I thought that Bloody-Tooth Fungus was a food at first...maybe I'm turning Bug type...
Anyway, I was thinking: what about a basilisk-style Pokemon? It could be a Grass/Poison or pure Poison and utilise some Water-typed moves (since they run across water and swim) as well as Glare (for the legendary staring abilities), Iron Tail, U-Turn and the Fangs. Could evolve into the biped basiliscus series of basilisk (sorta like Quilava to Typhlosion) and gain Earthquake, Crunch and the like. And for a branched evo...maybe something like a Dimetrodon?
Ability-wise: Intimidate and Swift Swim with Overcoat for DW/whatever.
Stats: Low HP (50), High Atk (110), Mid Def (70), Low Sp. Atk (45), Mid-high Sp. Def (85), Great Spd (115). For evolved form of course.
As for names...maybe Basilene/Chriskos -> Corylusk/Regul? Okay those names suck, but I'm not good at that.
Soo...sorta like Ninjask if he were an attacker I guess? Probably not balanced either but oh well. I just like the concept.
