User blog:Sonicfan919/Eggman/Robotnik's Family

I'm making a list of and collecting ideas and theory's about Eggman's family. I'm asking because I want to make a fanfic about them because they're possibly the biggest and most interesting family in the Sonic universe. Here is my list so far with their relation to Eggman (not counting ancestors):

Maria Robotnik (Cousin),

Shadow the Hedgehog (Uncle?)

Colin Kintobor (Brother),

Hope Kintobor (Neice (Colin's daughter)),

Mama Robotnik (Mother),

Gerald Robotnik (Maternal grandfather),

Snivley Kintobor (Nephew (Colin's son),

Dr. Warpnik (Cousin),

Unamed father (he appeared in a flashback in the comics),

Robotnik Jr. (robotic son).

Now can you help me? Also inform me if I missed any.
