Funny thing about Lifeline Ratchet...well not really.
despite being a great medic,w hat he has seen has made his processor susceptible to rage, if he feels that something is going to get in the way of him saving someone's life. When a commanding officer shot a guy that Ratchet was repairing, because said officer felt that his own repairs were more important, Ratchet beat him half to death with a pipe, and has since declared that his signature weapon is a pipe.
Primes choosing of him as a head medical officer is one of the reasons Prowl hates Optimus..and yes Prowl only knows Cyber Ninja FIGHTING techniques, he feels that the rest of the teachings were mostly bull and his current students are just learning the moves from him.
Hey, I suggested this idea to Zombiebot and I'll suggest it to you as well.
For a special Halloween image, you should dress up one of your characters as a classic Universal monster. Ideally, I think Guiltar or Stinger could work as Frankenstein's monster. The former seems more logical, since he's a mix of two bots kind of like how the Monster is made from multiple dudes.
I'm also considering the idea of dressing my Megatron up as Dracula.
