After Episode RR, the kind Wicke will be waiting near the left of the elevator at the ground floor of Aether Paradise. If you strategically declined to receive Type: Null outside Poni Grove, this is your chance to get it, as well as the memory drives for Silvally. Regardless, you’ll receive 2 Big Malasadas for speaking to her.
Likewise, following his fall from grace at the end of Episode RR, Faba will be hanging near the northern exit at the ground floor of Aether Paradise. Say “hello” and Faba will humbly (or as humbly as he can) request a battle.
Aether Foundation Faba
It’s been some time since you fought Faba one-on-one. His first Pokémon, Claydol, is slow and bulky. For attacks, it can use Earth Power and Extrasensory for STAB, Ancient Power to damage Ice-types, Grass Knot to trip up Water-types. Dark-types are ideal; Bug and Ghost-types are also fine choices.
Bruxish has reasonable Attack and Speed, but below average bulk. Faba’s has the Strong Jaw Ability, which powers up biting moves. It can use Psychic Fangs for STAB and to shatter Reflect etc., Aqua Jet to go first, Crunch to hit Ghosts, and Screech to lower Defense. Dark-types are strongly recommended.
The Alolan Raichu is a speedy special attacker, as you ought to know by now. This one can use Thunderbolt and Psychic for STAB, Quick Attack to finish off weakened foes, and Nuzzle to deal damage and cause paralysis with a 100% chance. Ground-types are preferable, to avoid Thunderbolt and Nuzzle.
Alakazam you may have fought in Dexio and Blue’s teams. This crafty blighter can use Psychic and Psyshock for STAB (each targeting a different defensive stat), Dazzling Gleam to blind Dark-types, and Disable to stop your Pokémon using a move. Bug or Ghost-types are recommended, or Steel to resist.
Finally, Faba isn’t complete without his trusty Hypno. Attack-wise, it can use Psychic for STAB, Hypnosis to send your Pokémon to sleep, Dream Eater to steal HP from sleeping Pokémon, and Focus Blast to damage Dark and Steel-types. Bug or Ghost-types are the way to go, and don’t forget to cure sleep ASAP.
Teach Faba that he still has a long way to go and he’ll give you a Dubious Disc. This item can be used to evolve Porygon2 into Porygon-Z if it’s traded while holding onto it. Along with the Porygon and Up-Grade gotten from the Aether House, you have everything you need, besides a trade partner of course.
