Transformers Hero Mashers Optimus Prime, Megatron, and Grimlock, and Maybe Starscream.

The next group of Hero Mashers are out, and Transformers are their game. These are nice as they stay close to the original classics with a few pulled from various other times. They are similar in build to the Marvel, with maybe removable hands this time as well. Optimus Prime and Megatron mid sized sets are pretty fun, with lots of extras. These are worth picking up a few, and maybe some Marvel too, to build some pretty crazy stuff. If you are not into mixing, some make really good stand alone action figures too.
