Cool robot.
The design is not fully finished, but i do like it, basically a big mechanical draconic monsterslaying machine.
In my Cosmic Halberd setting, monsters can only be slain if you put yourself at risk of them.
When it comes to truly giant monsters, like kaiju, it means the most consistently effective way to kill a giant monster is with a big badass robot.
Sadly these mechs are very expensive, mostly due to the high cost of the fuel, and some monsterslaying guilds instead try to manipulate giant monsters into fighting eachother as a more budget-friendly alternative, which can work, but is also very dangerous, especially if one or more of the monsters survive their fight.
The robot's weapon is meant to be a hybrid between a halberd and a swordstaff/chopping spear.
Safirion has a fake pilot in the head, which is meant as a distraction, so monsters will not focus on the thicker torso where the real pilot is controlling the machine.
Safirion can regenerate parts of itself by spending large amounts of energy, but it should be done sparingly, as to prevent it from running out of juice in the middle of combat.
It can also ROCKET PUNCH! with it's claws, and pull them back with strong metal wires, or something similarly long and tough, like a thick cable.
