Canonical Comic Speed Feats

The Flash (Wally West) • IMMEASURABLE

Outrunning Instantaneous Cosmic Teleportation

Calculated Velocity: Trans-Time / Immeasurable (Infinite)
Citation:
The Flash (Vol. 2) #138 (1998)

By borrowing the collective kinetic momentum of planet Earth and the alien Krakkl, Wally West crosses the universe faster than instantaneous technological teleportation, arriving before the instant occurred.

Distance & Timeframe: Billions of light-years across the known universe in Instantaneous (0 seconds / Negative Planck Time)
The Flash (Barry Allen) • MASSIVELY-FTL

Evacuating 532,000 Citizens from a Nuclear Detonation

Calculated Velocity: 3.71 × 10¹⁴ m/s (13,000,000× Speed of Light (c))
Citation:
JLA #89 (2003)

A 500-kiloton warhead detonates in Chongjin, North Korea. In 0.00001 microseconds, Flash carries 532,000 people 35 miles away to safety, carrying two at a time.

Distance & Timeframe: Carrying 1-2 people at a time 35 miles away (total distance: ~35 million miles) in 0.00001 microseconds (10 picoseconds)
Superman (Kal-El) • MASSIVELY-FTL

Interstellar Trans-Solar Cruise to Earth

Calculated Velocity: 3.94 × 10¹² m/s (13,149× Speed of Light (c))
Citation:
Action Comics #273 & DC One Million

Superman detects distress back on Earth while situated in the Vega star system and flies back across interstellar space in single-digit minutes.

Distance & Timeframe: 25 Light-Years (from Vega star system) in Under 10 minutes
Quicksilver (Pietro Maximoff) • FTL

Outrunning Electromagnetic Radio Waves

Calculated Velocity: 3.0 × 10⁸ m/s (1.0× Speed of Light (c))
Citation:
X-Factor (Vol. 1) #71

Pietro races across urban avenues to disconnect an electromagnetic trigger before radio waves traveling at lightspeed can transmit the detonation signal.

Distance & Timeframe: Running across several city blocks in Intercepting a radio broadcast signal before it connects
Spider-Man (Peter Parker) • SUPERSONIC

Point-Blank High-Caliber Sniper Evade

Calculated Velocity: 1,440 m/s (0.0000048× c)
Citation:
The Amazing Spider-Man #540

Spider-Sense warns Peter before the trigger pull, allowing his superhuman reflexes to twist his torso and dodge a Mach 4 high-velocity sniper round from inches away.

Distance & Timeframe: Bullet traveling 3 feet away at 3,200 fps in 0.0009 seconds (0.9 milliseconds)
Batman (Bruce Wayne) • SUBSONIC

Automatic Aim-Deflection & Crossfire Weave

Calculated Velocity: 120 m/s (0.0000004× c)
Citation:
Detective Comics #800

Batman tracks barrel trajectory and muzzle flash, utilizing predictive aim deflection to weave between continuous automatic rifle fire.

Distance & Timeframe: Weaving through a 30-round automatic burst at 20 feet in 0.05 seconds reaction time
