There are several different werewolves described in GURPS books already, but none of them fit well for a D&D werewolf. Werewolves are not the only lycanthropes, and lycanthropes are divided into three types by the way how much they can control their shapeshifting abilities and how they got it. This post was a big pain.
Locathahs are simple aquatic fishmen who generally are peaceful.
D&D 3.5 has only several lizardfolk subraces, but previous editions had much more. Let's convert them all. Some of them should be within the PC point budget.
Lillends are artistic serpentine outsiders from the plane of Ysgard. Good ones.
Liches are powerful undead spellcasters with their souls hidden in special phylacteries. Unless the phylactery is found and destroyed, the lich is impossible to destroy permanently. Liches make for great villains, and their precious and heavily guarded phylacteries deserve whole adventures dedicated to finding them. Note that this is a D&D lich, its template differs quite significantly from the one in GURPS Magic.
The lammasus are quadrupedal flying creatures who actively oppose evil. Stat blocks are provided for the normal lammasu and the celestial half-gold dragon lammasu also known as golden protector.
Lamias are tauric vile monsters with deceptive magical abilities. Never been a big fan of them.
