Megatron is a fictional character, and the main antagonist, from the Beast Wars and Beast Machines animated series and toylines, part of the Transformers multiverse. In the past, fans have referred to him as Megatron II (although this term is frowned upon) to distinguish him from the original Megatron; in the Japanese series, he was named Beast Megatron for this purpose.
Megatron (known as Gigatron in Japan) was the merciless leader of the Predacons (Destrongers), including Sky-Byte, Slapper, Darkscream and Gas Skunk, in . Megatron is a Six-Changer, powerful enough to transform into five additional modes besides his robot form - twin-headed dragon, bat-gargoyle creature, race car, jet and claw (GigaDragon, GigaBat, GigaFormula, GigaJet and GigaHand in Japanese). Each form has its own different frightening capabilities, making Megatron a very unstable and unpredictable fighter.
