Just a big old upside down U shape for his big bald head
Draw some simple dots for eyes and a good curly shape for the nose
Then draw a sausage for the mouth and make it stripey for teeth
Make his eyebrows look all heroic by drawing one straight and one curved. You can also add a mouth-brow to emphasise his smile.
Don't forget a couple of circles either side for ears!
Add a circle and 2 wavy triangles to form a knot for starters
Then moving out from that, draw a bunch of wavy lines to give a good cape shape!
Draw a couple of lines coming from under the cape with some sausage shaped fingers. Have fun trying out a few different powerful poses!
Draw a big curved line for his good strong stomach! (Make sure to leave a little gap for the legs)
Add a couple of thick backwards L shapes to the bottom of the body. Draw some toes on the end with a little squiggle and a backwards C in the ankle.
Add a waist band with a curved line around the body and then add extra details like the extra lines on the front and a dotted line of elastic along the top
Dot on some nipples and a belly button and then go wild with dots all over his cape for some lovely texture
You can also add some white lines along a few of the edges afterwards to give him that extra bit of super shine!
