I didn't want to post this cause i'm not done working on it yet but what ever.
Heck i don't even have a back story for this guy or do i ?

S.I.-31 (Nicknamed: Leviathan) is a artificially formed life form created for the purpose of ground-to-orbit attacks using a built in plasma cannon in it's throat, and to support of ground units with artillery fire. It's size from head to tail is slightly over 1,000 feet. All S.I. units have cores which act as a power generator or heart(s) for every model. The S.I.-31 size demands a hell of a lot of energy to even stand. The core can supply that energy, but if it were to take moderate damage, the core would explode in a similar fashion of how a tank will blown up inside out by it's own damaged ammo rack.
Despite this flaw, which human sized S.I. series don't share, Leviathan can prove to be a persistent harasser to orbiting fleets. Leviathan get's its nickname to it's preferred habit to attack from the sea.

This is what you get when you mix Godzilla with a battleship, some cybernetics, glowy green stuff, and a hint of whale from the Dishonored video game. (btw those are supposed to be cannons on it's back.)


Sorry im terrible at writing descriptions. :3
Hope it's good so far, might work on it some more later... or not.
