User blog comment:TerrariamcSwaggins/Hey guys, what is your favorite Monster in Terraria?/@comment-1466854-20131126073748

Hard call. Wyverns are fun when you're first entering hardmode (kinda boring later), red devils combine sought-after drops with the need to dodge instead of tanking, and in terms of just looking cool with an interesting ability, chaos elementals are kinda awesome.

As far as just being cool conceptually, I have trouble pinning it down. Probably Destroyer. I remember the sudden moment of "aw hell no" when I first saw him appear.
