I'm working on a hack, and one of my main goals is to explore as many type combinations as possible.
The Fairy type adds a lot of options.
And- whilst true that a lot of the unused types combos
are unused because they'd either have a huge number of weaknesses, a bunch of double weaknesses, or just don't make much sense- that challenge is exactly what makes it fun for me.
A couple that I've already started work on. Designs close to final, and starting figuring out movesets, stats, etc.
Starters:
Fire/Flying - Based on a Pegasus and Apollo
Grass/Rock - Mountain Gorilla
Water/Fighting - Narwhal
The new types are gained only at the third stage, and change the dynamics. If I ever get this game done, I think it would make the rival battles more interesting. Would certainly be a surprise the first time you encounter the third stage.
Legendary Trio:
Fire/Water -Geyser
Water/Grass - Kraken/Kelp
Grass/Fire - Forest Fire
None of them have the one-up on the others, and each only have three weaknesses.
Making use of the new Fairy type:
Rock/Fairy -
Inuksuk The Inuit built them for navigation. Some lore marks them as spirit guides.
Grass/Fairy - Dryad
Ice/Fairy - Jynx evolution with drastic design change. I've always liked Jynx's concept and unique type combo- but could never use her
without feeling like a horrible, horrible racist.
Random Others:
Ground/Fighting - Warthog
Electric/Dark - Thunder Serpent in Native American lore. Interpretations vary, the more commonly known being the
Thunder Bird.
Ice/Fire -
Chinook. Powerful, warm winds that can give you a random week of summer in the dead of winter.
Normal/Ghost - Ghost bear. I am drawing a lot of my ideas from Native American mythology.
Fire/Poison - Napalm. Chemical Warfare.
Ground/Psychic - Babylonian Sphynx (Male only)
Ground/Dark - Greek Sphynx (Female only)
Anyways, I only brought this up because I saw a couple of those exact combinations being mentioned in this thread, so I was just demonstrating that they are- indeed- workable. Just need to be creative.
If I get a scanner, I could even post sketches if people are curious.
