Yeah, it's Bruticus, who transforms into a Cerberus. The robot mode is also multi-headed too. :)
Others include:
+ Hun-Gurrr
+ Sinnertwin
+ Doubleheader
+ Gigatron (aka RiD Megatron) / Devil Gigatron (aka RiD Galvatron)
I love the way Doubleheader talks -- sometimes his heads talk independently, yet one head talks about the other head in first person (even but in a second person context!), other times Doubleheader's speech is divided between the two heads where one finishes off the other's sentence... sometimes they both cut in and say the same thing at the same time which seems to come at a surprise to both heads! :D :cool: Beast Wars Megatron technically isn't multi-headed, but if you look closely his beast-headed hand is often portrayed as another head. e.g. it looks at Megatron's head and Megatron occasionally pets/strokes it -- even brushes its teeth at one stage! There was also one time when Megatron's talking to someone else, but his beast head is intensely watching computer monitors -- thus allowing Megatron to focus on two different things at the same time and multitask! :D
