Meganium

Among the plethora of Grass-types available in RU, Meganium truly doesn't have too much to offer over its competition. However, with its good all-around bulk, and access to Aromatherapy and Dragon Tail, Meganium does have a niche in providing both moves in one teamslot, and with its lack of a secondary typing, it keeps useful resistances to Electric-, Ground-, and Water-type moves that some other Grass-types do not possess. Outside of this role, however, Meganium suffers immensely from its low attacking stats and weaknesses to common types of moves such as Bug and Fire that leave it weak to common threats such as Entei and Escavalier. Unless you need the specific role Meganium provides, you are probably better off using a different Grass-type such as Amoonguss, Tangrowth, Torterra, or Roselia.
