OK lotta stuff here lel
Victini: Victini is Hack Guy's favourite Pokemon so I chose that.
Lag:
Hack_Guy is known for having shit internet and constantly lagging out, so yeah. Lag gives Hack Guy a 20% chance to move last in his priority bracket, and if this happens then 6 random users say "nice dc". It also acts as Victory Star. (Summary: Lag=Victory Star+20% chance to act like Stall)
V-Turn: You probably already guessed this lol, but it is just a combination of V-Create and U-Turn (in that order), one of Victini's main niches in Linked, Hack Guy's OM. (Summary: V-Turn=V-Create+U-Turn)
Double Fusions: Again, one of Victini's niches is spamming an extra strong Fusion Flare after using Fusion Bolt, so Double Fusions is Fusion Bolt then Fusion Flare. (Summary: Double Fusions=Fusion Bolt+Fusion Flare)
Wifi: A lot of things happen in the Wifi room. One of them is trades, so the first part of this move acts like Switcheroo (or Trick but Switcheroo is more relevant as you switch Pokemon :p). The second thing is people intentionally pissing off the auth by doing stuff like t y p i n g l i k e t h i s so the second part of Wifi is Taunt (summary: Wifi=Switcheroo+Taunt)
GOTTA GO FAST: So a little back story is necessary here. Recently, Hack Guy has been breeding for a Shiny 5IV Beldum with a Jolly Nature. He ended up with a 5IV shiny one, but with 31/31/31/31/31/8 IVs, instead of x SpA. This is why I set the IVs to 8 Spe, the Nature to Jolly, and made him Shiny. He told me he was fine with this Beldum, because "I'll just spam Agility until I outspeed everything". GOTTA GO FAST grants Hack Guy +3 Speed :] (Summary: GOTTA GO FAST=1.5*Agility)
