Resubbing this one because it works well in this category too.
Name: Mysterical
Type:
Abilities: Rattled
Stats: 46/104/84/104/104/113 (555)
Movepool: Glitzy Glow, Baddy Bad, Spirit Break, Acrobatics, Mist, Recycle, Yawn
Appearance: Ethereal clown mon cloaked in dazzling lights and colored mist.
Flavor: Combination of Mist/Mystery/Mystical and Hysterical (both definitions). Roams people's dreams to feed on fear and stress... but it turns out you are what you eat.
Role: Weakness Policy + Rattled sweeper that can turn around a game on a dime. Psychic's weaknesses perfectly line up so that you will always get both boosts together and never separate. However, the payoff is weighted by the fact that you have to tank a super-effective hit in order to do it. To help make this more realistic, it's set up so that you can viably run max HP + Speed, due to being a mixed attacker with low HP but average defense and above average special defense (where two out of three of its weaknesses are). It also has the coverage to hit all of its weaknesses super-effectively. If you want higher risk, higher reward, you can also invest double-offenses. Or, if you want to narrow options for better payoff, you can go SPA/SPE, since this gives you the strongest offensive potential at the cost of being walled by Steel and Dark, and making it harder to get your boosts as a result. This might be preferred since activating your boosts off Bug gives a smaller physical payoff anyway (since Lunge drops Attack before you get your boosts), which means you'll have a worse matchup into teams carrying a Dark type in exchange for a better matchup against teams carrying a Bug type.
However, due to the somewhat matchup-fishy nature of this, it can also be dual-moded to run in a more supportive offensive-utility role. It can set up screens for its team while simultaneously putting out damage, and the fact that it is setting screens before taking attacks rather than after eating an SE hit means that can survive a bit longer. Mist and Yawn provide some additional team support if you would like. In this role, you can hard commit to screen setting and take Light Clay, or you can maintain your sweep potential by keeping Weakness Policy. This creates a Cold War situation with your opponent - using the
threat of boosting to help enforce its screens, rather than attempting to force them by surprise and sweeping off of it. Psychic protects its screens by beating Fighting, and Weakness Policy + Rattled protects itself by hard punishing attempts to kill it with SE attacks that don't manage to finish the job (which is more likely if it's coming in proactively and thus has screens up). However, it is still ultimately not very bulky and lacks any recovery outside of a Baton Passed Aqua Ring, so a hard-hitting neutral attacker can still wear it down.
On top of that, however, a new concept:
Name: Caleflash
Type:
Abilities: Defiant, Competitive
Stats: 45/63/151/63/151/111 (584)
Movepool: Fire Lash, Sludge Bomb, Scald, Baton Pass, Recover, Defog, Leech Seed, Yawn
Appearance: Ball of hot gas. Ignites when excited, dissipates when startled.
Flavor: Calefaction + Hot Flash. This mon is primarily active in the spring and summer months, riding warm air currents and often traveling long distances with them. This Pokemon is easily agitated, and a cluster of them migrating through an area can quickly cause whole towns to heat up for days.
Role: Fast bulky pivot whose main goal is to switch on stat-lowering moves in the meta for either Defiant or Competitive boosts, and pass those on to its allies. Its stats and split coverage are a little low to try and abuse them itself, but it can still put out respectable damage when needed. Its physical side only has its main STAB, and its special side has two moves that serve as good coverage for mons carrying stat-drop attacks as well as additional utility in status spreading. Recover and Leech Seed helps keep it alive and the latter + Yawn and Defog helps support its team. Its statline in combination with Fire STAB in particular makes it a good abuser of Leech Seed.
