Who's the fastest/speediest digimon?

[Casper]

A teleporting digimon technically would be the fastest as speed is measured by distance over time. Renamons teleportation is almost instantaneous, however I doubt she can use it over a long distance, she would likely use a series of teleports to move long distances. Both digimon move about light speed, but renamon hiys full speed at the snap of a finger, I imagine reaching light speed through muscle power would take a long time. Likely renamon would win in a race over a short distance due to her ability to reach to speed from the word go. Over a longer distance however my money would have to be on rinkmon, hes just running, renamon has to constantly find her next warp spot, this would probably slow her down.

Though rinkmon could never achieve light speed due to the lorentz factor, as his mass increased he would need more energy to go faster, as he did thishis mass would further increase. He would need an infite amount of energy. Which is why he travels sub lightspeed and why renamon would have to as well, even if she is teleporting somethings gotta move.

Oh and GMSG lightspeed equals a change in mass not weight. I doubt we would see much of a physical change.

Wow thats a good way of explainig what will hapen if you went as fast as the speed of light and i think your right rinkmon would beat anyone with enough space to gather enough momentum but it its a short race against somone like renamon she would win because as you said shw will instatnaiously reach her maximum speeed in a flash while rink mon needs to gather momentum first which slows him down (also if you look at rinkmon you can tell he was buitl for speed
