TROPIUS! I wouldn't want a gym. I wouldn't want anybody's pokemon to hurt my poor Tropiuses. Tropiui? Tropiuss? Many Tropius? How do you pluralize Tropius?
I'd probably go with the Japanese method of the plural and singular being the same word, and using numbers. As in, one can have one Pokémon or twelve Pokémon.
Aha! All hail teh geniusness of our fearless leader! *bows down before the great Nethilia* *many random voices chant together* ALL HAIL NETHILIA, THE LEADER OF ALL!!! blaugh
