Lizardmen --- are swamp-dwelling saurianoids about seven feet in height when fully grown. Members of the more advanced hut-dwelling tribes can speak a hissing version of Common in addition to their own tongue, and occasionally seek out employment as muscle in more civilized areas. A character should have a 13 or greater strength in order to be a lizardman. They progress as members of the fighting class, but due to their size and strength gain a bonus hit point at first level and attack on the Monster Table for 1 to 8 points of damage when employing a weapon. Claws and teeth also allow them to attack for 1 to 6 points of damage without weaponry. Their scaly hide affords protection equivalent to chainmail (armor class 5) but due to their affinity for swimming they shun metal armor of any type other than a shield. They move at twice normal rate in water.
---Adapted from comments I first left to a post in the Holmes G+ group, with some changes on further reflection.
---Holmes has lizardman guards in two Boinger & Zereth stories, The Sorceror's Jewel and In the Bag. One speaks with a hiss and the other wields a halberd (much like the image above). Holmes uses the term "saurianoid" in In the Bag, and "saurian" in the other story.
---The height of seven feet, and the concept of more advanced hut-dwelling tribes, comes from the Monster Manual.
---The stat details comes from the Holmes Basic entry: AC 5, HD 2+1, AT 1, D 1-8 with spear or club. The bonus hit point at first level leads to a total HD of 2+1 at second level, meaning a 2nd level lizardman fighter here is equivalent to the monster version.
---Compared to a first level human fighter they get +1 HP and +1 damage, but with a loss of 2 points of AC (no plate mail). If using variable damage for weapons, you can give them a +1 to damage or step the dice up one notch (d8 to d10, etc). Using the Monster Table (which varies slightly between OD&D and different printings of Holmes) for attacks means a lizardman fighter will generally attack better than a human fighter of equivalent level, but their AC will remain much worse without magic armor (e.g., no plate mail +2). In addition to shunning metal armor, magic armor would generally not be available that fits their size and proportions.
