Loopty Goopty/History

Past
Loopty Goopty was the co-founder of Lyle-Loopty Robotics alongside his business partner, Lyle Lipton. During their life, Lyle and Loopty performed inhuman experiments on poor people to expand both their empire and vast fortune.

Then one day, they invented the De-Age-Ifier, a specialized chamber that could alter the age of anyone within, which they planned to sell to the richest people on Earth. However, being so sure of their genius, they decided to test the machine on themselves rather than on someone else like how they usually do, and neglected to switch the device from forward to backward. This costly mistake ended up aging them both into fragile old men. Lyle passed out but lived, while Loopty suffered a fatal heart-attack and died.

"C.H.E.R.U.B"
Once he entered Hell, Loopty appeared at the I.M.P Headquarters and requested that I.M.P kill Lyle for "eternal revenge" on his business partner, explaining that it was because Lyle is going to receive everything because of Loopty's death.

He later appeared again asking about what happened earlier, only to be explained by Lyle who appears as a Sinner Demon, thus reuniting him with Lyle, his best friend and deceased business partner, which exposed his true intentions of wanting to reunite with his business partner.

Lyle and Loopty then wondered what they could do now before they were offered jobs by Wally Wackford, who heard they were inventors. It is unknown if they accepted the job offer.
