Hi Matias,
You can do a lot of different spins with the Tomahawk serve. They will all have some sidespin but you can vary whether you put backspin or topspin with it. You get backspin by coming under the ball a little and topspin by going over the top of the ball on contact.
You can also hit the ball with the back of the bat for the Reverse Tomahawk serve. experiment and see what you can come up with.
