Sure, here's a step-by-step guide to drawing Goku from the popular anime series "Dragon Ball":


Step 1: Draw a circle for Goku's head and add two curved lines intersecting in the middle for his facial guidelines.


Step 2: Draw Goku's eyes along the upper part of the horizontal guideline. Each eye is an elongated shape with a smaller circle inside for the pupils. Add his eyebrows slightly above the eyes.


Step 3: Below the eyes, draw a small, simple nose, and then draw his smiling mouth slightly below the nose.


Step 4: Draw Goku's spiky hair. Start by drawing three large upward-pointing spikes in the middle of his head. Then, add two more spikes on each side. The hair should be bold and angular.


Step 5: Draw Goku's neck and shoulders by adding two slightly curved lines extending down from the head. 


Step 6: Outline Goku's muscular upper body by adding his chest and torso. Draw his gi (karate uniform) with a V-shaped collar and a belt tied around his waist.


Step 7: Draw Goku's arms. His biceps should be well-defined. Add his gloves and sleeves.


Step 8: Draw Goku's legs. Begin with the thighs and then draw his shins and feet. Add the boots at the bottom.


Step 9: Add details like the symbol on Goku's gi and the wristbands on his arms.


Step 10: Erase any unnecessary guidelines and lines, then review your final drawing with ink or darker lines.


Step 11: Color your Goku drawing. His gi is usually orange or blue, and his hair is black (or yellow in Super Saiyan form). Don't forget to add shading to make your drawing look more three-dimensional!

Remember, the drawing takes practice, so don't be discouraged if your first attempt isn't perfect. Keep refining your skills and experimenting with different poses and expressions to capture Goku's dynamic personality!
