Pikachu
Pikachu's velocity capabilities, whilst respectable by the standards of biological organisms, operate in a fundamentally different register than dedicated speedsters. The electric mouse can run at speeds sufficient to evade predators in tall grass, execute the Quick Attack move with priority initiative, and generate static electricity through rapid cheek-pouch vibration. In the context of Pokemon battles, Pikachu possesses a base Speed stat of 90—above average, certainly, but far from the fastest specimens in its ecosystem.
The creature's most impressive velocity achievement involves electrical discharge rather than locomotion. Pikachu's signature Thunderbolt attack releases electricity at approximately 270,000 miles per hour—the speed of lightning itself. However, this represents the velocity of the attack rather than the attacker. Pikachu must remain stationary to channel such devastating discharges, creating a tactical distinction between offensive speed and movement speed that bears examination.
Sonic
Sonic the Hedgehog exists in a category of velocity that renders conventional measurement systems somewhat inadequate. His baseline running speed exceeds Mach 1 under casual conditions—a pace he maintains whilst collecting rings and dismantling robotic infrastructure. This supersonic capability represents his resting state rather than his maximum potential. When properly motivated, canonical evidence suggests Sonic can approach or exceed the speed of light itself.
The documentation for Sonic's supreme velocity is extensive. In Sonic Unleashed, he circumnavigates the planet in seconds. Multiple game manuals explicitly state light-speed capability. His transformation into Super Sonic multiplies these already incomprehensible velocities by factors that mathematics strains to accommodate. Sonic has outrun black holes—gravitational phenomena from which light cannot escape—suggesting his maximum speed operates entirely outside conventional physical law.
