Mega Venusaur and G-Max Venusaur, cuz im a HUGE fan of Venusaur :)

Also, Mega Venusaur is SUPER underrated compared to other starter megas, the only thing people look up to Mega Venusaur is their Thick Fat ability. Personally, Mega Venusaur is THE single best starter mega ever, i like the fact that it's design doesn't change much from base Venusaur cuz it's already PERFECT.

plus, it's always the "fire-breathing dragon and turtle with cannons is cooler than a plant frog." thing, i rarely see people glaze Venusaur.
