Is that a Red Comet Reference?
No, it's Armored Trooper Votoms reference. The red shoulder plate is reference to Chirico Cuvie mecha ATM-09 Scopedog or the fact that he is the last Red Shoulder Battalion and the reference no bullet hitting is Chirico have pretty heavy plot armor that is actually a plot in anime. He practically immortal, he can dodge bullet, weapon will fail when shoot point blank, survive heartshoot, survive explosion, heal injury in days that take months, survive burning, survive freezing, survive reentry atmosphere.
