Optimus transforms into a pretty large blaster. It can be held by all 5mm compatible Transformers and obviously is a part of Beast Alliance. There's not really any information about the toy, but I like to think it shoots large electrical blasts. Primal's ape mode was inspired by King Kong, so it's only natural that Kong's lightening abilities be reflected in this gun mode. I'm obviously thinking too much about a silly little toy of a gorilla that turns into a gun... but that's fun to do. I really like how these are making me think alot about other things. Rise of the Beasts has some great toys, and this is another one.
