Beginnings
Danny is the only nephew of Reed Richards with a speed power. Danny found out about his powers when he was 12 years old, and he is currently 17.

X-Men
He is apart of the X-Men (Earth-29876433). The story of how he got apart of the team is when he was homelessly walking down the sidewalk at age 15 and he saw the huge mansion and decided to explore. Professor X, who was waiting outside for the current X-Men, wondered what he was doing there and read his mind. He found out Danny had powers, and took him in as a mutant. He never left the X-Men since.
