Sonic
The Hedgehogidae velocity specimen represents perhaps the most concentrated embodiment of speed in entertainment history. Sonic's documented velocity reaches 767 miles per hour at baseline, with his signature spin dash generating centrifugal forces that would liquefy ordinary biological matter. His entire existence is predicated upon motion, his iconic red sneakers specifically designed by Dr. Ovi Kintobor to withstand friction that would incinerate conventional footwear.
Spongebob
The porous invertebrate's relationship with velocity exists in curious opposition to conventional physics. SpongeBob's documented attempts at speed typically result in catastrophic failure, most notably his fifteen-year inability to obtain a boating licence. His leg rotation during running sequences, whilst visually frenetic, produces minimal forward momentum. Yet one must acknowledge his metabolic efficiency: the creature generates maximum activity whilst remaining effectively stationary.
