Professor Triffid
From Multiversal Omnipedia
Professor Triffid was a scientist from the vegetarian planet called Rhizome. He's convinced that peace and harmony can only be maintained effectively by the power of vegegenetic technology... that is, plants. Buzz Lightyear was very reluctant to use Triffid's technology when dealing with NOS-4-A2, but he learned his lesson at last.
