I think I've got this figured out....it's not Waldo.
It's Odlaw:
For context:
Odlaw (Waldo spelled backwards) is a classic example of the "evil twin" archetype and resembles the titular Waldo, but has a black and yellow patterned shirt, and a mustache - what makes Odlaw most different from Waldo, however, is not his physical differences but his behaviour.
Odlaw is described as disputatious, acquisitive, unpleasant, loathsome, uncaring, repugnant, traitorous, duplicitous, manipulative, blameworthy, unmerciful, obnoxious, ruthless, hateful, greedy, rude, cocky, snooty, selfish, menacing, sadistic, conceited, diabolical, egotistical, unscrupulous, argumentative, cantankerous, prejudicial, avaricious, conniving, possessive, contentious, delinquent, and unlikable in almost every way
