Shadow the Hedgehog was created about 50 years ago by Gerald Robotnik, Eggman's grandfather, which means chronologically he is over 50 years old
. However, Shadow was kept in cryogenic stasis for most of that time, which means he did not age physically during that period
. Because of this suspended animation, his physical appearance remains that of a teenager, around 15 to 20 years old, often considered about 16 or 17 years old biologically
. In summary:
- Chronological age (time since creation): approximately 50+ years.
- Physical/biological age (appearance and body): about 15-20 years old, commonly accepted as 16.
- Psychological age (mental maturity): similar to his physical age, around mid-teens.
- Immortality: Shadow does not age due to being an immortal, artificially created being kept in stasis
Thus, while Shadow is technically over 50 years old, he remains physically and mentally a teenager due to his immortal nature and cryogenic sleep.
