Nate can copy abilities, but Sonic (really Rewrite technically from concept art and doodles) is the default,

He can also shapeshift, but likes to make it so there's a difference, here's how to tell

Hungry: has top hat or fur same color as Nate's shirt

MG4: 4 on shirt replaced with N

If he shapeshifted into other people's OCs/Sonas

Mono (@monochromemann ): white bow tie replaced with green bowtie and slight alterations

Oldkid (@BUPdy 's Roblox avatar/OC(?)): different eyes

If this post gets 10 likes I'll draw Nate taking the form of my friends on Gamejolt
