He'll just be standing in place, but he still has really slight movements when you pause the game. It's a lot less noticeable, but neither does Sonic.You merely pressing the pause button is not enough to freeze him in place.
In the PS 360 version, if you pause the game in one of the hubs, everything freezes in place except for Chip.Sonic the Werehog can stretch because his blood has been replaced by magma.One could argue that "Negative" Chaos Energy does exist, in the form of residual darkness from the Emeralds being used with dark emotions behind them (Shadow's early uses of them, fueled by anger and darkness, other ancient uses, Chaos itself using them in its tainted rage, etc).Chaos Energy is neutral, its effect just varies depending on the emotions you use to "channel" it. That was just a myth that stemmed from a weird mistranslation in Sonic Adventure. There is no such thing as negative Chaos Energy to begin with.Since Dark Gaia is active only in the dark, Sonic would have the same restriction. Sonic was transformed into the Werehog via a combination of both the negative energy of the Chaos Emeralds and Dark Gaia's force.Sonic isn't a Werehog at all, he's simply becoming one with Chaos. Chaos gets these same abilities when absorbing negative energies from the Chaos Emeralds. When Sonic absorbs the negative energies of the Chaos Emeralds, he gains stretchy limbs, super strength, a loss of speed (but retains his aerial agility), his attacks glow, and he gets a shark-like mouth of teeth. Actually, I thought of a better way to explain this.Didn't lose traits?!? The Werehog is noticeably slower than Sonic's default form, and his vector-manipulation abilities are modified - he loses his signature Jump Dash/Homing Attack and gains a Double Jump instead.He already had hair and lungs and genitals and stamina. Because werehog only made him gain traits, not lose them.Following the earlier would make ever more fridge logic on how he breathe on land, and have fur. If you're wondering how he retains his mind, think Kingdom Hearts. So, with that logic, his body was rather possessed by Dark Gaia, hence why the form only appears at night, has the ability to stretch arms (I've seen the other creatures do it), and since he's an anthropomorphic creature, it can pretty much justify why it affected him differently than the humans affected by it. It's rather that during the blast that woke up Dark Gaia, part of the Eldritch Abomination shot back up to the satellite and infected Sonic. Would've worked, if not for the fact that the Werehog isn't the result of the negative energies of the Emeralds.Chaos transforms into sea creatures when exposed to the NEGATIVE energy of the Chaos emeralds, why shouldn't Sonic also? - Not a troper, but was sitting in front of a fridge. His body, nose in particular, takes the shape of a shark and his arms can flail about like octopus tentacles. Then it occured to me when replaying Sonic Battle: he's not a wolf at all, he's a sea creature. I was always confused as to why exactly the Werehog looks so odd, and why he's able to stretch his arms.
