Victreebel

Victreebel finds a niche in RBY Ubers thanks to its decent Speed and access to Wrap, dual status moves in Sleep Powder and Stun Spore, and a strong STAB Razor Leaf. Wrap makes it tricky for paralyzed Pokemon to block sleep, as Victreebel can use Wrap on them for free chip damage. Wrap can also make Victreebel dangerous late-game, heavily punishing teams that allow paralysis to spread throughout their Pokemon, as well as teams with many slow Pokemon, such as Snorlax, Chansey, Exeggutor, and Rhydon. Victreebel also enjoys the lower usage Alakazam and Starmie have compared to OU, as outspeeding and paralyzing it is one of the most consistent ways to take it out.

However, Victreebel has several flaws that prevent it from being one of the top threats in the metagame. Wrap is only 85% accurate, which is troublesome, since Victreebel often needs to hit Wrap multiple times in a row, and one miss can get Victreebel paralyzed, effectively making it useless. Although its Speed is decent, it is still outsped by Mewtwo, Mew, Tauros, and Zapdos. This generally means Victreebel needs heavy paralysis support to function. Unparalyzed Mewtwo in particular is a terrible matchup for Victreebel, as it threatens both Thunder Wave and STAB Psychic. Mew carries Thunder Wave often, and Tauros threatens Body Slam paralysis. Victreebel is also completely blanked by Gengar, which is immune to Wrap and has a resistance to Razor Leaf. However, Victreebel still is able to threaten all of these Pokemon with status moves. Lastly, Victreebel faces competition from Pokemon like Exeggutor and Chansey as sleepers and from Dragonite as a wrapper.
