Power Lens not working for IV breeding

O-Powers can be thought of as skills used by the trainer instead of his/her Pokémon.

Unlike a Pokémon's PP, the trainer's energy restores over time. The amount of energy available to use an O-Power is represented by the number of orbs in the bottom bar.

O-Powers can level up when used often. Higher levels mean greater effect, but also greater costs to use.

It is currently unknown how many O-Powers there are in total, but here are the ones I've found so far:

• 3 minute powers¹
  • Bargain Power: Poké Marts begin a bargain sale in which everything is x% off.^a
  • Prize Money Power: Increases the prize money from battles.
  • Exp. Point Power: Increases the Exp. Points from battles.
  • Capture Power: Increases the chance to catch Pokémon.
  • Encounter Power: Increases the chance of encountering wild Pokémon.^b
  • Stealth Power: Decreases he chance of encountering wild Pokémon.^b
  • Befriending Power: Helps Pokémon grow friendly faster.

• Instant powers
  • HP Restoring Power: Restores the HP of the lead Pokémon.
  • PP Restoring Power: Restores the PP of the lead Pokémon.

• Battle powers²
  • Attack Power
  • Defense Power
  • Sp. Atk Power
  • Sp. Def Power
  • Speed Power
  • Critical Power: Raises the critical hit ratio of the lead Pokémon during battle.

New powers are given to you by a man calling himself [...] Mr. Bonding, the expert on O-Powers. He is usually found in hotels or Poké Centers.

¹: Including time spent in combat
²: Only active for the next battle. If more than one are used at once, the effects will be added progressively each turn, e.g: the Pokémon receives an Attack boost during round 1, then a Defense boost during round 2 and so on.

^a: x% is 10% for level 1.
^b: Cannot be given to others.

It will be Meadow.

The attributes of a pokemon egg (EG its stats, nature, moves, IVs, etc) are all determined as you receive the egg from the daycare man, not when you hatch it. So your friend will get a Meadow vivillon.
