Largo's most prevalent trait is her constant lethargic nature, hence her given name. However, she had a special ability to detect danger and will distract the person by taking his/her stuff and running away, leading them to chase Largo instead and escape danger. This ability is only noticed when Largo stole a valuable necklace from Black Jack and saved both Black Jack and Pinoko from being trapped inside their home during the earthquake.
Largo is a yellow and cream-colored dog of an indeterminate breed. She appears to be constantly sad and lackadaisical, although she will immediately become excited when spurned into action.
Anime and Manga Differences: Edit
