What does it matter what he thinks? It's not like it matters to you anyway... Not at all...

TFW you have severe abandonment issues 'cos Megatron was a shitheap who decided dumping you was better than dealing with "the teen years" and now you have a self-destructive desire to best him in combat and prove you're not 'worthless' or 'useless' no matter how terribly injured you get and DO YOU LOVE ME NOW DAD!? DO YOU!? HAVE I PROVED MYSELF TO YOU YET!?

He's a bit messed up...

Also, the guidelines on violence and the general rating says: "must not be gory or sexual in nature or heavily detailed/realistic"
So I dunno if robo-blood counts and one kiiiiinda realistic black eye, but if you think it does I'll gladly change it.
