Yeah, I was thinking of putting a 60 year old Kalama in here (compared to the point where his powers usually completely manifest, which is usually 200 to 230 years of age). So he'll just be getting pyrokinesis and an increase to strength beyond what his muscle density would give without mutation. His powers would begin manifesting about age 50 or so, so he'll have approximately a decade of manifestation, which isn't much considering he'd have over a century more before they completely manifest.
