in Episode 1 of Ben Watch Power to battle the alternate universe Ben and his minions to rescue Argit.
