Take a long, horizontal canvas and draw a sprite of a famous game character in the middle (like Mario, Lara Croft, Link, Samus, Gordon Freeman, Doomguy...etc). It doesn't have to look exactly like the original, but it have to be recognisable. Then draw the same character as a baby on the left and as elderly on the right. Try to make the age differences look most obvious as possible. You can draw the baby in diapers, with a pacifier, crawling or even sitting in in a stroller, and the elder with grey hair, arched back or and using a cane.
If you choose a child-like character (like Little Sister from Bioshock) draw it on the left and add an adult version and elder on the right, and if you choose an old lookong character (like Geralt of Rivia) add it on the right, and add baby and younger adult version on the left. Just follow the pattern of 3 stages in live of a game character, from a child to their old age, from left to right.
