Model shows in "Game" preview, but not in actual game

Right now, I’m just laying out a design for a game. The main character will show in the “Game” preview window in Unity, but not in the game when built and ran. Example: I have no idea what's causing this.

Does anyone know how to fix this?

wild stab in the dark but you may have the tag editor only set on it.

Unity imported the nonexistant animations from the .blend file. I set it to not import animations on the file, and it was fixed.
