- Base-Breaking Character:
- The Fakemon Legendaries in Prism. People either think they're well above usual Fakemon standards as far as hacks go and don't look too far off from regular Pokemon, or they get accusations of falling into the same cliches Fakemon use and/or don't look like Pokemon to begin with.
- Earlier, the same criticisms were made about the now-scrapped Prismeon, which would have been KoolBoyMan's original contribution to the ever-popular Eeveelutions. The Walking Spoiler nature of this Pokemon also magnified the fans' reaction to it when they found out about it. Eventually, it was scrapped sometime before the aforementioned Legendaries.
- Breather Boss:
- The third gym leader of Prism, Brooklyn. She has only three Pokémon, one of which is a pre-evolution of the other, and all of which the player has faced earlier in the game.
- The sixth gym leader of Prism, Ayana. Like Brooklyn, three of her four Pokémon are ones the player has already encountered, two of which are used by her own trainers. Furthermore, because of their weakness to Fire-type moves, a faster Fire-type Pokémon could sweep all three of them. This isn't so much of the case of her wild card: Drapion, a Lightning Bruiser which doesn't have a weakness to Fire, and in fact can use Earthquake to counter them.
- Early-Bird Cameo: One of the legendaries from Prism, Phancero, made a fully-playable appearance as a Bragging Rights Reward on another popular Pokémon Crystal fanhack earlier in 2016, as the only Fakémon available there. Granted, it is the pokémon form of OLDEN, so in a meta sense it's justifiable.
- Ensemble Dark Horse: Phancero, thanks in part to Twitch Plays Pokemon, has gained a decently-sized following. To the point where it's become a mainstay in TPP lore and even appears in their dev team's own ROM hacks.
- Hilarious in Hindsight: Rijon Adventures features a female professor named Jen. Years later, Pokémon Black and White would introduce its own female professor, Juniper.
- Sequel Displacement: Being a more developed, expansive game, Prism gets more attention than Brown.
- Surprisingly Improved Sequel:
- Pokemon Brown was supposed to be a sequel to KoolBoyMan's earlier Fukemon. Whereas Brown and Prism are one of the most innovative ROM Hacks of their kind, Fukemon has been relegated to Old Shame.
- While the quality of Brown had few doubting that Prism would be a solid production, the sheer scope of the changes and the vast amount of new features Prism packed in resulted in thoroughly-impressed adulations from players after the leak.
- That One Boss: Fighting-type gym leader Andre comes at the end of a tough segment of the game, and uses a well-rounded team that covers the typing's weaknesses and capitalizes on its strengths. Three of his four Pokémon - Gallade, Lucario, and especially Machamp - are top-tier threats that will be a nightmare to unprepared players. Thankfully, he doesn't appear in the final Naljo gym's Boss Rush (probably because his anti-civilization outlook wouldn't allow for it).
- That One Puzzle:
- Invoked by one of the sages in Magikarp Cavern, who turns you into a Magikarp and puts you in a brutal rapids puzzle to show you the trials wild Magikarp regularly face.
- The jewel puzzle in Naljo Ruins has tripped up some players, as it's impossible to proceed unless the player remembers that they can jump over small gaps with the Jumping Shoes.
YMMV / Pokémon Brown and Prism
