Ouroboros 23

ouroboros 23 was a prototype robot developed by apex cybernetics before the creation of mechagodzilla to exterminate the titans before the overall creation of mechagodzilla.

the ouroboros prototype was a giant mechanical snake with an ion power core for emergencies and a nuclear reactor as a primary weapon, eventuallly a proton scream replaced the nuclear reactor. it's weapons also included 2 missile launchers and 12 laser machine guns, a secondary proton scream combined with the nuclear reactor. it was tested against a few skullcrawlers and an icarus tiger and proved succesful. the only draw back was when crawling it would damage the weapons, sensors and many onther tools of the mech. hence it being replaced by mechagodzilla, a stronger reptillian version with more weapons and advanced sensors.
