Tavros Nitram

adiosToreador, or AT, is the chumhandle of the person who tried to troll Dave Strider, but was incredibly unsuccessful at it. His chumhandle is based off of the Zodiac sign Taurus. Like GA, and someone else, he also has a bizarre typing quirk. He types in maroon. His grammar is kinda crappy, using commas instead of periods, but, like WV, he seems to have the caps lock button on, resulting in lowercase letters at the start of sentences and proper nouns, with the rest capitalized.

He attempted his attack on Dave's birthday, just as grimAuxiliatrix tried on Rose. Both mentioned how they were from the future and nonhuman, and both Dave and Rose pointed out their lack of skill at trolling. They have also both talked to them in the child's future. But whereas GA eventually forged a kind of friendship with Rose, Dave met AT's weak attempts with a thoroughly effective homoerotic counter-troll, eventually causing AT to block him.

If we are to assume that each troll corresponds to one of the Children, AT might be related to Dave.
