The only Transformers comic I keep looking out for is pretty much anything related to Beast Wars. Those are the ones that interest me more than anything.
For me, my favorite thing going on in comics right now is Blackest Night from DC. The whole event has been 5 years in the making, ever since Green Lantern: Rebirth. GL has been my favorite comics out ever since Rebirth, and it continues to be. The Flash: Rebirth is also going awesomely as well so far. Essentially, anything that Geoff Johns is writing, I'm probably collecting. His run on Superman is easily the best the comic has been in so very very long. His update of his origin, Superman: Secret Origins, is thus fan brilliant. Also, Morrison's Batman & Robin is also another one of my favorite comics out now. I love Damian. He's [tornado fang]ing awesome.
