Fire Blast & Blast Burn
Hydro Pump & Hydro Cannon
??? & Frenzy Plant
Fire blast and hydro pump both are special and have 110 base power and 5 PP. No grass move fits this pattern.
The closest you can get would be Power Whip. Unlike Fire Blast or Hydro Pump, this one is a physical move and it also has better damage and accuracy at 120/85 compared to 110/80 of the other two
