Hedgehog day continues with some more peeks at Sonic 4-2 concept art. This time in the form of the first Eggman boss reveal! This one is called “Serpentleaf” and besides sounding like a Pokemon, this giant plant mech seems to house a laser-firing Eggman within it’s pedals. The rest of the concept art shows that this first image is just the tip of the mecha-monster. He’s a quite a big boss for our blue blur to tackle. Now I want to say he’s an original creation for this game, but I know someone in the comments will prove me wrong and he appeared in like, Sonic Blast on Game Gear or something so forget it! Read on for more images of this budding, blossoming bad boy.
