Cacturne

Cacturne is certainly an odd Pokemon in VGC. With base 115 Attack and Special Attack, its stats are geared towards offense, but its low defenses cause it to take damage as hard as it can deal it out. Its base 55 Speed is fairly low, but can be seen as a blessing in disguise: it can be effective both in and out of Trick Room based on how its Speed is managed. Cacturne's unique Grass / Dark typing, along with Sand Veil and Water Absorb as abilities, gives it several niche roles on teams. Potentially usable in rain, sand, and Trick Room, this cactus can become dangerous if underestimated.
