#SentinelComics has great methods for making heroes and villains. And I've found that villains, in particular, is fun as they're way less equal.
A villain is composed of an Approach and an Archetype. These two choices, and their sub-choices, help make anything I can think of.
You can make villains of every kind. Relentless predators that exclusively hunts their target, cocky swordsmen that get more dangerous the more outnumbered they are, underpowered weirdos way over their head, and one-trick chumps with limited repertoire.
Doesn't matter if it is a time travelling wizard with clockwork minions, or a massive insect kaiju, or a Superman-stand in turned evil, or even just a particularly angry hot dog stand vendor; Sentinel Comics can handle it.
And that's what I love about it.
The game can do anything, which is what a superhero #ttrpg should be able to.
