In Pokémon Ruby (and Sapphire/Emerald) the three starters are Treeko (Grass type), Torchic (Fire type) and Mudkip (Water type).
Treeko (Grass), Torchic (Fire) and Finally Mudkip (Water). Treeko evolves into Grovyle (Lvl. 16) and then Sceptile (Lvl. 36). Torchic evolves into Combusken (Lvl. 16) and then Blaziken (Lvl. 36). Mudkip evolves into Marshtomp (Lvl. 16) and then Swampert (Lvl. 36).
I assume you mean other than Torchic (Fire Bird), Treeko (Leaf Lizard), and Mudkip (Water Pokemon). The fact is, you can't.
Treeko is a grass starter Pokemon in Pokemon versios. Ruby, Sapphire, and Emerald. GBA
you need to have a friend or have 2 game boys and 2 ruby versions and trade them to the right ruby game you wanted them on
There are a lot of Pokemon that can learn Cut, a tip would be to look for a Pokemon with claws or something sharp on it. Here are some that can be found early on in the game, Treeko, Torchic, Nincada and probably Shroomish.
