Introducing the Grass Starter Line, Mosslug!
Mosslug
The Grow on You Pokemon
Grass
Their parent pokemon abandon their eggs in random parts of forests and wooded areas. It's up to the newborn to use it's cuteness to survive.
Leashoom
The Leach Resources Pokemon
Grass
Having been pampered and spoiled for its entire life, it truly believes that everyone and everything is to serve it. It will often watch nesting Pokemon to find their habits, then attack and eat the eggs inside once they know the parents are busy.
Trovelet
The Trojan Flame Pokemon
Grass/Fire
Those that once cared for it wised up and abandoned it, leaving it all alone. Molten hot anger pulses under this Pokemon's skin because of this. It pretends to have changed, and plays coy getting close to prey. Then it shoots strands of boiling hot silk that can melt anything, and eats the trapped prey alive.
Mega Trovelet
The Trojan Flame Pokemon
Grass/Fire
It's flames burn thrice as hot as the sun. Many fear it's wrath, for its burning anger rivals the gods themselves. Beg for mercy should you attract its ire.
