What is the downgraded version of the Grass Ultimate Starter Move?

Question

Such as:
Fire Blast & Blast Burn
Hydro Pump & Hydro Cannon
??? & Frenzy Plant

Comments

I don't think there is a deliberate relationship between those moves. I'd put the similarities between Fire Blast and Hydro Pump down to coincidence.

Answer 1

Fire blast and hydro pump both are special and have 110 base power and 5 PP. No grass move fits this pattern.

Answer 2

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
