Peco, or Pecoros, resembling an onion in appearance, is another support character in Breath of Fire III. He is an abnormal creature borne from the chrysm experiments conducted in the Plant. Peco has very limited speech, but can communicate quite capably with the revered tree of wisdom - Yggdrasil.
In battle Peco is capable of using different status inducing and attack magics, however his real strength lies within the amount of HP he has. Peco also has the highest reprisal rate of any character and his health replenishes slightly after each turn in battle.
In the camp scenes he is often found sleeping, muttering riddles to himself, which Ryu seems to be able to understand.
