I would like to repeal both, the dragon and roller submissions, and in their place I would like to submit
Sammy Bros. and
Two Headed Lab Assistant.
The Sammy Bros. are an enemy from Mole Mania, the muscular dudes in the thongs. They can appear in a minimum of 2 and maximum of 4 and will follow one another through a set, looping pattern. (for example: walk to the right on a platform, jump off the platform, walk to the left, jump back on the platform, repeat) When hit they do not recieve knockback, nor do they ricochet when KO'd. They can only be hit with projectiles, if hit up close they'll do a counterattack chop - which can desync them, leading to any that bump going the opposite direction of where they were going. All they can really do is walk, jump, go down platforms, and the aforementiomed counter attack. With an Assist Trophy and Master Spirit, Mole Mania has been recieving quite a decent bit of representation and, while Muddy is disconfirmed, I don't think we should stop at those two pieces of content given Mole Mania is a decently popular bit of lore among die hard Nintendo fans.
The Two Headed Lab Assistant is from Crash Bandicoot. They wield fried chicken as clubs. In this game they will swing forward one chicken, give some time for you to attack, then swing another chicken. The chicken hits don't deal much damage but do a lot of knockback. Once KO'd they leave behind both chicken meals, which you can eat to heal a lot of health, much like Paisy's final smash. I'm only really submitting this because Crash needs an enemy.
I would also like to apologise to Stratos, I was being a bit of an a-double-dollar-hole, I admit. Sorry about that.
