This is a warning to anyone who is reading this who is American. Prime episode 21 and 22 has not aired yet on the Hub. So if you Don't want to read what I'm about to say about Bulkhead and Ratchet, turn back. Who would you rather have? A Brainy Bulkhead or a Toughy Ratchet? As of the previous episodes aired on Teletoon, It seems like Bulkhead and Ratchet switched places each episode. Episode 21, The lovable cuddly Wrecking ball Bulkhead had been shot with a container which made him smart, Almost like when Sam(from the Transformers movie) had a meltdown, or when Grimlock became smart(I didn't watch that episode, but I saw clips). Episode 22, After the intelligent, Medical officer Ratchet obsorbed some kind of green Energon, he became reckless and tough(like I had to compare him with the Animated Ratchet). It's kinda wierd that it was like they switched places. Now imagine if it remained permanent (I'm not talking about the causes of results they mentioned will happen). Bulkhead could end up doing the energon recharges and repairs, while Ratchet will be all Smash, Bang, Pound on the battle field.
