Gen 9 has made this little guy a viable option. They were too scared to put him into the dex for they knew what he could do.
I run this guy on my Gen9 NatDex team and no one knows what to do with him. You can bait people into using Water Moves on you with a simple Fire tera typing, and it also removes that 5x fire weakness Parasect has with Dry Skin and turns it into a 1x weakness.
This guy is basically for mindgames and switch ins. But he's come in super clutch.
Entry hazards are this guy's weakness, so make sure you have a defogger, or something like that. It's also good to have him on a Rain-based team. He's also super slow and defensively weak, but he has pulled off some clutch moves for me. It's not about a Pokemon's **** stats or whatever. It's about how you use them to enact mind games onto your opponent. No one expects psychological warfare Parasect.
If all else fails, you can get a Spore in to tackle a troublesome Pokemon. Not a bad deal.
Also, who could hate this cute little guy?
