Notes:

realized I have enough stuff to reenact the final scene of the hashmal arc of iron-blooded orphans.

everything you need to know but you only need to see the final 5 minutes (more or less) to get this scene

gigastorm = hashmal
mechagodzillas = plumas
starscream = barbatos lupus
prowl = graze ritter
grimlock = helmwige reincar
arcee = reginlaze
