Tapu Koko's freaking speed is high. I voted him because his design resonated with me more, but I do like Finn, whoea terrain can basically reject Toxic.
I love Tapu Lele's idea and concept a lot. What I love more, though, is its sheer power competitively. STAB + Psychic Terrain + Specs Psychic really hurts.
Tapu Lele for the win, it is pink, the best color of the rainbow not on the rainbow, also the psychic terrain is a beast for this Pokémon.
I've never used any of them in battle, but I like Lele's design the best. It looks like it's sitting in its shell and I find that adorable for some reason. Koko is a close second.
Tapu Lele for many reasons. It looks kinda cool and it was the easiest to catch so I didn't spend us much time catching it. Although for me Tapu Koko is in a close second.
Tapu Lele for the win! It's cute, a Psychic Type (I love Psychic Types), and it's a little butterfly, how precious However, my sister caught all of the Tapus, so feel free to agree or disagree on this based on capturing it, @[member="WolfeyStar"] .
I personally like Fini the best, purely for looks. It kinda looks like a swordfish to me, adding on to it's water-y aesthetics. I think all the Tapus have the same catchrate. Bulu was NOT nice to me, but Lele was caught pretty fast. Fini put up a fight, but it's worth it for best Tapu. (and aaaa thanks for summoning me here skittle)
I like either Koko or Fini, I can't decide. Both are cool-looking. I haven't used either much yet, and I don't care about competitive battling, so my preferences are based upon design alone...
Competitively I like using Tapu Lele the most, however Tapu Fini is my favorite overall because it is pretty strong and has a more elegant design. Fini also has a really melodic cry that I like.
Tapu Koko because electric Pokémon are my #1, and also because its shiny form is just so awesome. Lookie: It has to be my favorite shiny by a long shot. I was pleased with its role in the game, though I also do adore Tapu Lele a whole lot.
Tapu Koko, because it makes me think of Koko from Fosters Home for Imaginary Friends and Electric/Fairy is a chill type
To be honest, Tapu Koko has been my favorite Tapu since he was first revealed. He simply has an awesome look, great moves, and he's one of those Pokémon which, if I had the mind to go competitive, I would try to find a place for him on my team.
