Step 20: Use the angled line and small circle on the left as guides to draw the other arm the same way as the first. Draw a curved line at the top of the line for the sleeve. Don't overlap the chest. Darken the middle section of the guide for the arm. Draw a second line nest to it to make Robin's arm thicker. Draw a blocky shape above the small circle for the top part of the glove. Draw the hand along the edge of the initial circle. Add a small, curved shape at the bottom for the folded finger.
Step 21: Use the long line on the right as a guide to draw the first leg. Follow the path of the guide and draw the shape of the leg around it. The top and bottom of the leg should be wide. The shape should come inward near the middle for the knee. Draw a half-circle inside the arc guide at the bottom for the tip of Robin's boot. Darken the bottom part of the arc for the boot's sole. Add a couple more lines for the heel and the top of the boot.
Step 22: Use the line on the left as a guide to draw the other leg the same way. Follow the path of the guide and draw the shape of the leg around it. Draw the area near the middle of the shape inward for the knee. Make the bottom very wide. Draw a half-circle inside the arc at the bottom for the boot's tip. Darken the rest of the arc for the sole. Draw a line near the back for the heel and a line below the knee for the top of Robin's boot.
Step 23: Draw a series of lines in the space between the arms and legs for the cape behind the body. The shape should be similar to a big rectangle behind Robin's body. Don't overlap the limbs.
Step 24: Go over the final sketch lines with a pen, marker or any other type of permanent ink. Take your time and be careful when you ink to avoid any accidents. After the ink dries, get rid of every pencil mark with an eraser for a cleaner drawing.
Final Step: Color your Teen Titans Go! character drawing using colored pencils, markers or crayons! Use peach for the skin. Use black for the hair, the mask, the inside of the emblem, the neck, the edge of the cape and the tops of the boots. Use green for Robin's sleeves, gloves, and pants. Use yellow for the collar, the R, the belt and the inside of the cape. Use red for the shirt. Use gray for the boots. Don't forget to pause the video to draw at your own pace.
