Doctor Terminal devours a bunch of zoo animals. Firstly, some context for the feat;
Due to Doctor Terminal's Eisenstein's Syndromme, he has a machine that turns matter into energy to hold off the disease, but that makes him incredibly hungry. So this should be pretty straight forward. He eats an elephant, a giraffe, two hyenas and a raccoon. Quickly searching up the mass of each animal, spotted hyenas usually weighs between 22kg to 64kg (or an average of 43kg, and given there's two that's a total of 86kg), a raccoon weighs between 3.5kg to 9kg (or an average of 6.25kg), giraffes weigh 800kg an elephants weight between 2700kg to 6000kg (or an average of 4350kg).
M = 86kg + 6.25kg + 800kg + 4350kg
= 5242.25kg
Now we just need our energy.
E = mc^2
= 5242.25 X 299792458^2
= 4.71149934e20 joules
= 112.60753680688337397 gigatons
Final Results
Doctor Terminal devours zoo animals = >112.608 gigatons And given that Doctor Terminal was sucking up the ground too, and later whole skyscrapers, who would ultimately be even more powerful.
