Eggman likes to be annoying around in SRB2-Town, it seems :P In most of the cases, when there's a boss, it's Eggman's. So basically Eggman is in it. Remember that we annoy him as much as Sonic does. Which is great fun :)
New villians? Dunno >_> If I do, it'll be only for one series, due to the storyline, not a permanent one. The only permanent villian is Eggman, and that's all. And we make fun of him all the time :P
