I vaguely recall seeing a D&D conversion of the island-dwelling terrestrial hunting bats (whatever they were called) but it's so long ago I can't remember the details. I think it was in a magazine or something like that?
They were called night terrors I believe.
That sounds familiar, hold on while I "check the internet"…
…Well we're half right, the beasties were called Night Stalkers.
Nice. Now how about the surfbats?
I don't recall ever seeing a D&D conversion of those.
The vast majority of the creatures in After Earth seem lacking in the special qualities that make for a memorable D&D monster, namely "new and interesting ways to kill the PCs".
Would any of them work as familiars or as paladin steeds?
