Wepwawet was the only hero to have upgrades that increase the DPS of exactly one other hero until patch 1.0e10. This may be a way to balance out the fact that those heroes do not have any self-DPS upgrades (with Betty having only global DPS upgrades, and Midas having only Gold-related upgrades).
Wepwawet was the most expensive hero and highest level need character before the 1.0e3 patch.
Wepwawet was the first hero since Dread Knight who doesn't use the typical "Level 10-25-50-100" Upgrade requirements.
Wepwawet is the only hero whose upgrades have no description.
Wepwawet is an Egyptian deity associated with war (as a scout), then death opening the way to the afterlife.
He is the last of five new heroes introduced with the 0.24 Patch.
Most people agree that this is the hero when the game gets difficult, or when the zone progression gets slower. This also applied on Tsuchi and Skogur.
