Name(s): Vespiquen
Type: Bug / Psychic
Justification: I think Bug / Psychic fits well, tapping into the whole "hive-mind" thing - something I feel resonates with Psychic. Of course, this causes a huge influx in its movepool and a change in its ability. Most of them are Psychic-type moves, however, there are two that do not fit at first glance. While not all Psychic-types get Thunderbolt and Focus Blast, it is very common among them - Thunderbolt being more common than Focus Blast. I want peoples opinions on this though - I'd be happy to remove them if people think that its a stretch. As for moves removed, I basically just removed most of the Flying-type moves, bar the ones Combee learns (as I think it should probably stay Bug / Flying - afterall, it is merely a drone and not the queen bee). Finally, to tie in the whole hive mind thing, Unnerve is replaced with Telepathy. In other words - a useless ability was replaced with another useless ability (Doubles not withstanding - its actually kind of really cool there).
New Moves: Calm Mind, Psychic, Psyshock, Zen Headbutt, Stored Power, Thunderbolt, Focus Blast
Removed Moves: Air Slash, Aerial Ace, Acrobatics
Altered Abilities: Unnerve --> Telepathy
Name(s): Venomoth
Type: Bug/Psychic
Justification: This may sound weird, but it may fit more of a Psychic type. Moths can be seen with psychic powers in some storys and the fact it has some Gen1 weird moveset syndromes.
New Moves: Calm Mind, Psyshock, Future Sight, Confusion, Stored Power, Thunderbolt, Focus Blast
Removed Moves: None.
Altered Abilities: None.
Name(s): Butterfree
Type: Bug/Psychic
Justification: Butterfree already learns several Psychic moves via level-up and TM, learning Confusion as soon as it evolves and Psybeam later on. Compared to other butterfly Pokemon like Beautifly, it looks more ethereal and otherworldly, and its French name incorporates the word "illusion". Like many Psychic types, its highest stat is Special Attack, followed by Special Defense.
New Moves: Psyshock, Calm Mind, Stored Power, Reflect, Light Screen, Trick Room
Removed Moves: Gust, Air Cutter
Altered Abilities: None
Name(s): Volbeat and Illumise
Type: Bug/Psychic
Justification: They have Prankster, that is very rare to be seen on Bug types, but less rare in Psychic type (Meowstic), and also they have a very poor amount of status type moves to use. Giving them priority Sleep would give them the possibility to find a spot even in OU.
New Moves: Psychic, Psybeam, Confusion, Calm Mind, Hypnosis, Psyshock, Dream Eater, Extrasensory, Cosmic Power, Trick, Heal Pulse, Ally Switch, Mirror Coat
Removed Moves: None
Altered Abilities: None
Name(s): Solosis, Duosion, Reuniclus
Type: Psychic/Bug
Justification: Alright this one's a bit odd but hear me out. The Solosis line are all based on single-celled organisms, harmful ones of which are referred to as "bugs." In fact Reuniclus is capable of learning Infestation, indeed suggesting that these Pokemon are in fact capable of infecting others! They can also learn Signal Beam, which is admittedly not a rarity among Psychic-types, but still. And even if one considers the pun on bug to be silly, I would like to point out that Game Freak isn't above using puns and bad jokes when designing Pokemon; Heatmor, an aardvark, learns Bug Bite through level-up.
New Moves: Bug Buzz, Silver Wind, Powder
Removed Moves: N/A
Altered Abilities: N/A
Name(s): Ledian
Type: Bug/Psychic
Justification: Ledian's Dex entry mentions how its power is connected with the stars in the sky (starlight as energy), and as we see with Pokemon like Beheeyem, Deoxys, Lunatone, Solrock and Gothitelle, usually stars/space-related Pokemon are more likely to be Psychic type so it seems plausible for Ledian to be one. It also has a an alien-inspired face design and since Beheeyem the alien-inspired Pokemon is Psychic type. A quick look at Ledian's current movepool also shows a lot of screen-related moves such as Reflect, Light Screen and Safeguard which seems pretty Psychic-related. It can already learn Agility as a Psychic move and Psybeam as an Egg move. I added the usual moves Psychics get from TMs/Move Tutors like Psychic, Trick, Trick Room, Psyshock etc. and also some flavour-related moves like Cosmic Power and Barrier/Mirror Coat/Magic Coat to expand to the screens theme of the current movepool. To also expand on the Baton Pass-directioned movepool I also added Stored Power. Stat-wise it is also more specially-orientated with a strangely huge Special Defense stat. For some reason Iron Fist was given as a hidden ability which boosts its lowest stat of Attack (base 35!?) and since Psychics aren't known for their fists, I changed it to something more Psychic-related. It didn't really have any useful Flying STABs before anyway so they were omitted. I want to give it Magic Guard to go with its Baton Passer movepool (space-themed Clefairy has it and Psychics like Sigilyph/Alakazam also get it) but if that's too wishlisty maybe Levitate works as a slight nod to its old typing. (Let me know if Magic Guard ain't okay)
New Moves: Psychic, Cosmic Power, Barrier, Trick, Stored Power, Trick Room, Psyshock, Mirror Coat, Power Split, Magic Coat, Gravity, Extrasensory, Hypnosis, Calm Mind, Zen Headbutt
Removed Moves: Aerial Ace, Acrobatics
Altered Abilities: Iron Fist -> Magic Guard
/Levitate
Name(s): Elgyem, Beheeyem
Type: Bug/Psychic
Justification: ALIENS! With their exoskeletons and bizarre alien powers and general alien-ness!
New Moves: Bug Bite (No exceptions), Struggle Bug (No fully evolved exceptions), Bug Buzz. (No fully evolved Specially-oriented Bug lacks it)
Removed Moves: None.
Altered Abilities: None
