Dragon Ball Timeline Milestones

Dragon Ball Zero

Beginning - Characters are under sonic speeds, except for Regina.

The United Government saga - Regina's abilities mark the uppermost range of human potential.

Dragon Ball X

Lord Jarek battle - The majority of fighters can withstand nuclear blasts with little harm.

The Super Seventeen Battle - Seventeen and Eighteen are the first fighters to break the speed of light in combat. Also, all characters can survive planet-busting explosions. This also marks the limit of Namekians.

Dragon Ball NG

Beginning - All characters can move faster than light, with Seventeen reaching speeds of 1 parsec. This also marks the upper limit for Saiyans still living on Bejita-sei.

End - All characters can now go 20 times the speed of light, and can tank

Dragon Ball Wars

All characters can survive the detonation of a supernova, meaning that they have multi-Solar System level durability. Most characters are now moving at 100 times the speed of light.

Dragon Ball Aftermath

The strongest characters can cut brown dwarf stars with missed punches and can shatter neutron stars with repeated strikes. All characters can move Earth out of orbit by hand.
