Let's be fair, for every monstrous villain, there's one who is a pushover, one who doesn't take long to beat for one reason or another. For the Teen Titans cartoon that was Dr. Light. Ironically, he is a bit more capable in the comics themselves, but here, he's portrayed as a somewhat powerful but incredibly dumb villain.
Now, the writers did give him some moments to shine, and certain episodes proved he wasn't completely incompetent. But, more often than not, he's beaten within minutes, if not seconds, of appearing. One time Raven literally scares him into surrendering.
