Interesting question ! But to answer it at the best, I'll make four different posts to detail more on each game about specific ennemies that I liked (and I still like !)
So now in PHANTASY STAR 1 :
The
SWORM : as it is the first foe I've ever encountered in any PS ! So it's someting worth to remember !
Then the
FISHMAN : especially I can remember playing one evening on my belove master system, with my older brother : we started to play it some days ago and had just reach for the first time the shore, just south of Iala if I can remember it (not so sure) and met for the first time with a fishman : then death was at the end of the "fight" !

I can remeber as I'm sure that it was first shore and first death ! So the first game over screnn (there were far more of them after !!

) and the fabulous (short !) music piece, even if it was tied with a sad end !

And to "cconclude" the
MARAUDER (and the Reaper too) but the Marauder is better as : the design was fantastic (I think it's my favourite monster in all the Phantasy Stars) and a tough one too, as his thunder spell was the cause of many torments !
All the
DRAGONS : as it's my chinese astrological sign, and I was always attracted by thos fabulous and fantastic monsters : and in the first one, they are really fantastic and mainly tough opponents (especially the white ones !).
SPECIAL ONE : the
TARENTUL as it was the first monster we have seen in an ad and that is this picture that have decided us (me and my two brothers) to buy this game ! So if I can thanks something that have made me discover this fantastic PS : it's this ad with the Tarentul, on an official SEGA ad paper (that I still have with me : collector one ! ).
Taht is all for the first one but I would like to conclude with that : for me all the monsters were and are still great in this fabulous and legendary game !!!
