Todd Zarnecki is a minor character who appeared in "The Zarnecki Incursion". He is a hulking teenage nerd who hacked Sheldon's World of Warcraft account and stole all of his virtual stuff including his battle ostrich (as well as a Klingon bat'leth that Sheldon brought in an attempt to confront him), but returned it after being kicked in the groin by Penny.
- Todd Zarnecki is portrayed by Sons of Anarchy actor Christopher Douglas Reed, who stands 6 ft 6 in (1.98 m) tall and weighs 375 lbs.(170 kg).
- This character is commonly mistaken for the much smaller, unnamed member of Wil Wheaton's entourage who appears alongside Captain Sweatpants and Lonely Larry and is actually portrayed by Jesse Heiman.
- Items stolen from Sheldon: enchanted weapons, vicious gladiator armor, wand of untainted power, all his gold and his battle ostrich named Glenn - the only bird he ever loved (in Todd's initial hack of Sheldon's account), and the Klingon bat'leth (after Sheldon and the others first went to confront Todd).
