Optimus is mashup of ER Prime and Netflix Prime, who uses the ER mould. Basically keeping Netflix Prime's darker blues, but keeping the grey internal joints from ER Prime.Looks cool. Still trying to figure it out what's different - head swaps or stickers?
And stickers to really sell the "G1 toy deco" feel.
Megatron is Siege Megatron with some ToyHax stickers to likewise mimic the G1 toy deco, and Miner Megatron's helmet with the caution deco removed to replicate a sort of G1 Marvel look.
