I want to know how I can model Sonic the Hedgehog or Hector from Castlevania Curse of Darkness:confused: 
get a picture of your characters from different angles and extude away:)
i forgot to mention im a noob and need a little more detail
The popular answer is find the “create X” Button.
The realistic answer is to run through the Noob to Pro page here. The fact that you have no idea what extruding is means that you need to get antiquated with blender.
Of course, how simple! Just add Suzanne (Space bar>>Add>>Mesh>>Monkey) and then, in edit mode (TAB toggles Edit and Object mode) select vertices (press b and drag box, or press b twice and click with vertices inside circle) grab them (press g) and move them around (drag with mouse ) until they look like Sonic the Hedgehog! It would help having a front and side view of Sonic in the background, so use the View menu (Background image) to put it there. Easy.
Hayamo, it’s really bad form to double post here. Be patient. Like the sign in the printer’s office says: “You want it bad? You’ll get it. Bad.”
I’d suggest learn 3d theory, get really good at drawing, familiarize yourself with blender, get really GOOD at blender, model, animate, render, voice-over, and then package it off to a renderfarm.
u can try this modeling video (has 4 parts to it)
this is wat i did wen i modeled sonic. It may be an bad way to model but it got the job done
