Conversion Notes: The Characteristics, Powers and Skills here represent the minimum found in a nimro, but they are often much higher. This write-up uses Champions 5th edition rules. The Characteristics cost for the SPD takes into account the bonus from the DEX.
The nimro are a race of large and long lived humanoids who stand at least 14 feet tall, often larger. Most have a dislike for titans, elves, dwarves, and humans. Nimro are immune to any heat effects and can exhale a damaging jet of fire. They can see the dark. They are commonly allies with jotan, gigantes, ogres, trolls, orcs, goblins and fire dragons.
Nimro can become almost any occupation and can learn magic or gain psionic abilities.
To learn more about the nimro giants, I suggest purchasing and reading the Rifts Conversion Book by Kevin Siembieda.
