Here are Dr. Krankcase and Chef Pepper Jack when they were children. However, they won't meet each other until Pepper Jack first joins the Doom Raiders while Krankcase was already a member as young adults.
Now as for their voice actresses:
Young Dr. Krankcase: Tara Strong *Who voiced Timmy Turner in the Fairly Odd Parents*
Young Chef Pepper Jack: Grey DeLisle *Who voiced Prince Puppycorn in Unikitty*
The list of characters and/or drawings were originally drawn on the 3DS Game Notes then traced on Painting Workshop.
