The paparazzi are a group a photographers who relentlessly stalk anyone of famous note, usually Sonic the Hedgehog or anyone associated with him. Their camera flashes can be spotted during some of the most inappropriate or embarrassing moments and most of their work tends to end up in the tabloids.
Rumor has it many of them have been trained in the ninja arts due to their inhuman stealth abilities. They also work with the most sophisticated technology; stealing or destroying their cameras doesn't mean anything if the images are digitally forwarded directly back to their computers after all.
